rev. e ad743 e7e op amp performance: jfet vs. bipolar the ad743 is the first monolithic jfet op amp to offer the low input voltage noise of an industry-standard bipolar op amp w ithout its inherent input current errors. this is demonstrated in figure 2, which compares input voltage noise versus input source resis- tance of the op27 and ad743 op amps. from this figure, it is clear that at high source impedance the low current noise of the ad743 also provides lower total noise. it is also important to note that with the ad743 this noise reduction extends all the way down to low source impedances. the lower dc current errors of the ad743 also reduce errors due to offset and drift at high source impedances (figure 3). 100 1k 10k 100k 1 10 100 1000 1m 10m source resistance (  ) op27 and resistor ad743 and resistor resistor noise only ad743 and resistor or op27 and resistor ( ) (? ? ?)

rev. e e8e ad743 figures 4 and 5 show two ways to buffer and amplify the output of a charge output transducer. both require using an amplifier that has a very high input impedance, such as the ad743. figure 4 shows a model of a charge amplifier circuit. here, amplifica- tion depends on the principle of conservation of charge at the input of amplifier a1, which requires that the charge on ca paci- tor c s be transferred to capacitor c f , thus yielding an output voltage of  q/c f . the amplifier?s input voltage noise will appear at the output amplified by the noise gain (1 + (c s /c f )) of the circuit. a1 * optional, see text c s c f c b * r b * r1 = c s c f r1 r2 r2 r b * figure 4. charge amplifier circuit a2 * optional, see text c s c b * r b * r1 r2 r b figure 5. model for a high z follower with gain the circuit in figure 5 is simply a high impedance follower with gain. here the noise gain (1 + (r1/r2)) is the same as the gain from the transducer to the output. in both circuits, resistor r b is required as a dc bias current return. there are three important sources of noise in these circuits. amplifiers a1 and a2 contribute both voltage and current noise, while resistor r b contributes a current noise of nk t r f b = 4  where k = boltzman?s constant = 1.381 10 e23 joules/kelvin t = absolute temperature, kelvin (0 c = 273.2 kelvin) f = bandwidth?in hz (assuming an ideal brick wall filter) this must be root-sum-squared with the amplifier?s own current noise. figure 6 shows that these circuits in figures 4 and 5 have an identical frequency response and noise performance (provided that c s /c f = r1/ r2). one feature of the first circuit is that a t network is used to increase the effective resistance of r b and to improve the low frequency cutoff point by the same factor. ?100 ?110 ?120 ?130 ?140 ?150 ?160 ?170 ?180 ?190 ?200 ?210 ?220 0.01 0.1 110 100 1k 10k 100 k frequency (hz) decibels referenced to 1v/ hz total output noise noise due to r b alone noise due to i b alone figure 6. noise at the outputs of the circuits of figures 4 and 5. gain = +10, c s = 3000 pf, r b = 22 m  however, this does not change the noise contribution of r b which, in this example, dominates at low frequencies. the graph of figure 7 shows how to select an r b large enough to minimize this resistor?s contribution to overall circuit noise. when the equivalent current noise of r b ((  4kt)/r equals the noise of i b (  2qi b b b b 4kt/r q 2qi t tr 4 k t 4q
rev. e ad743 e9e how chip package type and power dissipation affect input bias current as with all jfet input amplifiers, the input bias current of the ad743 is a direct function of device junction temperature, i b approximately doubling every 10 c. figure 8 shows the rela- tionship between the bias current and the junction temperature for the ad743. this graph shows that lowering the junction temperature will dramatically improve i b . ?60 ?40 ?20 0 20 40 60 80 100 120 140 10 ?12 10 ?11 10 ?10 10 ?9 10 ?8 10 ?7 10 ?6 input bias current (a) junction temperature (  c) t a = 25  c v s = 15v figure 8. input bias current vs. junction temperature the dc thermal properties of an ic can be closely approximated by using the simple model of figure 9, where current represents power dissipation, voltage represents temperature, and resistors represent thermal resistance (
rev. e e10e ad743 an input impedance compensated, sallen-key filter the simple high-pass filter of figure 13 has an important source of error which is often overlooked. even 5 pf of input capacitance in amplifier a will contribute an additional 1% of pass-band ampli- tude error, as well as distortion, proportional to the c/v characteristics of the input junction capacitance. the addition of the network designated z will balance the source impedance?as seen by a?and thus eliminate these errors. a 500k  500k  1000pf 1000pf +v s ?v s z 1000pf 1000pf 500k  500k  z figure 13. input impedance compensated sallen-key filter two high performance accelerometer amplifiers two of the most popular charge-out transducers are hydro phones and accelerometers. precision accelerometers are typically cali- brated for a charge output (pc/ g ). * figures 14a and 14b show two ways in which to configure the ad743 as a low noise charge amplifier for use with a wide variety of piezoelectric accelerom- eters. the input sensitivity of these circuits will be determined by the value of capacitor c 1 and is equal to   v q c out out = 1 the ratio of capacitor c 1 to the internal capacitance ( c t ) of the transducer determines the noise gain of this circuit (1 + c t / c 1). the amplifier?s voltage noise will appear at its output amplified by this amount. the low frequency bandwidth of these circuits will be dependent on the value of resistor r 1. if a t network is used, the effective value is r 1(1 + r 2/ r 3). ad743 r2 9k  r1 110m  (5  22m  ) output 0.8mv/pc * c1 1250pf r3 1k  b and k model 4370 or equivalent * pc = picocoulombs g = earth?s gravitational constant figure 14a. basic accelerometer circuit ad743 r3 1k  r2 9k  r4 18m  r1 110m  (5  22m  ) r5 18m  output 0.8mv/pc c1 1250pf c3 2.2  f c2 2.2  f b and k model 4370 or equivalent ad711 figure 14b. accelerometer circuit using a dc servo amplifier a dc servo loop (figure 14b) can be used to assure a dc output which is <10 mv, without the need for a large compensating resistor when dealing with bias currents as large as 100 na. for optimal low frequency performance, the time constant of the servo loop ( r 4 c 2 = r 5 c 3) should be time cons r r r c tant +    
10 1 1 2 3 1 low noise hydrophone amplifier hydrophones are usually calibrated in the voltage out mode. the circuits of figures 15a and 15b can be used to amplify the output of a typical hydrophone. figure 15a shows a typical dc-coupled circuit. the optional resistor and capacitor serve to counteract the dc offset caused by bias currents flowing through resistor r1. figure 15b, a variation of the original circuit, has a low frequency cutoff determined by an rc time constant equal to time cons t c c tan = 1 2 100  r2 1900  r4 * 10 8  r1 10 8  r3 100  output ad743 * optional, see text input sensitivity = ?179 db re. 1v/  pa ** ** 1v per micropascal b and k type 8100 hydrophone c t c1 * figure 15a. basic hydrophone amplifier
