Product Summary

The AD7237KN is a complete, dual, 12-bit. voltage output digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. The AD7237KN is microprocessor compatible, with high speed data latches and interface logic. The AD7237KN accepts 12-bit parallel data which is loaded into the respective DAC latch using the WR input and a separate Chip Select input for each DAC.
