Improve System Accuracy for High-Voltage

Applications in a Harsh Environment with

High-Precision Output Conditioners and

Drivers

MAX9943/MAX9944

The MAX9943/MAX9944 are high-voltage ampliers (6V to 38V) that oer

precision (100µV

), low drift (0.4µV/°C), and low 550µA power consumption.

The devices are ideal for sensor signal conditioning, high-performance industrial

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

Benefits

• Easily drives 24V biased 4–20mA lines

throughout factory floors

◦ High supply-voltage operation and

high-output drive exceed current-

mode communication requirements
