Overview
The LP2902PWR is a quadruple low-power operational amplifier produced by Texas Instruments. It is particularly suited for battery-operated applications due to its ultra-low supply current and wide supply-voltage range. The LP2902PWR features four independent operational amplifiers in a single package, making it ideal for applications where space and power efficiency are crucial.
The device operates over a temperature range of -40°C to 85°C and is available in a TSSOP (PW) package with 14 pins. It is pin-compatible with the LM324, offering a convenient upgrade path for existing designs.
