Description
The AD5322ARMZ is a dual-channel, 12-bit digital-to-analog converter (DAC) from Analog Devices. It operates with a 2.5V to 5.5V supply, making it suitable for low-power applications. Key features include:
- Dual 12-bit DACs with rail-to-rail output buffers.
- SPI-compatible serial interface (up to 50 MHz).
- Low power consumption (0.5 mA at 3V).
- On-chip reference (2.5V) or external reference support.
- Small 10-lead MSOP package (AD5322ARMZ).
Applications include industrial control, portable instrumentation, and automated test equipment. The device ensures monotonicity and offers power-on reset to zero/midscale.
