LMV1088RLX/NOPB

Audio Amplifiers Overview

The LMV1088RLX/NOPB is a dual-input, far-field noise suppression microphone amplifier with automatic calibration capability. It amplifies near-field voice signals within 4 cm while rejecting far-field acoustic noise greater than 0.5 m from the microphones. The device consumes 1 mA of supply current and provides up to 20 dB of SNRI in a properly configured system. Key electrical parameters include a 60 dB typical signal-to-noise ratio (A-weighted), 0.1% total harmonic distortion, and an 85 dB power supply rejection ratio. Operating voltage ranges from 2.7 V to 5.5 V.

Audio Amplifiers Feature Summary

• Analog noise cancellation processor for superior performance over DSP solutions
• Automatic calibration via I2C interface or pin control
• On-board EEPROM storage for calibration coefficients
• Dual differential microphone inputs for excellent noise immunity

Audio Amplifiers Applications

• Mobile handsets
• Bluetooth and other powered headsets
• Hand-held voice microphones
• Portable public address systems

Audio Amplifiers Procurement Notes

Verify the specific suffix RLX against the official datasheet to confirm package type and reel specifications. Confirm that the component meets RoHS standards as indicated in the manufacturer's documentation. Ensure compatibility with the required operating temperature range of -40°C to +85°C for your application environment.

Audio Amplifiers Selection Notes

Select this component when low power consumption is critical compared to digital signal processing alternatives. Consider the 36-bump DSBGA package for space-constrained designs. Evaluate the need for automatic calibration to compensate for microphone gain mismatches and acoustical path variances during manufacturing.
