INA118U Instrumentation amplifier, 1-fold, 0.9 V/µs, 800 kHz, SO-8

Precision, Low Power Instrumentation Amplifier

Description The INA118 is a low-power, general-purpose instrumentation amplifier offering excellentaccuracy. The versatile, three op amp design and small size make this device an excellent choicefor a wide range of applications. Current-feedback input circuitry provides wide bandwidth, even athigh gain (70 kHz at G = 100).A single external resistor sets any gain from 1 to 10000. Internal input protection canwithstand up to ±40 V without damage. The INA118 is laser-trimmed for low offset voltage (50 µV), drift (0.5 µV/°C), and highcommon-mode rejection (110 dB at G = 1000). The INA118 operates with power supplies as low as ±1.35V, and quiescent current is only 350 µA, making this device an excellent choice forbattery-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.
