AD7547LPZ-REEL

DAC 2CH R-2R 12Bit 28Pin PLCC T/R

Product Details

The AD7547 contains two 12-bit current outpput 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, WR control 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 convereters provide 4-quadrant multiplication capabilities with seperate 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.
