DESCRIPTION
The INA154 is a high slew rate, unity-gain difference
amplifier consisting of a precision op amp with a
precision resistor network. The on-chip resistors are
laser trimmed for accurate gain and high common-
mode rejection. Excellent TCR tracking of the resis-
tors maintains gain accuracy and common-mode re-
jection over temperature. The input common-mode
voltage range extends beyond the positive and nega-
tive supply rails. It operates on ±4V to ±18V supplies.
The difference amplifier is the foundation of many
commonly used circuits. The INA154 provides this
circuit function without using an expensive precision
resistor network. The INA154 is available in a SO-8
surface-mount package and is specified for operation
over the extended industrial temperature range, –40°C
to +85°C.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
