Product Details

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 are ideal for sensor signal conditioning, 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 temperature range.
