TIPCM1681PWPR
Overview
The PCM1681PWPR is an 8-channel, 24-bit audio digital-to-analog converter (DAC) designed for high-performance multi-channel audio systems. It supports sampling rates up to 192kHz and features a flexible data interface compatible with I2S, Left-Justified, Right-Justified, and DSP formats. The device operates on a dual-supply architecture with 5V analog and 3V to 3.6V digital rails, providing high-quality audio output for surround sound and automotive infotainment applications.
Why Choose This Part
The PCM1681PWPR offers high integration with 8 channels in a single 28-HTSSOP package, reducing PCB footprint in multi-channel designs. It features an integrated power-on reset and 5V tolerant digital I/O for easier system integration with various microcontrollers. Additionally, the device includes an automatic system clock detection circuit that simplifies software configuration during sampling rate changes.
Applications
Key Specifications
Getting Started
To evaluate the PCM1681PWPR, engineers typically use an I2S source from a DSP or MCU like an STM32 or TI Tiva C series. Ensure the thermal pad of the HTSSOP package is properly soldered to a ground plane for heat dissipation and stable analog performance. Design the output stage with a low-pass filter to remove out-of-band noise, following the recommended active filter topologies in the datasheet.
