amps. all devices are fabricated in a new precision 40v complementary bipolar di process. a super-beta npn input stage with input bias current cancellation provides low input bias current (1na typical), low input offset voltage (10v typical), low input noise voltage (3nv/ ? hz) and low 1/f noise corner frequency (5hz). these amplifiers also feature high open loop gain (1500v/mv) for excellent cmrr (120db) and thd+n performance (0.0002% at 3.5v rms , 1khz into 2k ). a complimentary bipolar output stage enables high capacitive load drive without external compensation. operating voltage range the devices are designed to operate over the 4.5v (2.25v) to 40v (20v) range and are fully characterized at 10v (5v) and 30v (15v). parameter variation with operating voltage is shown in the ?typical performance curves? beginning on page 13 . input esd diode protection the input terminals (in+ and in-) have internal esd protection diodes to the positive and negative supply rails and an additional anti-parallel diode pair across the inputs (see figures 38 and 39 ). for unity gain applications (see figure 38 ) where the output is connected directly to the non-inverting input a current limiting resistor (r in ) will be needed under the following conditions to protect the anti-parallel differential input protection diodes. ? the amplifier input is supplied from a low impedance source. ? the input voltage rate-of-rise (dv/dt) exceeds the maximum slew rate of the am plifier (3.6v/s). if the output lags far enough be hind the input, the anti-parallel input diodes can conduct. for ex ample, if an input pulse ramps from 0v to +10v in 1s, then the output of the amplifier will reach only +3.6v (slew rate = 3.6v/s) while the input is at 10v, the input differential voltage of 6.4v will force input esd diodes to conduct, dumping the input current directly into the output stage and the load. the resulting current flow can cause permanent damage to the esd diodes. the esd diodes are rated to 20ma and in the previous example, setting r in to 1k resistor (see figure 38 ) would limit the current to < 6.4ma and provide additional protection up to 20v at the input. in applications where one or both amplifier input terminals are at risk of exposure to high voltage, current limiting resistors may be needed at each input terminal (see figure 39 r in+, r in- ) to limit current through the power supply esd diodes to 20ma. output current limiting the output current is internally limited to approximately 45ma at +25c and can withstand short-circ uit to either rail as long as the power dissipation limits are not exceeded. this applies to only 1 amplifier at a time for the dual op amp. continuous operation under these conditio ns may degrade long term reliability. output phase reversal output phase reversal is a change of polarity in the amplifier transfer function when the input voltage exceeds the supply voltage. the isl28127, isl28227 and isl28227seh are immune to output phase reversal, even when the input voltage is 1v beyond the supplies. unused channels the user must configure unused channels to prevent them from oscillating. the unused channel( s) oscillates if the input and output pins are floating. this re sults in higher than expected supply currents and possible no ise injection into the other channel(s) being used. the proper way to prevent this oscillation is to short the output to the inverting input and ground the positive input, as shown in figure 40 . power dissipation it is possible to exceed the +150c maximum junction temperatures under certain load and power supply conditions. it is therefore important to ca lculate the maximum junction temperature (t jmax ) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. these parameters are related using equation 1 : figure 38. input esd diode current limiting

actual device and simulates important ac and dc parameters. ac parameters incorporated into the model are: 1/f and flatband noise, slew rate, cmrr, gain and phase. the dc parameters are v os , i os , total supply current and output voltage swing. the mode l does not model input bias current. the model uses typical pa rameters given in the ?electrical specifications? table beginning on page 6 . the a vol is adjusted for 128db with the dominant pole at 5hz. the cmrr is set higher than the ?electrical specifications? table beginning on page 6 to better match design simulations (150db, f = 50hz). the input stage models the actual device to present an accurate ac representation. the model is configured for +25c ambient temperature. the spice model for the isl28227seh can be found here
