TLV320AIC3106

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.
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 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 TLV320AIC3106 provides an extremely high range of programmability for both attack (8
ms – 1,408 ms) and for decay (0.05 s – 22.4 s). 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 passthru mode. This mode significantly reduces power consumption, as most of the
device is powered down during this pass through operation.
The serial control bus supports SPI or I
2
C protocols, while the serial audio data bus is programmable for I
2
S,
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 TLV320AIC3106 operates from an analog supply of 2.7 V – 3.6 V, a digital core supply of 1.65 V – 1.95 V, and
a digital I/O supply of 1.1 V – 3.6 V. The device is available in the 5-mm × 5-mm, 80-ball MicroStar Junior™ BGA
package and a 7-mm × 7-mm, 48-lead QFN package.
