LT1466L/LT1467L Micropower Dual/Quad Precision Rail-to-Rail Input and Output Op Amps Features s s s s s s s s DESCRIPTION The LT®1466L/LT1467L are dual/quad bipolar op amps that bine rail-to-rail input and output operation with precision specifications. Using a patented technique, both input stages of the LT1466L/LT1467L are trimmed: one at the negative supply and the other at the positive supply. The resulting mon mode rejection of 83d B minimum is much better than other rail-to-rail input op amps. A minimum open-loop gain of 400V/m V into a 10k load virtually eliminates all gain error. Operation is specified for 3V, 5V and ± 5V supplies. Unlike other rail-to-rail amplifiers, the input offset voltage of 390µV maximum is guaranteed across the entire rail-torail input range, not just at half supply. The graph below contrasts the VOS specifications of the LT1466L/LT1467L to a petitive part that is specified only at half supply. As can be seen, the LT1466L/LT1467L’s limits are much tighter for inputs near either supply. The LT1466L is available in 8-lead PDIP and SO-8 packages with the standard dual pinout. The LT1467L Features the standard quad pinout and is available in a 16-lead narrow SO package. , LTC and LT are registered trademarks of Linear Technology Corporation.
