TLV320AIC26IRHBG4

Product Summary

The TLV320AIC26IRHBG4 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 driver on the TLV320AIC26IRHBG4 is highly flexible, having software-programmable low or high-power drive mode to optimize system power dissipation. The output can be configured to supply up to 325 mW into a bridge terminated 8-Ω load, can support stereo 16-Ω headphone amplifiers in ac-coupled or capless output configurations, and can supply a stereo line-level output. Applications are (1)Cellular and smart phones; (2)MP3 players; (3)Digital still cameras; (4)Digital video camcorders.
