DESCRIPTION
The INA117 is a precision unity-gain difference
amplifier with very high common-mode input voltage
range. It is a single monolithic IC consisting of a
precision op amp and integrated thin-film resistor
network. It can accurately measure small differential
voltages in the presence of common-mode signals up
to
±
200V. The INA117 inputs are protected from
momentary common-mode or differential overloads
up to
±
500V.
In many applications, where galvanic isolation is not
essential, the INA117 can replace isolation amplifiers.
This can eliminate costly isolated input-side power
supplies and their associated ripple, noise and quies-
cent current. The INA117’s 0.001% nonlinearity and
200kHz bandwidth are superior to those of conven-
tional isolation amplifiers.
The INA117 is available in 8-pin plastic mini-DIP and
SO-8 surface-mount packages, specified for the –40
°
C
to +85
°
C temperature range. The metal TO-99 models
are available specified for the –40
°
C to +85
°
C and
–55
°
C to +125
°
C temperature range.
