DESCRIPTION
The PCM3060 is a low-cost, high-performance,
single-chip, 24-bit stereo audio codec with
single-ended analog inputs and differential analog
outputs.
The stereo 24-bit ADC employs a 64-times
delta-sigma modulator. It supports 16–96 kHz
sampling rates and a 16/24-bit digital audio output
word on the audio interface.
The stereo 24-bit DAC employs a 64- or 128-times
delta-sigma modulator. It supports 16–192 kHz
sampling rates and a 16/24-bit digital audio input
word on the audio interface.
The PCM3060 supports fully independent operation
of the sampling rate and audio interface for the ADC
and DAC.
Each audio interface supports I2S, left-justified, and
right-justified formats with 16/24-bit words.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
