The LT1495IS8#PBF is a dual rail-to-rail input and output Operational Amplifier with precision specifications. The extremely low supply current is combined with excellent amplifier specifications, input offset voltage is 375μV maximum with a typical drift of only 0.4μV/°C, input offset current is 100pA maximum. A minimum open-loop gain (AVOL) of 100V/mV ensures that gain errors are small. The device characteristics change little over the supply range of 2.2 to ±15V. Supply rejection is 90dB and the common mode rejection ratio is 90dB. Operation is specified for 3, 5 and ±15V supplies. Reverse battery protection (-18V min) and inputs that operate above the positive supply make the LT1495 easy to use in harsh environments. The low bias currents and offset current of the amplifier permit the use of megohm level source resistors without introducing significant errors. Voltage noise at 4μVP-P is remarkably low considering the low supply current.
