AD5620CRM-2

The AD5620CRM-2, part of Analog Devices' nanoDAC family, is a high-performance, low-power, single 12-bit digital-to-analog converter (DAC). It offers a buffered voltage output and is guaranteed monotonic by design. This device incorporates an internal 1.25 V or 2.5 V reference with a temperature coefficient of 5 ppm/°C, providing a full-scale output voltage range of 2.5 V or 5 V respectively.

Key electrical specifications include a 12-bit resolution, a settling time of 10µs, and an integral nonlinearity (INL) of ±1 (Max). It operates from a single 3 V or 5 V power supply and features a serial interface supporting SPI and DSP protocols. The DAC output powers up to 0 V or midscale and remains there until a valid write occurs, thanks to its power-on reset circuit. For power-sensitive applications, a power-down feature reduces current consumption to as low as 480 nA at 5 V.

The AD5620CRM-2 is housed in an 8-lead MSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 105°C. This DAC is well-suited for applications such as process control, data acquisition systems, and portable battery-powered instruments where precise voltage output and low power consumption are critical.
