GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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

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:

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.

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.

The AD7541A uses laser wafer trimming to provide full 12-bit

endpoint linearity with several high performance grades.

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.
