Description
PCM1862QDBTRQ1 is Texas Instruments’ automotive-grade, 24-bit stereo digital-to-analog converter (DAC). It converts digital audio data into two analog audio channels and supports standard digital interfaces (I2S, left-justified, DSP formats) with sampling rates up to 192 kHz. The device comes in an automotive-qualified QFN package (QDB) and carries the -Q1 automotive grade suffix. Features typically include low-noise, high-SNR DAC operation and a configurable control interface (I2C/SPI) for settings such as digital filter options, mute, and power modes. It’s suited for car audio, infotainment, and other compact audio applications requiring high-quality DAC performance in an automotive environment.
