TLV320AIC26 具有立体声耳机/扬声器放大器和 12 位电池/温度 / Aux 的低功耗立体声音频编解码器
TLV320AIC26 描述
The TLV320AIC26 is a high-performance audio codec with 16/20/24/32-bit 97-dBA stereo playback, mono record functionality at up to 48 ksps. A microphone input includes built-in preamp and hardware automatic gain control, with single-ended or fully-differential input capability.
The audio output drivers on the ’AIC26 are highly flexible, having software-programmable low or high-power drive modes to optimize system power dissipation. The outputs can be configured to supply up to 325 mW into a bridge terminated 8-Ohm headphone amplifiers in ac-coupled or capless output configurations, and can supply a stereo line-level output.
A programmable digital audio effects processor enables bass, treble, midrange, or equalization playback processing.
