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 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

will operate on single or dual supplies.

The INA148 is available in a small SO-8 surfacemount

package and it is specified for the –40°C to

+85°C extended industrial temperature range.
