The INA148 is a precision, low-power, unity-gain difference amplifier with a high common-mode input voltage range. The device consists of a monolithic precision bipolar op amp with a thin-film resistor network.

The on-chip resistors are laser trimmed for an accurate 1V/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 SOIC-8 surface-mount package and is specified for the –40°C to +85°C industrial temperature range.
