Product details

8-channel audio DAC with 192 kHz sampling

The PCM1681PWPR is an 8-channel audio digital-to-analog converter from Texas Instruments, delivering 24-bit resolution at sampling rates up to 192k per second.

Dual supply rails and industrial temperature range

The device operates from two supply domains: a 3V to 3.6V digital rail and a 5V analog rail, with separate supply source pins for analog and digital sections to keep digital switching noise out of the audio path.

28-HTSSOP package with exposed thermal pad

The supplier device package is 28-HTSSOP, identical to the 28-PowerTSSOP footprint.

Frequently asked questions

What is the PCM1681PWPR's data interface and sampling rate?

The PCM1681PWPR accepts audio data through a DSP or I²S serial interface and supports sampling rates up to 192 kHz with 24-bit resolution. The eight channels can carry independent audio streams or be paired for stereo outputs.

What supply voltages does the PCM1681PWPR require?

It needs two supply rails: a 3V to 3.6V digital supply and a 5V analog supply. The analog and digital sections have separate supply pins to isolate the sensitive audio path from digital switching noise.
