The LT ®1218/LT1219 are bipolar op amps which combine rail-to-rail input and output operation with precision specifications. Unlike other rail-to-rail amplifiers, 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. A minimum open-loop gain of 500V/mV into a 10k load virtually eliminates all gain error. 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. s s s s s Rail-to-Rail Input and Output 90µV VOS(MAX) for VCM = V – to V + High Common Mod...
