Description 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 of TLV320AIC26 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-Ω load, can support stereo 16-Ω headphone amplifiers in ac-coupled or capless output configurations, and can supply a stereo line-level output
A programmable digital audio TLV320AIC26 effects processor enables bass, treble, midrange, or equalization playback processing. The digital audio data format is programmable to work with popular audio standard protocols (I2S, DSP, Left/Right Justified) in master or slave mode, and also includes an on-chip programmable PLL for flexible clock generation capability. Highly configurable software power control of TLV320AIC26 is provided, enabling stereo audio playback at 48 ksps at 11 mW with a 3.3-V analog supply level.
The TLV320AIC26 offers a 12-bit measurement ADC and internal reference voltage, as well as two battery measurement inputs capable of reading battery voltages up to 6 V, while operating at an analog supply as low as 2.7 V. It includes an on-chip temperature sensor capable of reading 0.3°C resolution. The TLV320AIC26 is available in a 32 lead QFN.
