AD7247ABR-REEL FEATURES

Complete Dual 12-Bit DAC ComprisingTwo 12-Bit CMOS DACs

AD7247ABR-REEL GENERAL DESCRIPTION

The AD7237A/AD7247A is an enhanced version of the industrystandard AD7237/AD7247. Improvements include operationfrom 12 V to 15 V supplies, faster interface times and betterreference variations with VDD. Additional features include fastersettling times.The AD7237A/AD7247A is a complete, dual, 12-bit, voltageoutput digital-to-analog converter with output amplifiers andZener voltage reference on a monolithic CMOS chip. No exter-nal user trims are required to achieve full specified performance.Both parts are microprocessor compatible, with high speed datalatches and interface logic. The AD7247A accepts 12-bit paral-lel data which is loaded into the respective DAC latch using theWR input and a separate Chip Select input for each DAC. TheAD7237A has a double buffered interface structure and an 8-bitwide data bus with data loaded to the respective input latch intwo write operations. An asynchronous LDAC signal on theAD7237A updates the DAC latches and analog outputs.A REF OUT/REF IN function is provided which allows eitherthe on-chip 5 V reference or an external reference to be used asa reference voltage for the part. For single supply operation, twooutput ranges of 0 V to +5 V and 0 V to +10 V are available,while these two ranges plus an additional ±5 V range are avail-able with dual supplies. The output amplifiers are capable of de-veloping +10 V across a 2 kΩ load to GND.The AD7237A/AD7247A is fabricated in Linear CompatibleCMOS (LC2MOS), an advanced, mixed technology processthat combines precision bipolar circuits with low power CMOSlogic. Both parts are available in a 24-pin, 0.3" wide plastic andhermetic dual-in-line package (DIP) and are also packaged in a24-lead small outline (SOIC) package.
