MTI0117仪表放大器可替代INA133
Description
The MTI0117 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 MTI0117 inputs are protected from
momentary common-mode or differential
overloads up to ±500V. In many applications,
where galvanic isolation is not essential, the
MTI0117 can replace isolation amplifiers. This
can eliminate costly isolated input-side power
supplies and their associated ripple, noise and
quiescent current. The MTI0117’s 0.001%
nonlinearity and 200kHz bandwidth are superior
to those of conventional isolation amplifiers
