в—Џ SO-8 PACKAGE 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
+85В°C extended industrial temperature range. APPLICATIONS …
