Texas Instruments DAC0832LCN

Description
The DAC0830 is an advanced CMOS/Si-Cr 8-bit multiplying DAC designed to interface directly with popular microprocessors like the 8080, 8048, 8085, and Z80. It features a deposited silicon-chromium R-2R resistor ladder network for excellent temperature tracking characteristics and low linearity error over temperature. The circuit employs CMOS current switches and control logic for low power consumption and low output leakage current errors. Special circuitry ensures 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, enabling simultaneous updating of multiple DACs.
