TLV320AIC31IRHBR Datasheet PDF - TI

●DESCRIPTION

●The TLV320AIC31 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 digital-to-analog converter (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.
