It has 2 channels, so it handles stereo line-level inputs directly. The data interface is I²C or SPI, which means you can talk to it from most microcontrollers without needing a dedicated audio codec bus — useful for embedded systems where the MCU already has those peripherals. ## Supply and temperature range The supply source is both analog and digital, so you need separate clean rails for the analog front-end and the digital core — typical for audio ADCs to keep switching noise out of the signal path. It comes in a 30-TFSOP package (0.173\" wide, 4.40 mm width), also referred to as 30-TSSOP. Surface-mount, so it sits flat on the board — the 0.65 mm pitch is fine for hand-assembly with a decent iron and flux, but reflow is cleaner for production. Available in Tape & Reel (TR) or Cut Tape (CT) — the reel option is for pick-and-place; cut tape works for prototypes or small runs.","metaTitle":"TI PCM1861DBTR Audio ADC, 24-bit 192k, 30-TSSOP","metaDescription":"Texas Instruments PCM1861DBTR audio ADC, 24-bit resolution, 192k sampling rate, I²C/SPI interface, -40°C to 125°C, 30-TSSOP.
