Description
AD5142ABRUZ10-RL7 is a dual 12-bit multiplying digital-to-analog converter (MDAC) from Analog Devices. The AD5142 family provides two independent DAC channels with multiplying capability, so each output scales with an external reference. It uses a serial interface (SPI‑like) for data input and control, making it suitable for programmable gain, calibration, waveform generation, and closed-loop control.
Key points:
- 12-bit resolution per channel; multiplying architecture
- SPI-compatible serial interface
- Typically operates on a single 2.7–5.5 V supply; precision and drift characteristics depend on the exact variant
- Output can be used as a voltage output (with proper reference/op-amp) or a current/LDAC-configured output, per application
The suffix ABRUZ10-RL7 encodes device grade/package/reel options (industrial/rohs and a specific packaging). For exact electrical specs, timing, and recommended external components, refer to the latest ADI data sheet for AD5142.
