ALM2402FQPWPRQ1

Overview

The ALM2402F-Q1 is an automotive-grade, dual operational amplifier featuring high current output capabilities. It operates within a supply voltage range of 4.5 V to 16 V and supports junction temperatures from -40°C to 150°C. Key electrical specifications include a gain-bandwidth product of 600 kHz, a slew rate of 0.17 V/µs, and an input bias current of 1.5 nA. The device delivers up to 400 mA per channel with full-swing output capability and maintains a maximum input offset voltage of 1 mV.

Feature Summary

• High current output capability suitable for driving low-impedance loads
• Designed specifically for resolver excitation applications in automotive environments
• Full-swing output operation maximizing dynamic signal range

Applications

• Resolver excitation circuits
• Automotive sensor signal conditioning
• Industrial control systems requiring high drive strength

Procurement Notes

Verify the specific suffix 'FQ' against the official Texas Instruments datasheet to confirm component revision and qualification status. Ensure the ordering part number matches the exact package and tape-and-reel specifications required for the manufacturing process. Cross-reference the AEC-Q100 grade requirements with system-level reliability standards before finalizing procurement.

Selection Notes

Select this component when high output current is necessary for direct load driving without additional buffering stages. The dual-channel configuration reduces board space compared to single amplifiers. Verify that the 600 kHz bandwidth meets the frequency requirements of the target application, particularly for resolver excitation signals where phase accuracy is critical.

Part Context

This device belongs to the ALM2402 family of automotive operational amplifiers. It is designed to replace older discrete solutions or lower-performance op-amps in demanding automotive environments. The HTSSOP package provides thermal efficiency while maintaining a compact footprint for modern vehicle electronics.

Replacement Considerations

Check for pin-compatible alternatives such as the ALM2402QPWPRQ1 if different qualification grades are required. Verify that any substitute maintains the same 400 mA output current capability and 14-pin HTSSOP package dimensions.
