PCM1754-Q1 - Automotive Catalog 106dB SNR Stereo Audio DAC (H/W Control)

The PCM175x-Q1 family of devices is a CMOS, monolithic, integrated circuit, which includes stereo digital-to-analog converters and support circuitry in a small 16-lead SSOP package. The data converters use TI's enhanced multilevel delta-sigma architecture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM175x-Q1 family of devices accepts industry-standard audio data formats with 16- to 24-bit data, providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 200 kHz are supported. A full set of user-programmable functions is accessible through a three-wire serial control port, which supports register write functions.

The PCM1753-Q1 device is pin-compatible with the PCM1748, PCM1742, and PCM1741 devices, except for pin 5.

For all available packages, see the orderable addendum at the end of the data sheet.
