Quad 12-Bit Digital-to-Analog Converter Serial Interface
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 simultaneously 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°Cto +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.
