Texas Instruments INA118U
The INA118 is a low-power, general-purpose instrumentation amplifier offering excellent accuracy. The devices versatile, 3-op amp design and small size make it ideal 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 the device ideal for battery-operated systems.
The INA118 is available in 8-pin plastic DIP and SO-8 surface-mount packages, specified for the 40°C to +85°C temperature range.
