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.","metaTitle":"TI PCM1861DBT Audio ADC, 24-bit 192k, 30-TSSOP","metaDescription":"Texas Instruments PCM1861DBT audio ADC, 24-bit resolution, 192k sampling rate, 2-channel, I²C/SPI interface, -40 to 125°C, active, ROHS3.
