DAC8248FPZ Datasheet PDF - ADI

●The DAC8248FPZ is a dual 12-bit double-buffered CMOS Digital-to-analog Converter has a 8-bit wide input data port that interfaces directly with 8-bit microprocessors. It loads a 12-bit word in two bytes using a single control; it can accept either a least significant byte or most significant byte first. The DAC8248 double-buffered digital inputs allow DAC analog output to be updated simultaneously. This particularly useful in multiple DAC systems where a common LDAC signal updates DAC at the same time. A single RESET pin resets both outputs to zero. The DAC8248 monolithic construction offers excellent DAC-to-DAC matching and tracking over the full operating temperature range. The DAC consists of two thin-film R-2R resistor ladder networks, two 12-bit, two 8-bit and two 4-bit data registers and control logic circuitry. Separate reference input and feedback resistors are provided for DAC.
