LM2902A-TR

Overview

The LM2902A-TR is a quad general-purpose operational amplifier manufactured by 3PEAK, housed in a TSSOP14 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, 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 extending to the negative rail.

Feature Summary

• Rail-to-rail output swing capability
• Input common-mode voltage range includes ground
• Excellent EMI suppression performance
• Low power consumption with stable frequency response

Applications

• Power modules
• Sensor interfaces
• Motor control systems
• Audio applications

Procurement Notes

Verify that the ordering suffix matches the required package type, as the TR suffix indicates the TSSOP14 variant. Confirm RoHS compliance and halogen-free status for environmental requirements. Ensure the operating temperature range aligns with system specifications. Cross-reference pinout configurations to guarantee compatibility with existing PCB layouts before finalizing procurement orders.

Selection Notes

Select this component when high supply voltage tolerance up to 36 V is required alongside low power consumption. The rail-to-rail output and ground-referenced input make it suitable for single-supply designs. Consider the 0.9 MHz bandwidth and 0.5 V/μs slew rate for moderate-speed signal processing tasks requiring stable AC performance.

Part Context

This part belongs to the LM2904A/LM2902A series of 36-V general-purpose operational amplifiers from 3PEAK. The series utilizes proprietary design techniques to achieve low offset and low power characteristics. The LM2902A specifically integrates four independent amplifiers within a single package, serving as a plug-in replacement for commercially available op amps to improve performance.
