DESCRIPTION

7 × 7 mm 48-QFN

The TLV320AIC33 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 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 TLV320AIC33 contains

integrated microphone bias, digitally controlled stereo

microphone preamplifier, and automatic gain control

(AGC), with mix/mux capability among the multiple

analog inputs. The playback path includes mix/mux

capability from the stereo DAC and selected inputs,

through programmable volume controls, to the

various outputs.

The TLV320AIC33 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-Ω headphones using ac-coupling capacitors, or stereo 16-Ω headphones in

a capacitorless output configuration. In addition, pairs

of drivers can be used to drive 8-Ω speakers in a BTL

configuration at 500 mW per channel.

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 providing up to +59.5-dB analog gain for low-level microphone inputs.

The serial control bus supports SPI or I2C protocols,

while 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.
