AD7541

12-Bit, Multiplying D/A Converter

August 1997

Features

Description

• 12-Bit Linearity 0.01%

The AD7541 is a monolithic, low cost, high performance,

12-bit accurate, multiplying digital-to-analog converter

(DAC).

• Pretrimmed Gain

• Low Gain and Linearity Tempcos

• Full Temperature Range Operation

• Full Input Static Protection

• TTL/CMOS Compatible

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

lines (improving superposition errors) are some of the fea-

tures offered by Intersil AD7541.

and I

bus

• +5V to +15V Supply Range

• 20mW Low Power Dissipation

• Current Settling Time 1µs to 0.01% of FSR

• Four Quadrant Multiplication

OUT1

OUT2

Pin compatible with AD7521, this DAC provides accurate

four quadrant multiplication over the full military temperature

range.
