概要
Description
AD5426YRMZ is Analog Devices’ serial-input, current-output DAC. It’s part of the AD542x family and converts a digital word received over an SPI‑style interface into a programmable output current (Iout) used to drive industrial current loops and analog signaling. The YRMZ suffix denotes a RoHS-compliant, lead‑free LFCSP package variant.
Typical applications: industrial automation, process control, instrumentation, and motor control where a precise, monotonic current output is required.
Key features (typical): monotonic 12‑ to 16‑bit resolution, programmable full‑scale current, fast settling, low glitch energy, and options for internal or external references. It requires an external current‑to‑voltage conversion stage (precision resistor) to produce a voltage output.
For exact specifications (resolution, Iout range, interface timing, supply and temperature ranges), consult the latest AD5426 datasheet and application notes. If you need, I can pull out the specific figures.

Pinout
8 pins. AD5426YRMZ is an 8‑pin MSOP device that functions as a single‑channel, serial‑input (SPI‑like) multiplying DAC with a current output (Iout). It uses a digital input interface (CS, SCK, DIN/SDI, LDAC) to set a coded output current proportional to the reference (Vref) and code. Typical pins include VDD, GND, IOUT, and VREF/REFIN.
