It digitizes four analog audio channels at sampling rates from 32 kHz to 192 kHz, covering everything from voice-band to high-definition audio capture. The digital output goes over I²C or SPI, so it ties directly into a host processor's serial bus without an external codec interface. The 3.3 V supply rail powers both the analog and digital sections from a single source. 32-bit resolution means the ADC captures a theoretical dynamic range of about 192 dB — enough headroom for automotive cabin audio, active noise cancellation, or microphone arrays where the quietest signal sits far below the loudest peak. The 4-channel count lets one IC handle a stereo pair plus two auxiliary inputs, saving board space versus multiple dual-channel ADCs. The -40°C to 125°C operating range is the full automotive temperature grade (AEC-Q100 Grade 1). That means it lives in the engine bay or on a dashboard that bakes in summer sun — no derating needed for under-hood ambient.","metaTitle":"TI PCM1864QDBTRQ1 Audio ADC, 32-bit, 4-ch, AEC-Q100","metaDescription":"Texas Instruments PCM1864QDBTRQ1 32-bit audio ADC, 4-channel, 192k sampling, I2C/SPI, -40 to 125°C, AEC-Q100.
