PCM5102A stereo audio DAC with I2S and up to 32 bit resolution

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
PCM5102A is a high quality digital to analog converter DAC for stereo audio from Texas Instruments. The device converts digital audio data into an analog left and right audio signal that can be connected to an audio amplifier, active speaker or other audio equipment.

PCM5102A is designed for digital audio transmission using I2S and accepts 16, 24 and 32 bit audio data. Sample rates from 8 kHz up to 384 kHz are supported. The integrated PLL means that a separate Master Clock MCLK is normally not required, allowing a simple connection using three I2S signals: BCK, LRCK and DIN.

The DAC provides two analog outputs for the left and right channels. The integrated line driver provides a nominal output level of 2.1 VRMS and can drive loads down to 1 kohm. DirectPath technology provides a ground centered analog output and normally eliminates the need for external DC blocking capacitors at the output.

PCM5102A is well suited for audio projects using devices such as ESP32, Raspberry Pi and other microcontrollers or processors with I2S support. It can be used as the link between a digital audio source and a separate power stage, such as a class D amplifier.

The device also includes integrated muting, power saving, PLL and protection functions to help reduce clicks and noise during startup and shutdown. This makes it suitable for designs where good audio quality and simple digital audio connectivity are important.

Please note that PCM5102A is a DAC and line driver, not a power amplifier. It therefore cannot drive a standard passive speaker directly. The analog output is normally connected to a separate audio amplifier.
