LM2904WH Low-power dual operational amplifier Datasheet - production data Description This circuit consists of two independent, high- gain, operational amplifiers that have frequency compensation implemented internally. The circuit is designed specifically for automotive and industrial control systems. It operates from a MiniSO8 SO8 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 can now 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 which easily provides the required interface Wafer form electronics without requiring any additional power supply. In linear mode, the input common-mode voltage Features range includes ground and the output voltage can • Frequency compensation implemented also swing to ground even though it is operated internally from a single-power supply. • Large DC voltage gain: 100 dB • Wide bandwidth (unity gain: 1.1 MHz temperature compensated) • Very low-supply current per operator (500 µA) • Low input bias current: 20 nA (temperature compensated) • 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 April 2015 DocID9876 Rev 8 1/17 This is information on a product in full production. www.st.com

This is not destructive if the current does not exceed 5 mA as indicated, and normal output is restored for input voltages above -0.3 V. (2) Short-circuits from the output to VCC can cause excessive heating if VCC+ is < 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 (3)Short-circuits can cause excessive heating and destructive dissipation. Values are typical. (4) Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ 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 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). 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.

(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. 8/17 DocID9876 Rev 8
