DESCRIPTION
The TLV320AIC3104 is a low-power stereo audio
codec with stereo headphone amplifier, as well as
multiple inputs and outputs that are programmable in
single-ended or fully differential configurations.
Extensive register-based power control is included,
enabling stereo 48-kHz DAC playback as low as 14
mW from a 3.3-V analog supply, making it ideal for
portable battery-powered audio and telephony
applications.
The record path of the TLV320AIC3104 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 TLV320AIC3104 contains four high-power
output drivers as well as two 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 capless output configuration.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
The stereo audio DAC supports sampling rates from 8 kHz to 96 kHz and includes programmable digital filtering
in the DAC path for 3D, bass, treble, midrange effects, speaker equalization, and de-emphasis for 32-kHz,
44.1-kHz, and 48-kHz sample rates. The stereo audio ADC supports sampling rates from 8 kHz to 96 kHz and is
preceded by programmable gain amplifiers or AGC that can provide up to 59.5-dB analog gain for low-level
microphone inputs. The TLV320AIC3104 provides an extremely high range of programmability for both attack
(8–1,408 ms) and for decay (0.05–22.4 seconds). This extended AGC range allows the AGC to be tuned for
many types of applications.
For battery saving applications where neither analog nor digital signal processing are required, the device can
be put in a special analog signal passthrough mode. This mode significantly reduces power consumption, as
most of the device is powered down during this passthrough operation.
The serial control bus supports the I2C protocol, whereas the serial audio data bus is programmable for I2S,
left/right-justified, DSP, or TDM modes. A highly programmable PLL is included for flexible clock generation and
support for all standard audio rates from a wide range of available MCLKs, varying from 512 kHz to 50 MHz,
with special attention paid to the most-popular cases of 12-MHz, 13-MHz, 16-MHz, 19.2-MHz, and 19.68-MHz
system clocks.
The TLV320AIC3104 operates from an analog supply of 2.7 V–3.6 V, a digital core supply of 1.525 V–1.95 V,
and a digital I/O supply of 1.1 V–3.6 V. The device is available in a 5-mm × 5-mm 32-pin QFN package.
