5.2 Overview
The TLV320AIC3120 is a highly integrated mono audio DAC and mono 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 2-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 TLV320AIC3120 consists of the following blocks:
• Microphone interfaces (analog and digital)
• Audio codec (mono ADC and mono DAC)
• AGC and DRC
• Two miniDSP digital signal-processing blocks (record and playback paths)
• Mono headphone/lineout amplifier
