Features and Benefits
- Two 12-bit DACs in One Package
- DAC Ladder Resistance Matching: 0.5%
- Space Saving Skinny DIP and Suface Mount Packages
- 4-Quadrant Multiplication
- Low Gain Error (1 LSB max Over Temperature)
- Fast Interface Timing
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.

Application Notes (8)
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
