The extremely low supply current is bined with excellent amplifier specifications: input offset voltage is 375µV maximum with a typical drift of only 0.4µV/°C, input offset current is 100p A maximum. A minimum open-loop gain (AVOL) of 100V/m V ensures that gain errors are small. The device characteristics change little over the supply range of 2.2V to ±15V. Supply rejection is 90d B and the mon mode rejection ratio is 90d B. Operation is specified for 3V, 5V and ±15V supplies. Reverse battery protection (- 18V␣ min) and inputs that operate above the positive supply make the LT1494/LT1495/LT1496 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. The LT1494 is available in the 8-Pin MSOP, PDIP and SO packages.The LT1495 is available in plastic 8-Pin PDIP and SO packages with the standard dual op amp pinout. The LT1496 is...
