Dual 12-Bit CMOS DAC with Parallel Load Input Structure

Description

The AD7547 contains two 12-bit current output DACs on one monolithic chip. Also on-chip are the level shifters, data registers and control logic for easy microprocessor interfacing. There are 12 data inputs.CSA,CSB,WRcontrol DAC selection and loading. Data is latched into the DAC registers on the rising edge of WR. The device is speed compatible with most microprocessors and accepts TTL, 74HC and 5V CMOS logic level inputs.The D/A converters provide 4-quadrant multiplication capabilities with separate reference inputs and feedback resistors. Monolithic construction ensures that thermal and gain error tracking is excellent. 12-bit monotonicity is guaranteed for both DACs over the full temperature range.The AD7547 is manufactured using the Linear Compatible CMOS (LC2MOS) process. This allows fast digital logic and precision linear circuitry to be fabricated on the same die.APPLICATIONSAutomatic Test EquipmentProgrammable FiltersAudio ApplicationsSynchro ApplicationsProcess Control
