3 Description

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 ±2.25 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.

The upgraded INA818 offers a lower input stage offset voltage (35 µV, maximum), lower input bias current (0.5 nA maximum) and lower noise (8 nV/√Hz) at the same quiescent current. See the Device Comparison Table for a selection of precision instrumentation amplifiers from Texas Instruments.
