Product details

The AD5421BCPZ-REEL7 is a 16-bit, single-channel, current-output DAC from Analog Devices, built on a Cyclic Serial architecture. 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.

Frequently asked questions

What is the typical application of AD5421BCPZ-REEL7?

This 16-bit current-output DAC is designed for industrial control loops, 4–20 mA transmitters, actuator drives, and precision instrumentation requiring a buffered current signal. The Cyclic Serial architecture and SPI/DSP interface suit it for PLC analog output modules and sensor transmitter boards.

How does AD5421BCPZ-REEL7 compare to AD5420?

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.
