LM4935RL/NOPB

Audio Amplifiers Overview

The LM4935RL/NOPB is a Class D audio amplifier manufactured by Texas Instruments, housed in a 49-DSBGA package. It operates on a supply voltage ranging from 2.7V to 5.5V and supports an operating temperature range of -40°C to 85°C. The device delivers a maximum output power of 1.3W into an 8-ohm load for single-channel mono operation, or 52mW per channel into a 16-ohm load for stereo headphone applications. It integrates digital control interfaces including I2C, I2S, PCM, and SPI.

Audio Amplifiers Feature Summary

Integrates digital audio interfaces such as I2C, I2S, PCM, and SPI for system control and configuration.
Includes built-in protection mechanisms against short circuits and thermal overload conditions.
Features integrated Depop circuitry to eliminate pop noise during power-up and power-down sequences.

Audio Amplifiers Applications

Mono speaker amplification in portable electronic devices
Stereo headphone driver circuits
Digital audio systems requiring I2C or I2S interface control

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized channels due to the part's End-of-Life status. Confirm RoHS3 compliance and MSL Level 1 classification before integration. Check for valid replacement options as this specific package may no longer be in active production.

Audio Amplifiers Selection Notes

Select this component for designs requiring a compact Class D solution with digital control capabilities. Ensure the application fits within the 2.7V to 5.5V supply range. Consider the 49-DSBGA footprint constraints and verify that the required output power aligns with the specified load impedances.

Audio Amplifiers Part Context

This device belongs to the Boomer series of audio amplifiers from Texas Instruments. It is designed for low-power audio applications where efficiency and small form factor are critical. The NOPB suffix indicates lead-free construction compliant with environmental standards.
