DESCRIPTION
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 preci-
sion circuit function without using an expensive pre-
cision network.
The INA152 is specified for operation over the ex-
tended industrial temperature range, –40°C to +85°C.
