INA118 

Precision, Low Power INSTRUMENTATION AMPLIFIER. 

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 (50µV), drift (0.5µV/°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 350µA—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.


FEATURES of INA118

  • LOW OFFSET VOLTAGE: 50µV max
  • LOW DRIFT: 0.5µV/°C max
  • LOW INPUT BIAS CURRENT: 5nA max
  • HIGH CMR: 110dB min
  • INPUTS PROTECTED TO ±40V
  • WIDE SUPPLY RANGE: ±1.35 to ±18V
  • LOW QUIESCENT CURRENT: 350µA
  • 8-PIN PLASTIC DIP

APPLICATIONS of INA118 Instrumentation Amplifier

  • BRIDGE AMPLIFIER
  • THERMOCOUPLE AMPLIFIER
  • RTD SENSOR AMPLIFIER
  • MEDICAL INSTRUMENTATION
  • DATA ACQUISITION
