INA118U2K5

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

amplifiers from Texas Instruments.
