LMV1088RL/NOPB

Audio Amplifiers Overview

The LMV1088RL/NOPB is a dual-input, far-field noise suppression microphone amplifier with automatic calibration capability. It operates on a supply voltage of 2.7V to 5.5V and consumes 1mA typical supply current. The device provides a signal-to-noise ratio of 60dB (A-weighted) and total harmonic distortion of 0.1%. It features up to 20dB of noise cancellation and 85dB power supply rejection ratio. The component utilizes a 36-bump DSBGA package and supports I2C interface for configuration.

Audio Amplifiers Feature Summary

• Amplifies near-field voice signals while rejecting far-field acoustic noise
• Includes automatic calibration to compensate for microphone gain mismatch and acoustical path variances
• Stores calibration coefficients in onboard EEPROM via I2C or pin control
• Provides differential microphone inputs for excellent noise immunity

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify the specific suffix RL/NOPB against the manufacturer's official documentation to confirm package type and RoHS compliance status. Confirm that the intended application environment falls within the specified operating temperature range of -40°C to +85°C. Ensure the design accommodates the required I2C pull-up resistors and connects unused NC pins to ground for optimal noise performance as detailed in the datasheet.

Audio Amplifiers Selection Notes

Select this component when low power consumption is critical compared to DSP-based solutions. It is suitable for applications requiring analog noise cancellation without added processing delay. Consider the 36-bump DSBGA package constraints for PCB layout. Verify that the system can support the necessary I2C communication protocol for calibration and gain adjustment functions.

Audio Amplifiers Part Context

The LMV1088 belongs to Texas Instruments' Powerwise family of energy-efficient solutions. It is designed to replace digital signal processing approaches in microphone arrays by providing superior performance with significantly lower power consumption. The device integrates pre-amplification, noise cancellation, and post-amplification stages into a single compact package.
