The LT1366/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 impedance 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.
