The INA118 is a low power, general purpose instrumentation
amplifier offering excellent accuracy. Its
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 (70kHz at G = 100).
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to ±40V
without damage.
The INA118 is laser trimmed for very low offset voltage
(50mV), drift (0.5mV/°C) and high common-mode rejection
(110dB at G = 1000). It operates with power
supplies as low as ±1.35V, and quiescent current is only
350mA—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.?
