DESCRIPTION
The LT®1466L/LT1467L are dual/quad bipolar op amps
that combine 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 common mode rejection of 83dB
minimum is much better than other rail-to-rail input op
amps. A minimum open-loop gain of 400V/mV into a 10k
load virtually eliminates all gain error. Operation is speci-
fied 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-to-
rail input range, not just at half supply. The graph below
contrasts the VOS specifications of the LT1466L/LT1467L
to a competitive 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 pack-
ages with the standard dual pinout. The LT1467L features
the standard quad pinout and is available in a 16-lead
narrow SO package.
