AD5545BRUZ

The AD5545BRUZ is a 16-bit current-output Digital-to-analog Converter (DAC) designed to operates from a 4.5 to 5.5V supply range. An external reference is needed to establish the full-scale output-current. An internal feedback resistor (RFB) enhances the resistance and temperature tracking when combined with an external op amp to complete the I-to-V conversion. A serial data interface offers high speed, 3-wire microcontroller compatible inputs using serial data in (SDI), clock (CLK) and chip select (CS). Additional LDAC function allows simultaneous update operation. The internal reset logic allows power-on preset and dynamic reset at either zero or midscale, depending on the state of the MSB pin.
