AD5553CRM

电流输出/串行输入， 16位/ 14位DAC Current Output/ Serial Input, 16-/14-Bit DAC

Product Details

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 op amp.

A serial-data interface offers high speed, 3-wire microcontroller-compatible inputs using serial data in SDI, clock CLK, and chip select CS.

The AD5543/AD5553 are packaged in ultracompact 3 mm × 4.7 mm MSOP-8 and SOIC-8 packages.
