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. 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/LT1367 and LT1368/LT1369 are dual and quad precision rail‑to‑rail input and output operational amplifiers. They feature low input offset voltage, high common‑mode rejection, and a wide supply range, making them suitable for low‑voltage signal processing and driving A/D converters.
The devices are offered in 8‑lead PDIP, 8‑lead SO, and 14‑lead SO packages with typical supply currents of 340‑520 pA per amplifier and can drive up to 30 mA into the load. Detailed electrical characteristics, absolute maximum ratings, and package dimensions are provided for design reference.
