SP Amp Difference Amplifier Single ±18V/36V 8-Pin SOIC Tube

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 surface-mount package and it is specified for the –40°C to +85°C extended industrial temperature range.
