Description
The INA117 is a precision unity-gain difference
amplifier with very high common-mode input voltage
range. The INA117 is a single monolithic IC consisting
of a precision op amp and integrated thin-film resistor
network. The device can accurately measure small
differential voltages in the presence of commonmode 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 design can eliminate costly isolated input-side
power supplies and the associated ripple, noise, and
quiescent current. The INA117 offers low nonlinearity
of 0.001% and a wide bandwidth of 200kHz (CSO:
SHE) or 500kHz (CSO: TID) (see specification note in
Section 5).
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.
