GENERAL DESCRIPTION

The Analog Devices AD7541A is a low cost, high performance

12-bit monolithic multiplying digital-to-analog converter. It is

fabricated using advanced, low noise, thin film on CMOS

technology and is available in a standard 18-lead DIP and in

20-terminal surface mount packages.

The AD7541A is functionally and pin compatible with the in-

dustry standard AD7541 device and offers improved specifica-

tions and performance. The improved design ensures that the

device is latch-up free so no output protection Schottky diodes

are required.

This new device uses laser wafer trimming to provide full 12-bit

endpoint linearity with several new high performance grades.

PRODUCT HIGHLIGHTS

Compatibility: The AD7541A can be used as a direct replace-

ment for any AD7541-type device. As with the Analog Devices

AD7541, the digital inputs are TTL/CMOS compatible and

have been designed to have a 1 A maximum input current

requirement so as not to load the driving circuitry.

Improvements: The AD7541A offers the following improved

specifications over the AD7541:

1. Gain Error for all grades has been reduced with premium

2. Gain Error temperature coefficient has been reduced to

3. Digital-to-analog charge injection energy for this new device

4. Latch-up proof.

5. Improvements in laser wafer trimming provides 1/2 LSB max

6. All grades are guaranteed monotonic to 12 bits over the

grade versions having a maximum gain error of 3 LSB.

2 ppm/ C typical and 5 ppm/ C maximum.

ing temperature range (vs. 1 LSB on older 7541 types).
