说明

The INA326 and INA327 (with shutdown) are high-performance, low-cost, precision instrumentation amplifiers with rail-to-rail input and output. They are true single-supply instrumentation amplifiers with very low DC errors and input common-mode ranges that extends beyond the positive and negative rails. 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 INA326 (without shutdown) comes in the MSOP-8 package. The INA327 (with shutdown) is offered in an MSOP-10. Both are specified over the industrial temperature range, –40°C to +85°C, with operation from –40°C to +125°C.
