Overview
The AD7243BR, manufactured by Analog Devices Inc., is a complete 12-bit, voltage output, digital-to-analog converter (DAC) integrated on a single monolithic CMOS chip. This device features an on-chip voltage reference and an output amplifier, eliminating the need for external trims to achieve full specified performance. The AD7243BR is designed for high reliability and is fabricated using Linear Compatible CMOS (LC2MOS) technology, an advanced mixed technology process. It is available in 16-lead DIP and 16-lead SOIC packages.
