INA118 Precision Low Power Instrumentation Amplifier – DIP-8 Package
The INA118 is a low-power, general-purpose instrumentation amplifier offering excellent accuracy. The versatile, three op amp design and small size make this device an excellent choice for a wide range of applications. Current-feedback input circuitry provides wide bandwidth, even at high gain (70 kHz at G = 100). A single external resistor sets any gain from 1 to 10000. Internal input protection can withstand up to ±40 V without damage. The INA118 is laser-trimmed for low offset voltage (50 µV), drift (0.5 µV/°C), and high common-mode rejection (110 dB at G = 1000). The INA118 operates with power supplies as low as ±1.35 V, and quiescent current is only 350 µA, making this device an excellent choice for battery-operated systems. The INA118 is available in 8-pin plastic DIP and SO-8 surface-mount packages, and specified for the –40°C to +85°C temperature range. This product is known as INA118UB/2K5, INA118UB, INA118U/2K5, INA118U,INA118PB, INA118UG4, INA118P, INA118UB/2K5G4, INA118U/2K5G4, INA118UBG4.
