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 sup-
ply 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
8-pin SO or an 8-pin TDFN package. These devices are
specified over the -40°C to +125°C automotive tempera-
ture range.
