Product details

24-bit, 192 kHz audio ADC in 30-TSSOP

The PCM1861DBT is a 24-bit audio ADC from Texas Instruments, sampling at 192k samples per second across two channels.

Digital interface and signal chain fit

Data is read out over either I²C or SPI — the dual-interface flexibility lets the ADC drop into existing bus architectures without a protocol translator. Sampling at 192 kHz with 24-bit resolution means the PCM1861DBT captures the full audible band plus ultrasonic content for applications like acoustic leak detection or active noise cancellation reference microphones.
