5.2 Overview
The TLV320AIC3100 is a highly integrated stereo audio DAC and monaural ADC for portable computing,
communication, and entertainment applications. A register-based architecture eases integration with
microprocessor-based systems through standard serial-interface buses. This device supports the two-wire
I
2
C bus interface, which provides full register access. All peripheral functions are controlled through these
registers and the onboard state machines.
The TLV320AIC3100 consists of the following blocks:
• Microphone interfaces (analog and digital)
• Audio codec (mono ADC and stereo DAC)
• AGC and DRC
• Two digital signal-processing blocks (record and playback paths)
• Digital sine-wave generator for beep
