The DAC2814 is one in a family of dual and quad 12-bit digital-to-analog converters. Serial, 8-bit, 12-bitinterfaces are available.The DAC2814 is complete. It contains CMOS logic,switches, a high-performance buried-zener reference,and low-noise bipolar output amplifiers. No externalcomponents are required for either unipolar 0 to 10V,0 to –10V, or bipolar ±10V output ranges.The DAC2814 has a high-speed serial interfacecapable of being clocked at 10MHz. Serial data areclocked DAC B MSB first into a 24-bit shift register,then strobed into each DAC separately or simultaneouslyas required. The DAC has an asynchronousclear control for reset to unipolar or bipolar zerodepending on the mode selected. This feature is usefulfor power-on reset or system calibraTIon. The DAC2814is packaged in a 24-pin plasTIc DIP rated for the –40°Cto +85°C extended industrial temperature range.High-stability laser-trimmed thin film resistors assurehigh reliability and true 12-bit integral and differenTIallinearity over the full specified temperature range.
