DESCRIPTION
The TLV320AIC3106 is a low-power stereo audio codec with stereo headphone amplifier, as well as multiple
inputs and outputs programmable in single-ended or fully differential configurations. Extensive register-based
power control is included, enabling stereo 48-kHz DAC playback as low as 15 mW from a 3.3-V analog supply,
making it ideal for portable battery-powered audio and telephony applications.
The record path of the TLV320AIC3106 contains integrated microphone bias, digitally controlled stereo
microphone preamplifier, and automatic gain control (AGC), with mix/mux capability among the multiple analog
inputs. Programmable filters are available during record which can remove audible noise that can occur during
optical zooming in digital cameras. The playback path includes mix/mux capability from the stereo DAC and
selected inputs, through programmable volume controls, to the various outputs.
The TLV320AIC3106 contains four high-power output drivers as well as three fully differential output drivers. The
high-power output drivers are capable of driving a variety of load configurations, including up to four channels of
single-ended 16-
headphones using ac-coupling capacitors, or stereo 16- headphones in a capacitorless
output configuration.
