INA326 General 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.

INA326 Maximum Ratings

Supply Voltage .................................................................................. +5.5V
Signal Input Terminals: Voltage(2) ............................ 0.5V to (V+) + 0.5V
Current(2) .................................................. ±10mA
Output Short-Circuit .................................................................. Continuous
Operating Temperature Range ......................................... 40 to +125
Storage Temperature Range ............................................ 65 to +150
Junction Temperature ...................................................................... +150
Lead Temperature (soldering, 10s) ................................................. +300

NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less.
