DAC0832LCWM

Product Summary

The DAC0832LCWM is an advanced CMOS/Si-Cr 8-bit multiplying DAC. The DAC0832LCWM is designed to interface directly with the 8080, 8048, 8085, Z80 and other popular microprocessors. A deposited silicon-chromium R-2R resistor ladder network divides the reference current and provides the circuit with excellent temperature tracking characteristics (0.05% of Full Scale Range maximum linearity error over temperature). The DAC0832LCWM uses CMOS current switches and control logic to achieve low power consumption and low output leakage current errors. Special circuitry provides TTL logic input voltage level compatibility. Double buffering allows these DACs to output a voltage corresponding to one digital word while holding the next digital word. This permits the simultaneous updating of any number of DACs.
