Op Amps

bipolaropampswhichcombinerail-to-railinputandoutput

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

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.TheLT1368/LT1369havecompensationthatrequires

a 0.1µF output capacitor, which improves the amplifier’s

supply rejection and reduces output impedance at high

frequencies.Theoutputcapacitor’sfilteringactionreduces

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.
