DESCRIPTION

The INA152 is a small (MSOP-8), low-power, unitygain

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 commonmode

rejection over temperature. The input commonmode

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, –40°C to +85°C.
