The LT1366 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 have conventional compensation which assures stability for capacitive loads of 1000pF or less. The output capacitor’s filtering action reduces high frequency noise, which is beneficial when driving A/D converters.

The LT1366 are available in plastic 8-pin PDIP and 8-lead SO packages with the standard dual op amp pinout. These devices can be used as plug-in replacements for many standard op amps to improve input/output range and precision.
