High-Voltage, Precision, Low-Power Op Amps  
3/MAX94  
General Description  
The MAX9943/MAX9944 is a family of high-voltage  
amplifiers that offers precision, low drift, and low-power  
consumption.  
Features  
o Wide 6V to 38V Supply Range  
o Low 100µV (max) Input Offset Voltage  
o Low 0.4µV/°C Offset Drift  
The MAX9943 (single) and MAX9944 (dual) op amps  
offer 2.4MHz of gain-bandwidth product with only  
550μA of supply current per amplifier.  
o Unity Gain Stable with 1nF Load Capacitance  
o 2.4MHz Gain-Bandwidth Product  
o 550µA Supply Current  
The MAX9943/MAX9944 family has a wide power sup-  
ply range operating from 3ꢀ to ꢁ9ꢀ dual supplies or  
a 6ꢀ to 38ꢀ single supply.  
o 20mA Output Current  
o Rail-to-Rail Output  
The MAX9943/MAX9944 is ideal for sensor signal condi-  
tioning, high-performance industrial instrumentation and  
loop-powered systems (e.g., 4mA–20mA transmitters).  
o Package Options  
3mm x 5mm, 8-Pin µMAX or 3mm x 3mm, 6-Pin  
TDFN Packages (Single)  
5mm x 6mm, 8-Pin SO or 3mm x 3mm, 8-Pin  
TDFN Packages (Dual)  
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 +ꢁ25°C automotive tempera-  
ture range.
