LT1494CMS8#PBF

产品概述

The LT1494CMS8#PBF is a lowest power 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 LT1494 easy to use in harsh environments. The low bias currents and offset current of the amplifier permit the use of mega ohm level source resistors without introducing significant errors.
