Overview
The DAC0832LCWMX is an advanced 8-bit microprocessor-compatible, double-buffered digital-to-analog converter (DAC) produced by Texas Instruments. This component is designed to interface directly with popular microprocessors such as the 8080, 8048, 8085, and Z80. It features a CMOS/Si-Cr multiplying DAC architecture, which includes a deposited silicon-chromium R-2R resistor ladder network for excellent temperature tracking characteristics. The DAC0832LCWMX is known for its low power consumption, low output leakage current, and compatibility with TTL logic input voltage levels.
