MAX9943/MAX9944

High-Voltage, Precision, Low-Power Op Amps

General Description

The MAX9943/MAX9944 is a family of high-voltage

amplifiers that offers precision, low drift, and low-power

consumption.

The MAX9943 (single) and MAX9944 (dual) op amps

offer 2.4MHz of gain-bandwidth product with only 550μA

of supply current per amplifier.

The MAX9943/MAX9944 family has a wide power supply

range operating from ±3V to ±19V dual supplies or a 6V

to 38V single supply.

The MAX9943/MAX9944 is ideal for sensor signal condi-

tioning, high-performance industrial instrumentation and

loop-powered systems (e.g., 4mA–20mA transmitters).

The MAX9943 is offered in a space-saving 6-pin TDFN

or 8-pin μMAX® package. The MAX9944 is offered in an

8-pin SO or an 8-pin TDFN package. These devices are

specified over the -40°C to +125°C automotive tempera-

ture range.
