APPLICATIONS Downhole drilling and instrumentation Heavy industrial High temperature environments GENERAL DESCRIPTION The AD5600 is a single channel, 16-bit resolution, voltage The AD5600 is a member of a growing series of high temperature output digital-to-analog converter (DAC) designed for high qualified products offered by Analog Devices, Inc. For a temperature operation. complete selection of available high temperature products, see the high temperature product list and qualification data The AD5600 guarantees 16-bit monotonicity over the specified available at www.analog.com/hightemp. temperature range and operates from a single 2.7 V to 5.5 V voltage supply. PRODUCT HIGHLIGHTS For space constrained applications, the AD5600 is available in a 1. 16-bit monotonic DAC 10-lead MSOP with operation specified from 55C to +175C. 2. 2.7 V to 5.5 V single-supply operation This package is designed for robustness at extreme temperatures, 3. 1.8 V logic compatible including monometallic wire bonding, and is qualified for up to 4. Wide operating temperature range: 55C to +175C 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. Rev.
