SBOS248 – JUNE 2002

Wide-Temperature, Precision

INSTRUMENTATION AMPLIFIER

DESCRIPTION

FEATURES

The INA337 and INA338 (with shutdown) are high tempera-

ture, high-performance, low-cost, precision instrumentation

amplifiers. They are true single-supply instrumentation ampli-

fiers with very-low DC errors and input common-mode ranges

that extends beyond the positive and approaches the nega-

tive rail. These features make them suitable for applications

ranging from general-purpose to high-accuracy.

● PRECISION

LOW OFFSET: 100µV (max)

LOW OFFSET DRIFT: 0.4µV/°C (max)

EXCELLENT LONG-TERM STABILITY

VERY-LOW 1/f NOISE

● SMALL SIZE

Excellent long-term stability and very low 1/f noise assure

low offset voltage and drift throughout the life of the product.

microPACKAGE: MSOP-8, MSOP-10

● LOW COST

The INA337 (without shutdown) comes in the MSOP-8 pack-

age. The INA338 (with shutdown) is offered in MSOP-10.

Both are specified over the temperature range, –40°C to

+125°C.

APPLICATIONS

● LOW-LEVEL TRANSDUCER AMPLIFIER FOR

BRIDGES, LOAD CELLS, THERMOCOUPLES
