AD5543BRMZ

AD5543 is a precision 16bit, low power, current output, small form factor digital-to-analogue converter (DAC). This is designed to operate from a single 5V supply with a ±10V multiplying reference. The applied external reference, VREF, determines the full-scale output current. An internal feedback resistor (RFB) facilitates the R-2R and temperature tracking for voltage conversion when combined with an external operational amplifier. A serial data interface offers high speed, 3-wire microcontroller compatible inputs using serial data in (SDI), clock (CLK), and chip select (active-low CS). Typical applications are automatic test equipment, instrumentation, digitally controlled calibration, industrial control programmable logic controllers.
