LMV1089VYX/NOPB

Audio Amplifiers Overview

The LMV1089VYX/NOPB is a dual-channel far-field microphone preamplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 1.1 mA. The device features a total harmonic distortion plus noise of 0.1%, a common-mode rejection ratio of 62 dB, and a power supply rejection ratio of 91 dB. It utilizes an LQFP-32 surface-mount package and supports single-ended input and output signals. The component functions in Class-AB mode with a shutdown capability and is rated for operation between -40°C and +85°C.

Audio Amplifiers Feature Summary

• Dual-channel architecture designed specifically for far-field noise suppression applications
• Integrated shutdown control for power management
• High power supply rejection ratio to minimize noise interference

Audio Amplifiers Applications

• Far-field microphone array systems
• Voice recognition modules
• Conference phone audio front-ends

Audio Amplifiers Procurement Notes

Verify the specific suffix 'VYX' against official documentation, as standard listings often reference 'VY'. Confirm lifecycle status, as related variants may be marked Not Recommended for New Designs. Ensure compatibility with required packaging formats and check for moisture sensitivity level requirements during storage and handling procedures.

Audio Amplifiers Selection Notes

Select this component for designs requiring integrated noise suppression in dual-microphone configurations. Evaluate the LQFP-32 footprint constraints and verify that the 2.7 V minimum supply voltage aligns with system power rails. Consider the thermal performance within the specified industrial temperature range when finalizing the layout.

Audio Amplifiers Part Context

This part belongs to the LMV1089 series of audio amplifiers from Texas Instruments. It is distinct from general-purpose operational amplifiers like the LMV792 or other microphone preamps such as the LMV1012. The series focuses on specialized audio signal conditioning with built-in noise reduction capabilities rather than generic amplification tasks.

Audio Amplifiers Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify if alternative packages or suffixes offer identical electrical characteristics. Confirm availability status as older revisions may be discontinued.
