AD7237KR

The AD7237KR is a complete dual 12-bit digital-to-analog converter (DAC) from Analog Devices. It integrates two 12-bit CMOS DACs with output amplifiers and a voltage reference on a single chip. The device provides voltage-buffered outputs and uses an R-2R architecture. It features a parallel data interface for easy connection to microprocessors. Key electrical specifications include a settling time of 10 µs, integral nonlinearity (INL) of ±0.5 LSB maximum, and differential nonlinearity (DNL) of ±0.9 LSB maximum. The reference type is external or internal. The operating temperature range is -40°C to +85°C. The AD7237KR is supplied in a 24-SOIC surface-mount package (0.295" width, 7.50mm). It requires a dual ±15V supply. This DAC is suitable for applications requiring two precise analog outputs from digital inputs, such as industrial control, instrumentation, and automatic test equipment. The surface-mount package allows for compact PCB designs.
