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
grade versions having a maximum gain error of
±3 LSB.
2. Gain Error temperature coefficient has been reduced to
2 ppm/
°C typical and 5 ppm/°C maximum.
3. Digital-to-analog charge injection energy for this new device
is typically 20% less than the standard AD7541 part.
4. Latch-up proof.
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.
