Overview
The DAC0832LCN/NOPB is an 8-bit microprocessor-compatible, double-buffered digital-to-analog converter (DAC) produced by Texas Instruments. This component is part of the DAC0830 series and is designed to interface directly with popular microprocessors such as the 8080, 8048, 8085, and Z80. The DAC0832LCN/NOPB features a CMOS/Si-Cr R-2R resistor ladder network, which provides excellent temperature tracking characteristics and low power consumption.
Although the DAC0832LCN/NOPB is currently obsolete and no longer manufactured, it remains a significant component in legacy systems and can be substituted with similar models like the TLC7524CN.
