The 16-bit current-output digital-to-analog converters designed to operate from a 4.5V to 5.5V supply range.
An external reference is needed to establish the full-scale output-current. An internal feedback resistor 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.
