LM2902AMX

Overview

The LM2902AMX is a quad operational amplifier manufactured by onsemi, housed in a 14-SOP package. It operates from a single power supply ranging from 3V to 26V or split supplies of ±1.5V to ±13V. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 600 mV/µs, and an input offset voltage of 7 mV. The device features an input bias current of 250 nA, a supply current of 1.2 mA, and an output current capability of 40 mA per channel. It supports a common-mode rejection ratio of 70 dB and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Internally frequency compensated for unity gain stability
• Input common-mode voltage range includes ground potential
• Large output voltage swing extending to the negative rail
• Low power drain suitable for battery-powered operation

Applications

• Transducer amplifiers
• DC gain blocks
• Single power supply systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the component meets all necessary regulatory standards for the intended application environment. Review the datasheet for absolute maximum ratings to prevent damage during installation and operation.

Selection Notes

Select this component when a quad amplifier with single-supply compatibility and ground-referenced inputs is required. Ensure the design accommodates the specified 26V maximum supply voltage and the -40°C to +85°C operating temperature range. Verify that the 1 MHz bandwidth and 600 mV/µs slew rate meet the signal processing requirements.

Part Context

This part belongs to the LM2902/LM2902A series of low-power quad operational amplifiers designed specifically for automotive and industrial control systems. It shares architectural similarities with the LM324 but offers distinct electrical characteristics tailored for wider voltage ranges and specific industrial environments.
