AD7541
12-Bit, Multiplying D/A Converter
File Number 3107.1
Features
• 12-Bit Linearity 0.01%
• Pretrimmed Gain
• Low Gain and Linearity Tempcos
• Full Temperature Range Operation
• Full Input Static Protection
• TTL/CMOS Compatible
• +5V to +15V Supply Range
• 20mW Low Power Dissipation
• Current Settling Time 1µs to 0.01% of FSR
• Four Quadrant Multiplication
Description
The AD7541 is a monolithic, low cost, high performance,
12-bit accurate, multiplying digital-to-analog converter
(DAC).
Intersil’ wafer level laser-trimmed thin-film resistors on
CMOS circuitry provide true 12-bit linearity with TTL/CMOS
compatible operation.
Special tabbed-resistor geometries (improving time stability),
full input protection from damage due to static discharge by
diode clamps to V+ and ground, large I
OUT1
and I
OUT2
bus
lines (improving superposition errors) are some of the fea-
tures offered by Intersil AD7541.
Pin compatible with AD7521, this DAC provides accurate
four quadrant multiplication over the full military temperature
range.
