  description

  LT^®The 1366/LT1367/LT1368/LT1369 are dual and quad bipolar operational amplifiers that 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. Its operating specifications are designed for 3V, 5V, and ±15V supplies. The input offset voltage is typically 150μV and provides an open-loop gain of 1,000,000 when driving a 10k load_VOL。 Common-mode rejection is typically 90dB over the entire rail-to-rail input range, while power supply rejection is 110dB.
  
  The LT1366/LT1367 use traditional compensation circuitry to ensure stability at capacitive loads ≤1000pF. The compensation circuit used in the LT1368/LT1369 requires a 0.1μF output capacitor, which improves the amplifier's power supply rejection and reduces the output impedance at high frequencies. The filtering operation of the output capacitor reduces high-frequency noise, which is advantageous when driving A/D converters.
  
  The LT1366/LT1368 are available in plastic 8-lead PDIP and 8-lead SO packages in standard dual op amp pin configurations. The LT1367/LT1369 are available in a 14-lead plastic SO package in a standard quad op amp pin configuration. These devices are used as drop-in replacements for many standard op amps to improve input/output range and accuracy
