TLV320AIC34

illustrate

The TLV320AIC34 is a four-channel headphone amplifier with a low-power quad-channel audio codec, as well as programmable single-ended or full-differential configurations for multiple inputs and outputs. Extensive register-based power control is included to enable four-channel 48 kHz DAC playback up to 15 MW low with a 3.3 V analog power supply, making it ideal for portable, battery-powered audio and telephony applications.

The TLV320AIC34 includes integrated mic bias, a CNC four-channel mic preamp, and multiple analog inputs between the mix/multiplex function Automatic Gain Control (AGC) in the recording path. Programmable filters are used for digital cameras with optical zoom that can record and remove audio noise that may occur during the process.
