DESCRIPTION

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.
