12-Bit CMOS Multiplying D/A Converter

AD7541 Is Capable of Low-Feedthrough 4-Quadrant Operation; Monolithic IC is Laser Wafer-Trimmed for 12-Bit Linearity

The AD7541 is a low-cost 12-bit CMOS multiplying digital-to-analog converter housed in a standard 18-pin dual in-line package. Pin-compatible with the earlier AD7521, the AD7541 is the first such device to be laser-trimmed at the wafer stage (LWT) for less than 0.01% conversion nonlinearity (AD7541K/B/T); its thin-film resistors impart comparable linearity in response to positive or negative analog ("reference") signals. Read full article
