LT1112S8

The LT1112S8 is one member of the LT1112 family which designed as the dual/quad low power precision, picoamp input op amps that achieve a new stand-ard in combining low cost and outstanding precision specifications. It can be used in (1)picoampere/microvolt instrumentation; (2)two and three op amp instrumentation amplifers; (3)thermocouple and bridge amplifiers; (4)low frequency active filters; (5)photo current amplifiers; (6)battery-powered systems and provides a full set of matching specifications, facilitating their use in such matching dependent applications as two and three op amp instrumentation amplifiers.

Features of the LT1112S8 are:(1)s8 package-standard pinout; (2)offset voltage-prime grade: 60mv max; (3)offset voltage-low cost grade (including surface mount dual/quad): 75mv max; (4)offset voltage drift: 0.5mv/°c max; (5)input bias current: 250pa max; (6)0.1Hz to 10hz noise: 0.3mvp-p, 2.2pap-p; (7)supply current per amplifier: 400ma max; (8)cmrr: 120db min; (9)voltage gain: 1 million min; (10)guaranteed specs with ±1.0 V supplies; (11)guaranteed matching specifications; (12)LT1112S8 in narrow surface mount package.

The absolute maximum ratings of the LT1112S8 can be summarized as:(1)supply voltage:±20V;(2)differential input current:±10mA;(3)input voltage (equal to supply voltage):±20V;(4)output short-circuit duration:indefinite;(5)storage temperature range:-65°C to 150°C;(6)lead temperature (soldering, 10 sec): 300°C;(7)operating temperature range:-40°C to 85°C.
