AD5545BRUZ-REEL7

AD5545 is a 16-bit, current-output, digital to-analogue converter. It is 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 (RFB) enhances the resistance and temperature tracking when combined with an external opamp 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. It is widely used in application such as automatic test equipment, instrumentation, digitally controlled calibration, industrial control PLCs, programmable attenuator etc.
