资 源 简 介
The TLV320AIC34 is a low-power four-channel audio codec with four-channel 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 four-channel 48-kHz DAC playback as low as 15 mW from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applicaTIons.
The record path of the TLV320AIC34 contains integrated microphone bias, digitally controlled four-channel microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog inputs. Programmable filters are available during record which can remove audible noise that can occur during optical zooming in digital cameras.
