TLV320AIC33IZQER

Product Summary

The TLV320AIC33IZQER is a low power stereo audio codec with stereo headphone amplifier, as well as multiple inputs and outputs programmable in single-ended or fully-differential configurations. Extensive register-based power control is included, enabling stereo 48-kHz DAC playback as low as 15mW(TBD) from a 3.3V analog supply, making it ideal for portable battery-powered audio and telephony applications. The record path of the TLV320AIC33IZQER contains integrated microphone bias, digitally controlled stereo microphone preamp, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs.
