The INA337 and INA338 (with shutdown) are high temperature, high-performance, low-cost, precision instrumentation amplifiers. They are true single-supply instrumentation amplifiers with very-low DC errors and input common-mode ranges that extends beyond the positive and approaches the negative 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 package. The INA338 (with shutdown) is offered in MSOP-10. Both are specified over the temperature range, -40°C to +125°C.
