GENERAL DESCRIPTION

BIT 3  
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.

ITS DIGITAL INPUT IN A "HIGH" STATE.  
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

grade versions having a maximum gain error of ±3 LSB.  
2. Gain Error temperature coefficient has been reduced to

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).
