Features and Benefits

  • Improved version of the obsoleted product, AD7541
  • Full 4 quadrant multiplication
  • 12-bit linearity (endpoint)
  • All parts guaranteed monotonic
  • TTL/CMOS compatible
  • Protection Schottky diodes not required
  • Low logic input leakage

Product Details

The AD7541A is a high performance, 12-bit monolithic multiplying digital-to-analog converter (DAC). It is fabricated using advanced, low noise, thin film, complementary metal-oxide semiconductor (CMOS) technology. The AD7541A is available in 18-lead PDIP, 18-lead PLCC, and 18-lead SOIC packages.

The AD7541A is functionally and pin compatible with the industry standard AD7541, and it offers improved specifications and performance over the obsolete product, AD7541. The improved design ensures that the AD7541A is latch-up free; therefore, no output protection Schottky diodes are required.

The AD7541A uses laser wafer trimming to provide full 12-bit endpoint linearity with several high performance grades.

Product Highlights

Compatibility—The AD7541A can be used as a direct replacement for any AD7541 type device. As with the AD7541, The digital inputs on the AD7541A are TTL/CMOS compatible. They have a ±1 μA maximum input current requirement so that they do not load the driving circuitry.

Improvements—The AD7541A offers the following improved specifications over the AD7541:

  1. Gain error for all grades are reduced with premium grade versions having a maximum gain error of ±3 LSB.
  2. Gain error temperature coefficient are reduced to 2 ppm/°C typical and 5 ppm/°C maximum.
  3. Digital-to-analog charge injection energy for the AD7541A is typically 20% less than the standard AD7541.
  4. Latch-up proof.
  5. Laser wafer trimming provides 1/2 LSB maximum differential nonlinearity for top grade devices over the operating temperature range (vs. 1 LSB on previous AD7541 devices).
  6. All grades are guaranteed monotonic to 12 bits over the operating temperature range.

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.
