LM2902A-SR

Overview

The LM2902A-SR is a quad general-purpose operational amplifier manufactured by 3PEAK. It operates on a supply voltage of 3 V to 36 V or ±1.5 V to ±18 V with a quiescent current of 100 μA per channel. 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. The device features rail-to-rail output capability and an input common-mode voltage range that includes ground. It is housed in a 14-SOP package and supports an operating temperature range from –40°C to 125°C.

Feature Summary

• Rail-to-rail output capability for extended dynamic range
• Input common-mode voltage range extends to the negative supply rail
• Low power consumption with 100 μA quiescent current per amplifier
• High electromagnetic interference rejection performance

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SR designation corresponds to the SOP14 form factor. Confirm RoHS compliance and halogen-free status requirements against project specifications. Ensure ESD handling protocols are followed during assembly due to the sensitivity of the CMOS/TTL compatible inputs. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and thermal characteristics before finalizing procurement orders.

Selection Notes

Select this component when a low-power, single-supply operational amplifier with rail-to-rail output is required. It serves as a direct replacement for standard quad op-amps in cost-sensitive designs. Consider the 0.9 MHz bandwidth and 0.5 V/μs slew rate for moderate-speed signal processing tasks. Verify that the input common-mode range including ground meets the system's signal grounding requirements.

Part Context

This part belongs to the LM2904A/LM2902A series of high-supply voltage amplifiers designed by 3PEAK. The series utilizes proprietary design techniques to achieve stable frequency response and low offset voltage. The LM2902A variant specifically integrates four independent amplifiers within a single package, offering a compact solution for multi-channel applications compared to dual-amplifier alternatives.
