| LM2904WH Low power dual operational amplifier Features Internally frequency compensated Large DC voltage gain: 100 dB Wide bandwidth (unity gain: 1.1 MHz temperature compensated) Very low supply current per operator (500 A) Low input bias current: 20 nA (temperaturecompensated) Low input offset current: 2 nA Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Large output voltage swing 0 V to VCC - 1.5 V Internal ESD protection: - 2 kV HBM - 200 V MM Wafer form D SO-8 (Plastic micropackage) Description This circuit consists of two independent, highgain, internally frequency-compensated operational amplifiers, designed specifically for automotive and industrial control systems. It operates from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied from standard +5 V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.

Short-circuits from the output to VCC can cause excessive heating if VCC+ > 15 V. The maximum output current is approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 3. This input current only exists when the voltage values applied on the inputs is beyond the supply voltage line limits. This is not destructive if the current does not exceed 5 mA as indicated, and normal output is restored for input voltages above -0.3V. 4. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 5. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5). This is done for all couples of connected pin combinations while the other pins are floating. 6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. Table 2.

The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so there is no change in the loading charge on the input lines. 3. Due to the proximity of external components, ensure that stray capacitance does not cause coupling between these external parts. Typically, this can be detected because this type of capacitance increases at higher frequencies. 5/12 Electrical characteristics LM2904WH Figure 3. 120 Open loop frequency response TAmbient=+25C Figure 4. 20 Large signal frequency response 100k 1k OUTPUT SWING (Vpp) 100 80 GAIN (dB) 60 40 20 0 0 10 TAmbient=+150C TAmbient=+125C - +15V VO 15 VI +7V + 2k 10 5 0 10 1 10 2 10 3 10 4 10 5 10 6 1k 10k 100k 1M FREQUENCY (Hz) FREQUENCY (Hz) Figure 5.
