DESCRIPTION The INA114 is a low cost, 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.A single external resistor sets any gain from 1 to 10,000.Internal input protection can withstand up to =B140V without damage.The INA114 is laser trimmed for very low offset voltage 50=ECV), drift (0.25=ECV/=B0C) and high common-mode ejection (115dB at G =3D 1000). It operates with power upplies as low as =B12.25V, allowing use in battery perated and single 5V supply systems. Quiescent current is 3mA maximum.The INA114 is available in 8-pin plastic and SOL-16 urface-mount packages. Both are specified for the -
40=B0C to +85=B0C temperature range.
