q PRECISION LOW OFFSET: 100µV (max) LOW OFFSET DRIFT: 0.4µV/°C (max) EXCELLENT LONG-TERM STABILITY VERY-LOW 1/f NOISE q SMALL SIZE microPACKAGE: MSOP-10 q LOW COSTDESCRIPTION
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, to +125°C.APPLICATIONS

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 10mA or less.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.BOLDFACE limits apply over the specified temperature range, to +125°C
