Description

The DAC4814 is one in a family of dual and quad 12- bit digital-to-analog converters. Serial, 8-bit, 12-bit interfaces are available.

The DAC4814 is complete. It contains CMOS logic, switches, a high-performance buried-zener reference, and low-noise bipolar output amplifiers. No external components are required for either unipolar 0 to 10V, 0 to 10V, or bipolar ±10V output ranges.

The DAC4814 has a high-speed serial interface capable of being clocked at 10MHz. Serial data are clocked DAC D MSB first into a 48-bit shift register, then strobed into each DAC separately or simulta- neously as required. The DAC has an asynchronous clear control for reset to unipolar or bipolar zero depending on the mode selected. This feature is useful for power-on reset or system calibration. The DAC4814 is packaged in a 28-pin plastic DIP rated for the 40°C to +85°C extended industrial temperature range.

High-stability laser-trimmed thin film resistors assure high reliability and true 12-bit integral and differential linearity over the full specified temperature range.
