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.
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
