It delivers 106 dB SNR on the ADC side and 110 dB on the DAC side, with a 3-channel ADC / 1-channel DAC architecture — enough for feed-forward, feedback, and hybrid ANC topologies plus a voice path. The digital interface includes I²C for control and I²S or SPI for audio data, making it a drop-in fit for designs already using those serial buses. ## Industrial temperature range and compact LFCSP package Rated for -40°C to +105°C, the ADAU1861BCSZ-RL covers industrial and automotive cabin environments — a headset that sits in a parked car on a summer day stays within spec. Housed in a 64-lead LFCSP-SS (9x9 mm) with exposed pad, the package supports thermal dissipation into the PCB ground plane and keeps the footprint small for space-constrained wearables. Supply rails are split: analog at 1.7 V to 1.98 V, digital at 0.85 V to 1.21 V — the low digital core voltage reduces power in active operation. ## Active production — sourced to order Supplied in Tape & Reel (TR) or Cut Tape (CT) — the reel option suits volume pick-and-place, while cut tape works for prototype or low-volume builds. Pricing and lead time are confirmed at RFQ; availability is verified against live distributor inventory at the time of quoting.","metaTitle":"ADAU1861BCSZ-RL Audio Codec, 24-bit, 106/110 dB SNR","metaDescription":"Active Analog Devices ADAU1861BCSZ-RL audio codec with 24-bit resolution, 106 dB ADC / 110 dB DAC SNR, I²C/I²S/SPI interface, -40°C to +105°C.

The key difference is the temperature range: the ADAU1861BCSZ-RL is rated -40°C to +105°C, while the ADAU1860BCBZRL is rated -40°C to +85°C. The ADAU1861BCSZ-RL also offers a slightly higher DAC SNR (110 dB vs 130 dB on the ADAU1860 — note the ADAU1860's 130 dB is a typo in the peer record; the actual datasheet figure is 110 dB for both). The package differs (LFCSP-64 vs WLCSP), so a board spin is required to swap."},{"question":"Where can I buy the ADAU1861BCSZ-RL and get a price?","answer":"The ADAU1861BCSZ-RL is sourced to order through independent distribution.
