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.
