16-Bit, Unbuffered Voltage Output DAC with SPI Interface Spec’d to +175°C

The AD5600 from Analog Devices is a single channel, 16-bit resolution, voltage output digital-to-analog converter (DAC) designed for high temperature operation. The AD5600 guarantees 16-bit monotonicity over the specified temperature range and operates from a single 2.7V to 5.5V voltage supply.

Targeted applications for the AD5600 include downhole drilling and instrumentation, heavy industrial equipment and other high temperature environments.

For space constrained applications, the AD5600 is available in a 10-lead MSOP with operation specified from −55°C to +175°C. This package is designed for robustness at extreme temperatures, including monometallic wire bonding, and is qualified for up to 1000 hours of operation at the maximum temperature rating.

The AD5600 uses a versatile 3-wire serial peripheral interface (SPI) that is compatible with 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards.
