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 AVOL 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 imped ance at high frequencies. The output capacitor’s filtering action reduces high frequency noise, which is beneficial when driving A/D converters.
