  description

  ®The LT 1366/LT1367/LT1368/LT1369 are dual and quad bipolar operational amplifiers that combine rail-to-rail input and output operational capabilities with precise specifications. These op amps maintain their characteristics over a 1.8V to 36V supply range. Operating specifications are developed for 3V, 5V, and ±15V power supplies. The input offset voltage is typically 150μV and provides an open-loop gain AVOL with a value of 1,000,000 when driving a 10k load. Common-mode rejection is typical for 90dB over the entire rail-to-rail input range, while supply rejection is 110dB. The LT1366/LT1367 feature traditional compensation function circuitry to ensure stability at capacitive loads ≤1000pF. The compensated circuitry used in the LT1368/LT1369 requires a 0.1μF output capacitor, which improves the amplifier's supply rejection and reduces output impedance at high frequencies. The filtering operation of the output capacitor reduces high-frequency noise, which is advantageous when driving an A/D converter. The LT1366/LT1368 are available in a plastic 8-pin PDIP package and an 8-pin SO package in a standard dual-channel op amp leader configuration. The LT1367/LT1369 are available in a 14-pin plastic SO package in a standard four-channel op amp pin configuration. These devices can be used as drop-in replacements for many standard op amps and are designed to improve input/output range and accuracy
