The INA118 is a low power, general purpose instru-mentation amplifier offering excellent accuracy. Itsversatile 3-op amp design and small size make it idealfor a wide range of applications. Current-feedbackinput circuitry provides wide bandwidth even at highgain (70kHz at G = 100).A single external resistor sets any gain from 1 to 10,000.Internal input protection can withstand up to ±40Vwithout damage.The INA118 is laser trimmed for very low offset voltage(50µV), drift (0.5µV/°C) and high common-mode re-jection (110dB at G = 1000). It operates with powersupplies as low as ±1.35V, and quiescent current is only350µA—ideal for battery operated systems.The INA118 is available in 8-pin plastic DIP,and SO-8 surface-mount packages, specified forthe –40°C to +85°C temperature range.
