DESCRIPTION

· The TLV320AIC3106 is a low-power stereo audio codec designed for portable audio and telephony applications, featuring a stereo headphone amplifier and multiple programmable inputs and outputs.

· It supports extensive register-based power control, enabling efficient stereo 48-kHz DAC playback at just 15 mW from a 3.3-V analog supply.

· The record path includes integrated microphone bias, a digitally controlled stereo microphone preamplifier, and automatic gain control (AGC), with mix/mux capabilities among multiple analog inputs.

· Programmable filters are available during recording to remove audible noise, particularly useful in digital cameras during optical zooming.

FEATURES

· Stereo audio DAC with 102-dBA SNR, supporting 16- to 32-bit data and sample rates from 8 kHz to 96 kHz, with 3D, bass, treble, EQ, and de-emphasis effects.

· Stereo audio ADC with 92-dBA SNR, supporting sample 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 for floating inputs.

· 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 at 15 mW for stereo 48-kHz playback with a 3.3-V analog supply, and an ultralow-power mode with passive analog bypass.

· Programmable input/output analog gains, AGC for recording, and programmable microphone bias level.

· Programmable PLL for flexible clock generation, with control bus selectable between SPI or I2C.

· Audio serial data bus supports I2S, left- and right-justified, DSP, and TDM modes, with an alternate serial PCM, I2S data bus for easy Bluetooth module connection.

· Concurrent digital and analog microphone support, extensive modular power control, and power supplies ranging from 2.7 V to 3.6 V for analog, 1.65 V to 1.95 V for digital core, and 1.1 V to 3.6 V for digital I/O.

APPLICATIONS

· Digital cameras.

· Smart cellular phones.
