INSTRUMENTATION AMPLIFIER

DESCRIPTION

FEATURES

The INA114 is a low cost, general purpose instrumen-

tation amplifier offering excellent accuracy. Its versa-

tile 3-op amp design and small size make it ideal for a

wide range of applications.

● LOW OFFSET VOLTAGE: 50µV max

● LOW DRIFT: 0.25µV/°C max

● LOW INPUT BIAS CURRENT: 2nA max

● HIGH COMMON-MODE REJECTION:

Asingleexternalresistorsetsanygainfrom1to10,000.

Internal input protection can withstand up to ±40V

without damage.

115dB min

● INPUT OVER-VOLTAGE PROTECTION:

±40V

TheINA114islasertrimmedforverylowoffsetvoltage

(50µV), drift (0.25µV/°C) and high common-mode

rejection (115dB at G = 1000). It operates with power

supplies as low as ±2.25V, allowing use in battery

operated and single 5V supply systems. Quiescent cur-

rent is 3mA maximum.

● WIDE SUPPLY RANGE: ±2.25 to ±18V

● LOW QUIESCENT CURRENT: 3mA max

● 8-PIN PLASTIC AND SOL-16

The INA114 is available in 8-pin plastic and SOL-16

surface-mount packages. Both are specified for the

–40°C to +85°C temperature range.

APPLICATIONS

● BRIDGE AMPLIFIER

● THERMOCOUPLE AMPLIFIER

● RTD SENSOR AMPLIFIER

● MEDICAL INSTRUMENTATION
