DAC7800KU

The DAC7800KU is a monolithic dual 12-bit CMOS multiplying Digital-to-analog Converter (DAC) with digital interface speed and the AC multiplying performance are achieved by using an advanced CMOS process optimized for data conversion circuits. High stability on-chip resistors provide true 12-bit integral and differential linearity over the wide industrial temperature range of -40 to 85°C. The DAC7800 features a serial interface capable of clocking-in data at a rate of at least 10MHz. Serial data is clocked MSB first into a 24-bit shift register and then latched into each DAC separately or simultaneously as required by the application. An asynchronous CLEAR control is provided for power-on reset or system calibration functions. The DAC7801 has a 2-byte double-buffered interface. Data is first loaded into the input registers in two steps for each DAC. Then the DAC is updated simultaneously. The DAC7801 features an asynchronous CLEAR control.
