The INA157 is a high slew rate, G = 1/2 or G = 2
difference amplifier consisting of a precision op amp
with a precision resistor network. The on-chip resis-
tors 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. The input common-
mode voltage range extends beyond the positive and
negative supply rails. It operates on? ±4V to? ±18V
supplies.
The difference amplifier is the foundation of many
commonly used circuits. The INA157 provides this
circuit function without using an expensive precision
resistor network. The INA157 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.
