16-bit audio DAC for PCM playback chains
The AD1856R-REEL is a single-channel 16-bit PCM audio DAC from Analog Devices, designed for digital audio playback in consumer and pro-audio gear. Its serial data interface and dual ± supply rails (4.75 V to 13.2 V on each side) fit into traditional audio DAC signal chains where the analog stage runs on bipolar rails.
Package, temp grade, and supply reality
Housed in a 16-SOIC wide-body (0.295", 7.50 mm width) surface-mount package, the AD1856R-REEL is supplied in bulk tube — not tape-and-reel, so plan for manual or tube-fed pick-and-place. The operating temperature range is -25°C to 70°C, which covers most indoor audio equipment but not automotive or extended industrial environments. Supply voltage source is dual ±, meaning the part needs both a positive and a negative rail — common in older audio DAC designs but worth confirming your board has the negative supply before specifying this into a single-supply system.
Sourcing and cross-reference note
For a pin-compatible alternative in the same package, the AD1856R-K shares the same 16-SOIC footprint, single-channel, serial interface, and dual ± supply — a direct drop-in for boards already laid out for the AD1856R family.
