AD7247KN

The AD7247KN 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.

Both parts are microprocessor compatible,with high speed data latches and interface logic.The AD7247KN 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.A REF OUT/REF IN function is provided which allows eighter the on-chip 5V reference or external reference to be used as a reference voltage for the part.For single supply operation,two output range of 0 to +5V and 0 to +10V are available,while these two range plus an additional ±5 V range are available with dual supplies.The output amplifiers are capable of developing +10V across a 2 k load to GND.The AD7247KN is fabricated in Linear compatible CMOS (LC2MOS),an advanced,mixed technology process that combines precision bipolar circuits with low power CMOS logic.Both parts are available in a 24-pin,0.3" wide plastic and hermetic dual-in-line package (DIP) and are also package in a 24-lead small outline (SOIC) package.
