LM2902M

The Texas Instruments LM2902M is a versatile quad operational amplifier designed for general-purpose applications. It offers internal frequency compensation for unity gain stability and a wide bandwidth of 1 MHz. The device supports a broad power supply range, from a single 3 V to 32 V supply, or dual supplies from ±1.5 V to ±16 V. Its very low supply current drain is approximately 700 µA, making it suitable for battery-powered applications. The LM2902M also features low input biasing current of 45 nA and a low input offset voltage of 2 mV. The input common-mode voltage range includes ground, and the output voltage can swing to ground even when operated from a single supply. This operational amplifier is available in a 14-pin SOIC package.

Key electrical characteristics include a large DC voltage gain of 100 dB and an output voltage swing that can reach close to the power supply rails. The differential input voltage range is equal to the power supply voltage. These features make the LM2902M suitable for various analog signal processing tasks where low power consumption and a wide operating voltage are critical.

The LM2902M is housed in a 14-pin SOIC (D) package, designed for through-hole or surface-mount assembly. The operating temperature range is -40°C to 85°C. This component is well-suited for applications requiring multiple op-amps in a single package, simplifying circuit design and reducing board space.
