DESCRIPTION
The INA337 and INA338 (with shutdown) are high tempera-
ture, high-performance, low-cost, precision instrumentation
amplifiers. They are true single-supply instrumentation ampli-
fiers with very-low DC errors and input common-mode ranges
that extends beyond the positive and approaches the nega-
tive rail. These features make them suitable for applications
ranging from general-purpose to high-accuracy.
Excellent long-term stability and very low 1/f noise assure
low offset voltage and drift throughout the life of the product.
The INA337 (without shutdown) comes in the MSOP-8 pack-
age. The INA338 (with shutdown) is offered in MSOP-10.
Both are specified over the temperature range, –40
°
C to
+125
°
C.
