DESCRIPTION

The INA133 and INA2133 are high slew rate, unity­gain difference amplifiers 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
resistors maintains gain accuracy and common-mode
rejection over temperature. They operate over a wide
supply range, ±2.25V to ±18V (+4.5V to +36V single
supply), and input common-mode voltage range extends
beyond the positive and negative supply rails.

The differential amplifier is the foundation of many
commonly used circuits. The low cost INA133 and
INA2133 provide this precision circuit function without
using an expensive precision network.

The single version, INA133, package is the SO-8 surface
mount. The dual version, INA2133, package is the SO-14
surface mount. Both are specified for operation over the
extended industrial temperature range, –40°C to +85°C.
Operation is from –55°C to +125°C.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap­propriate 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.
