Reference Multiplying Bandwidth GENERAL DESCRIPTION The AD5543/AD5553 are precision 16-/14-bit, low power, current output, small form factor digital-to-analog converters. 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. |
