Overview
The AD390TD, manufactured by Analog Devices Inc., is a quad 12-bit microprocessor-compatible digital-to-analog converter (DAC). This component is designed to provide high-speed voltage output and is packaged in a compact 28-pin hybrid or ceramic dual in-line package (CDIP). The AD390TD is based on a proprietary latched 12-bit DAC chip, which enhances reliability and reduces the overall chip count. It is ideal for systems that require digital control of multiple analog voltages, particularly where board space is limited.
