GENERAL DESCRIPTION

BIT 12 (LSB)

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.

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 µA maximum input current

requirement so as not to load the driving circuitry.

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.

Improvements: The AD7541A offers the following improved

specifications over the AD7541:

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

endpoint linearity with several new high performance grades.

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

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

differential nonlinearity for top grade devices over the operat-

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

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

operating temperature range.
