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. H Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
