LM2904DMR2G

Instrumentation, Op Amps, Buffer Amps Overview

The LM2904DMR2G is a dual operational amplifier from onsemi, housed in an 8-pin Micro8 (MSOP) package. It operates within a single supply voltage range of 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. Key electrical characteristics include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/µs, and an input offset voltage of up to 7 mV at 25°C. The device draws a typical quiescent current of 1.2 mA per channel and provides an output short-circuit current capability of 40 mA. It supports an operating temperature range from -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix DMR2 corresponds to the Micro8 package and tape & reel shipping configuration as listed in the ordering information. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the operating temperature range requirements align with the industrial grade specification of -40°C to +105°C before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual amplifier with low power consumption and rail-to-rail input common mode capability is required. It is suitable for single-supply applications where the input signal approaches ground potential. Consider the 1 MHz bandwidth and 600 mV/µs slew rate for general-purpose signal conditioning tasks. Verify that the Micro8 package dimensions fit the available PCB space.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LM2904 series, which utilizes circuit designs perfected for quad operational amplifiers like the LM324. It serves as a dual-channel equivalent to half of an LM324. The series is designed for commercial, industrial, and military applications, offering advantages over standard op-amps in single-supply environments by allowing direct interfacing with digital systems without additional biasing networks.
