PCM3168A-Q1

SBAS452 – SEPTEMBER 2008 ......................................................................................................................................................................................... www.ti.com

The PCM3168A and PCM3168A-Q1 are high-performance, single-chip, 24-bit, 6-in/8-out, audio coders/decoders

(codecs) with single-ended and differential selectable analog inputs and differential outputs. The six-channel,

24-bit analog-to-digital converter (ADC) employs a delta-sigma (

ΔΣ) modulator and supports 8-kHz to 96-kHz

sampling rates and a 16-bit/24-bit width digital audio output word on the audio interface. The eight-channel,

24-bit digital-to-analog converter (DAC) employs a

ΔΣ modulator and supports 8-kHz to 192-kHz sampling rates

and a 16-bit/24-bit width digital audio input word on the audio interface. Each audio interface supports I2S,

left-justified, right-justified, and DSP formats with 16-bit/24-bit word width. In addition, the PCM3168A and

PCM3168A-Q1 support the time-division-multiplexed (TDM) format.

The PCM3168A and PCM3168A-Q1 can be controlled through a four-wire, SPI-compatible interface, or two-wire,

I2C-compatible serial interface in software, which provides access to all functions including digital attenuation,

soft mute, de-emphasis, and so forth. Also, hardware control mode provides a subset of user-programmable

functions through four control pins. The PCM3168A and PCM3168A-Q1 are available in a 12-mm × 12-mm

(10-mm × 10-mm body) HTQFP-64 PowerPAD™ package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
