The LT

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 150

µV, with an

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 0.1

µF output capacitor, which improves the

amplifier’s supply rejection and reduces output imped-

ance 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.
