LM2902KVQPWR

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902KVQPWR is a quad ground sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single power supply with a voltage range of 3.0V to 32.0V and supports dual supplies from ±1.5V to ±16V. The device features an operating temperature range of -40°C to +125°C, an input offset voltage maximum of 4.5mV at 25°C, and a typical input bias current of 20nA. It provides a large signal voltage gain of 100dB, a common-mode rejection ratio of 80dB, and a gain bandwidth product of 0.8MHz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'PWR' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure the component meets the required industrial temperature grade (-40°C to +125°C) for your design environment. Cross-reference the datasheet revision date to confirm electrical characteristics match your schematic requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-power, quad-channel amplifier is needed that can interface directly with ground-referenced signals. It is suitable for applications requiring operation over a wide voltage range without negative supply rails. Consider the thermal dissipation limits in SOP-J14 packages if driving significant output currents at high ambient temperatures.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM2902xxx series of ground sense operational amplifiers produced by ROHM Semiconductor. It is part of a family that includes dual (LM2904), quad (LM2902), and other variants like LM358 and LM324. These devices are designed as general-purpose amplifiers offering low current consumption and high gain, making them standard choices for cost-sensitive consumer and industrial electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible replacements include the LM2902KVQDRQ1 from Texas Instruments and the MC33078 from ON Semiconductor. Verify pin compatibility and electrical parameter margins before substitution.
