DescripTion
The LT
®
1366/LT1367/LT1368/LT1369 are dual and quad
bipolar op amps which combine rail-to-rail input and output
operation with precision specifications. These op amps
maintain their characteristics over a supply range of 1.8V
to 36V. Operation is specified for 3V, 5V and ±15V supplies.
Input offset voltage is typically 150µV, with an open-loop
gain A
VOL
of 1 million while driving a 10k load. Common
mode rejection is typically 90dB over the full rail-to-rail
input range, and supply rejection is 110dB.
The LT1366/LT1367 have conventional compensation
which assures stability for capacitive loads of 1000pF or
less. The LT1368/LT1369 have compensation that requires
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 reduces
high frequency noise, which is beneficial when driving
A/D converters.
The LT1366/LT1368 are available in plastic 8-pin PDIP
and 8-lead SO packages with the standard dual op amp
pinout. The LT1367/LT1369 feature the standard quad
pinout, which is available in a plastic 14-lead SO package.
These devices can be used as plug-in replacements for
many standard op amps to improve input/output range
and precision.
