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

Product Details

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, 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 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.

Tools & Simulations

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
