DESCRIPTION
The LT ®1218/LT1219 are bipolar op amps which bine rail-to-rail input and output operation with precision specifications. Unlike other rail-to-rail amplifiers, the LT1218/ LT1219’s input offset voltage is a low 90µV 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 mon mode rejection of 97d B minimum is much better than other railto-rail input op amps. A minimum open-loop gain of 500V/m V into a 10k load virtually eliminates all gain error. The LT1218 has conventional pensation which assures stability for capacitive loads of 1000p F or less. The LT1219 has pensation 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...
