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.
