Unlike other rail-to-rail amplifiers, the LT1218/ LT1219’s input offset voltage is a low 90 µV across the entire rail-to-rail input range, not just a portion of it. Using a patented technique, both input stages of the LT1218/ LT1219 are trimmed: one at the negative supply and the other at the positive supply. The resulting common mode rejection of 97dB minimum is much better than other rail- to-rail input op amps. A minimum open-loop gain of 500V/mV into a 10k load virtually eliminates all gain error. The LT1218 has conventional compensation which assures stability for capacitive loads of 1000pF or less. The LT1219 has compensation that requires the use of a 0.1µF output capacitor, which improves the amplifier’s supply rejection and reduces output impedance at high frequencies. The output capacitor’s filtering action also reduces high frequency noise, which is beneficial when driving A/D converters. High and low voltage versions of the devices are offered. Operation is specified for 3V, 5V and ±5V supplies for the LT1218L/LT1219L and 3V, 5V and ±15V for the LT1218/ LT1219.
