DAC7802KU General Description

The DAC7800,DAC7801 and DAC7802 are members of a new family of monolithic dual 12-bit CMOS multiplying Digital-to-Analog Converters (DACs). The 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°C 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 (edge triggered) 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. It is packaged in a 16-pin 0.3" wide plastic DIP.

The DAC7801 has a 2-byte (8 + 4) double-buffered interface. Data is first loaded (level transferred) into the input registers in two steps for each DAC. Then both DACs are updated simultaneously. The DAC7801 features an asynchronous CLEAR control. The DAC7801 is packaged in a 24-pin 0.3" wide plastic DIP. The DAC7802 has a single-buffered 12-bit data word interface. Parallel data is loaded (edge triggered) into the single DAC register for each DAC. The DAC7802 is packaged in a 24-pin 0.3" wide plastic DIP.
