LT1366/LT1367 LT1368/LT1369 Dual and Quad Precision Rail-to-Rail Input and Output Op Amps FeaTures DescripTion n
Input Common Mode Range Includes Both Rails
The LT®1366/LT1367/LT1368/LT1369 are dual and quad n
Output Swings Rail-to-Rail
bipolar op amps which combine rail-to-rail input and output n
Low Input Offset Voltage: 150µV
operation with precision specifications. These op amps n High Common Mode Rejection Ratio: 90dB maintain their characteristics over a supply range of 1.8V n High AVOL: >1V/µV Driving 10k Load to 36V. Operation is specified for 3V, 5V and ±15V supplies. n Low Input Bias Current: 10nA Input offset voltage is typically 150µV, with an open-loop n Wide Supply Range: 1.8V to ±15V gain AVOL of 1 million while driving a 10k load. Common n Low Supply Current: 375µA per Amplifier mode rejection is typically 90dB over the full rail-to-rail n High Output Drive: 30mA input range, and supply rejection is 110dB. n 400kHz Gain-Bandwidth Product The LT1366/LT1367 have conventional compensation n Slew Rate: 0.13V/µs which assures stability for capacitive loads of 1000pF or n Stable for Capacitive Loads Up to 1000pF less. The LT1368/LT1369 have compensation that requires a 0.1µF output capacitor, which improves the amplifier’s applicaTions supply rejection and reduces output impedance at high frequencies. The output capacitor’s filtering action reduces n Rail-to-Rail Buffer Amplifiers high frequency noise, which is beneficial when driving n Low Voltage Signal Processing A/D converters. n Supply Current Sensing at Either Rail n 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 L, LT, LTC, LTM, Over-The-Top, Linear Technology and the Linear logo are registered trademarks and C-Load is a trademark of Linear Technology Corporation.
