It delivers a buffered current output with a typical settling time of 50µs. ## Temperature range and environment Rated for -40°C to 105°C, this DAC fits industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules that see thermal cycling. The surface-mount LFCSP package is board-level compatible with standard reflow profiles; no special handling beyond normal moisture-sensitive-device precautions.","metaTitle":"AD5421BCPZ-REEL7 16-Bit Current-Output DAC, 32-LFCSP","metaDescription":"AD5421BCPZ-REEL7 16-bit current-output DAC from Analog Devices.

The Cyclic Serial architecture and SPI/DSP interface suit it for PLC analog output modules and sensor transmitter boards."},{"question":"How does AD5421BCPZ-REEL7 compare to AD5420?","answer":"The AD5421 is a 16-bit current-output DAC with Cyclic Serial architecture, while the AD5420 is a 16-bit voltage- or current-output DAC using an R-2R architecture. The AD5421's settling time is 50µs typical; the AD5420's is faster at 25µs (voltage) and 40µs (current). The AD5421 operates from a lower analog supply range (1.71V–5.5V) versus the AD5420's 10.8V supply. Both share the same SPI/DSP interface and -40°C to 105°C temperature range. Choose the AD5421 for lower-voltage, current-only designs; the AD5420 for dual voltage/current output with faster settling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD5421BCPZ-REEL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD5421BCPZ-REEL7 when reusing this data.
