Data Sheet FEATURES 16-bit resolution AD5543 14-bit resolution AD5553 ±1 LSB DNL ±1 LSB INL Low noise: 12 nV/√Hz Low power: IDD = 10 µA 0.5 µs settling time 4-quadrant multiplying reference input 2 mA full-scale current ± 20%, with VREF = 10 V Built-in RFB facilitates voltage conversion 3-wire interface Ultracompact 8-lead MSOP and 8-lead SOIC packages APPLICATIONS Automatic test equipment Instrumentation Digitally controlled calibration Industrial control programmable logic controllers GENERAL DESCRIPTION The AD5543/AD5553 are precision 16-/14-bit, low power, current output, small form factor digital-to-analog converters (DACs). They are designed to operate from a single 5 V supply with a ±10 V 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 microcontrollercompatible inputs using serial data in (SDI), clock (CLK), and chip select (CS). The AD5543/AD5553 are packaged in ultracompact (3 mm × 4.7 mm) 8-lead MSOP and 8-lead SOIC packages. Rev.
