DESCRIPTION
The INA148 is a precision low-power unity-gain difference amplifier with a high common-mode input voltage
range. It consists of a monolithic precision bipolar operational amplifier with a thin-film resistor network.
The on-chip resistors are laser trimmed for an accurate 1-V/V differential gain and high common-mode rejection.
Excellent temperature tracking of the resistor network maintains high gain accuracy and common- mode rejection
over temperature. The INA148 operates on single or dual supplies.
The INA148 is available in a small SO-8 surface-mount package, and it is specified for operation over the
temperature range of –40°C to 125°C.
