AD5541JRZ

AD5541JRZ is a 12-bit multiplying digital-to-analog converter (MDAC) from Analog Devices. It uses a serial (SPI-like) interface to load a 12-bit input word, and its output is a current proportional to the product of the input code and an external reference. The resulting Iout can be converted to voltage with an external op-amp and feedback resistor. This makes it suitable for precision applications such as waveform generation, calibration, programmable gain, and control loops. The device is designed for good monotonicity and stability over typical industrial temperatures. The JRZ suffix indicates a RoHS-compliant package (typically an 8-pin package). It requires an external reference and an I/V conversion stage, with full-scale current set by the reference and external network. For exact specs (supply range, Iout range, timing, and data format), refer to the latest AD5541 datasheet or product page.

Key features of AD5541JRZ (12‑bit multiplying DAC):
- 12-bit multiplying DAC (M‑DAC) for precise scaling with an external reference
- SPI-compatible serial input interface for straightforward digital control
- Output scale set by Vref; suitable for unipolar or bipolar output configurations
- Monotonic operation with low glitch, good linearity (DNL/INL within datasheet limits)
- Fast settling and stable accuracy for waveform generation and control loops
- Low power consumption; suitable for portable/instrumentation apps
- Industrial temperature range (robust performance over -40°C to +85°C)
- Small/compact package (JRZ family) for dense board layouts
Notes:
- External reference required to define full-scale.
- Output typically requires external buffering/op-amp for voltage conversion (depending on configuration).

- Pin count: 16 pins (JRZ package, RoHS-compliant SOIC-16/DIP-16 variant)
- Function: 12‑bit, single‑channel multiplying DAC with a serial SPI‑like interface. Converts a serial data word into a voltage output (VOUT) using an external reference; includes control inputs such as CS, SCLK, DIN, LDAC, CLR; requires VDD and GND (and VREF).
