ALM2402QDRRRQ1

Overview

The ALM2402QDRRRQ1 is an automotive-grade, dual-channel power operational amplifier manufactured by Texas Instruments. It features a wide supply voltage range from 4.5 V to 16 V and delivers a continuous output current of 400 mA per channel with rail-to-rail output swing. The device operates within an extended temperature range of -40°C to +150°C and is qualified under AEC-Q100 standards. Key electrical characteristics include a gain-bandwidth product of 600 kHz, a slew rate of 0.17 V/µs, and low input bias current of 1.5 nA. It is housed in a 14-HTSSOP package.

Feature Summary

• Dual-channel power amplification with full rail-to-rail output swing capability
• High output drive strength delivering 400 mA per channel
• Extended thermal operation rated for junction temperatures up to 150°C
• Automotive qualification compliant with AEC-Q100 reliability standards

Applications

• Automotive active suspension systems requiring high current drive
• Vehicle lighting control circuits for LED or lamp actuation
• Thermal management fan and pump motor drivers
• Power seat adjustment and window lift actuators

Procurement Notes

Verify the specific suffix 'RRR' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets the required AEC-Q100 grade for your target automotive application. Cross-reference the 14-HTSSOP footprint with your PCB design guidelines to ensure compatibility with assembly processes.

Selection Notes

Select this component when a dual-channel solution is required for applications demanding significant load current near the supply rails. The 600 kHz bandwidth supports moderate-speed signal processing tasks. Consider the 150°C operating limit for environments with limited cooling. Compare against single-channel alternatives if only one amplifier path is utilized to optimize board space.

Part Context

This part belongs to the ALM2402-Q1 family of power operational amplifiers designed for robust automotive environments. It complements other Texas Instruments linear devices such as precision amplifiers and instrumentation amplifiers. The dual-channel configuration allows for cost-effective implementation of differential drive stages or independent control loops within compact electronic control units.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same family. Verify that any replacement maintains the 400 mA output current and 16 V maximum supply rating. Ensure the alternative device also holds AEC-Q100 certification if automotive reliability is mandatory.
