DESCRIPTION

· The TLV320AIC3106 is a low-power stereo audio codec with a stereo headphone amplifier and multiple programmable inputs/outputs in single-ended or fully differential configurations. It features extensive register-based power control, enabling efficient 48-kHz DAC playback at just 15 mW from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications. The device includes integrated microphone bias, a digitally controlled stereo microphone preamplifier, and automatic gain control (AGC) in the record path, with mix/mux capability among multiple analog inputs. Programmable filters are available during recording to remove audible noise, such as that from optical zooming in digital cameras.

FEATURES

· Stereo audio DAC with 102-dBA SNR, supporting 16-, 20-, 24-, 32-bit data and rates from 8 kHz to 96 kHz, with 3D, bass, treble, EQ, and de-emphasis effects.
· Stereo audio ADC with 92-dBA SNR, supporting rates from 8 kHz to 96 kHz, with digital signal processing and noise filtering during recording.
· Ten audio input pins programmable in single-ended or fully differential configurations with 3-state capability.
· Seven audio output drivers including stereo fully differential or single-ended headphone drivers, fully differential stereo line outputs, and a fully differential mono output.
· Low power consumption: 15-mW stereo 48-kHz playback with a 3.3-V analog supply.
· Ultralow-power mode with passive analog bypass.
· Programmable input/output analog gains and microphone bias level.
