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.
