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 150mV, with an open-loop gain AVOL of 1 million while driving a 10k load. Common mode rejection is typically 90dB over the full railto- 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 0.1mF 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.
