The AD5348BRUZ is an octal 12-bit Digital-to-analog Converter (DAC) operating from a 2.5 to 5.5V supply. This device incorporates an on-chip output buffer that can drive the output to both supply rails. It has a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. A read-back feature allows the internal DAC registers to be read back through the digital port. An asynchronous CLR input is also provided, which resets the contents of the input register and the DAC register to all zeros. This device also incorporates a power-on reset circuit that ensures that the DAC output powers on to 0V and remains there until valid data is written to the device. It is pin compatible, which allows users to select the amount of resolution appropriate for its application without redesigning its circuit board.
- Input data to the DAC is double-buffered
- Guaranteed monotonic by design over all codes
- Simultaneous update of DAC outputs via LDAC pin
- Asynchronous CLR facility
