TLV320DAC32IRHBR

Product Summary

The TLV320DAC32IRHBR is a low power stereo audio DAC with and integrated power amplifier designed to drive stereo headphones or speakers. The TLV320DAC32IRHBR also has a pair of analog inputs which allow routing of external signals to the output amplifiers. The playback path includes a mix/mux capability from the stereo DAC and analog inputs, through programmable volume controls, to the headphone outputs. Extensive register-based power control is included, enabling stereo 96-kHz playback as low as 20mW from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications.
