Low-Power Stereo CODEC With 6 Inputs, 7 Outputs, HP/Speaker Amplifier And 3D Effects

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 1576 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- Headphones using ac-coupling capacitors, or stereo 16- Headphones in a capacitorless output configuration. In addition, pairs of drivers CAN be used to drive 8- 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
The TLV320AIC33 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 5 5-mm, 80-ball MicroStar Junior? BGA and 7 7-mm, 48-lead QFN.
