The INA152 is a small (MSOP-8), low-power, unity-gain difference amplifier consisting of a CMOS op amp and a precision resistor network. The on-chip resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistor maintains gain accuracy and common-mode rejection over temperature. The input common-mode voltage range extends to above the positive and negative rails and the output swings to within 50mV of either rail.
The difference amplifier is the foundation of many commonly used circuits. The INA152 provides precision circuit function without using an expensive precision network.
The INA152 is specified for operation over the extended industrial temperature range, \x9640°C to +85°C.
