Texas Instruments TLV320AIC3107 Low-Power Stereo CODECs

Texas Instruments TLV320AIC3107 Low-Power Stereo CODECs incorporate a stereo headphone amplifier, mono class-D speaker driver, and multiple inputs/outputs programmable in single-ended or fully differential configurations. The TI TLV320AIC3107 includes an extensive register-based power control allowing stereo 48kHz DAC playback as low as 15mW from a 3.3V analog supply. These features make the TLV320AIC3107 ideal for portable battery-powered audio and telephony applications.
