TLV320AIC32 具有 6 输入 6 输出集成耳机/扬声器放大器以及 3D 效果的低功耗立体声编解码器
TLV320AIC32 描述
The TLV320AIC32 is a low-power stereo-audio codec with a 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 14 mW from a 3.3-V analog supply, making it ideal for portable, battery-powered audio and telephony applications.
The record path of the TLV320AIC32 contains integrated microphone bias, digitally-controlled stereo-microphone pre-amp, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs. The playback path includes mix/mux capability from the stereo DAC and selected inputs, through programmable volume controls, to the various outputs.
