LM2904A-TSR

Overview

The LM2904A-TSR is a dual operational amplifier manufactured by 3PEAK, housed in an 8-pin TSSOP package. It operates on a supply voltage range of 3 V to 36 V or ±1.5 V to ±18 V. Key electrical parameters include a gain-bandwidth product of 0.9 MHz and a slew rate of 0.5 V/μs. The device features low quiescent current consumption of 100 μA per channel and a maximum input offset voltage of ±3 mV. It supports rail-to-rail output swing and includes internal frequency compensation.

Feature Summary

• Rail-to-rail output capability with input common-mode voltage range extending to the negative supply rail.
• Low power consumption with 100 μA quiescent current per amplifier channel.
• High electromagnetic interference (EMI) immunity performance rated at 71 dB at 1 GHz.
• Internal frequency compensation ensures stability without external components.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'TSR' corresponds to the TSSOP-8 package and tape-and-reel quantity of 3000 units as defined in the manufacturer's order information table. Confirm that the component meets RoHS compatibility and halogen-free requirements specified under the 'Green' designation. Ensure design specifications align with the absolute maximum ratings for supply voltage and junction temperature limits.

Selection Notes

Select this component when single-supply operation down to 3 V is required alongside rail-to-rail output performance. The low offset voltage and high EMI rejection make it suitable for noisy industrial environments. Compare against standard bipolar op-amps if lower cost is prioritized over the enhanced AC performance and extended common-mode range provided by this CMOS architecture.

Part Context

This part belongs to the LM2904A/LM2902A series of general-purpose operational amplifiers from 3PEAK. The series utilizes proprietary design techniques to achieve stable frequency response and low offset characteristics. It serves as a modern replacement for legacy commercial op-amps, offering improved power efficiency and input/output voltage ranges while maintaining pin compatibility with industry-standard packages.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should verify pinout compatibility and electrical parameter margins when considering alternative manufacturers' dual op-amps.
