LM2904A-VR

Overview

The LM2904A-VR is a dual general-purpose operational amplifier manufactured by 3PEAK, housed in an MSOP8 package. It operates on a supply voltage range of 3 V to 36 V or ±1.5 V to ±18 V. Key electrical specifications include a gain-bandwidth product of 0.9 MHz, a slew rate of 0.5 V/μs, and a maximum input offset voltage of ±3 mV at 25°C. The device draws a quiescent current of 100 μA per channel and features rail-to-rail output capability with an input common-mode voltage range that includes ground. It supports an operating temperature range from –40°C to 125°C.

Feature Summary

• Features excellent EMI suppression performance rated at 71 dB at 1 GHz.
• Incorporates proprietary design techniques for stable frequency response and low power consumption.
• Capable of functioning as comparators while maintaining high DC voltage gain.

Applications

• Power module systems
• Sensor interface circuits
• Motor control applications
• Audio signal processing

Procurement Notes

Verify the specific ordering suffix VR corresponds to the MSOP8 package configuration before procurement. Confirm that the tape and reel quantity matches project requirements, as this variant is supplied in reels of 3000 units. Ensure compatibility with RoHS standards and halogen-free manufacturing processes specified by the manufacturer.

Selection Notes

Select this component when single-supply operation with ground-referenced inputs is required alongside rail-to-rail output swing. The low quiescent current makes it suitable for battery-powered designs. Consider the 0.9 MHz bandwidth and 0.5 V/μs slew rate for moderate-speed signal conditioning tasks requiring high precision and low offset voltage.

Part Context

This part belongs to the LM2904A/LM2902A series of high-supply voltage amplifiers designed by 3PEAK. The series utilizes patented design techniques to achieve AC performance comparable to commercial op amps while offering improved input/output ranges. The LM2904A specifically provides two independent amplifiers in a compact footprint, serving as a drop-in replacement for legacy industry-standard devices.

FAQ

Does the input common-mode voltage range include the negative supply rail?

Yes, the input common-mode voltage range extends to the negative supply rail (−VS), allowing for ground-referenced input signals in single-supply configurations.

What is the maximum input offset voltage drift over temperature?

The input offset voltage temperature drift is specified as 7 μV/°C across the operating temperature range of –40°C to 125°C.
