DESCRIPTION

The INA110 is a versatile monolithic FET-input

instrumentation amplifier. Its current-feedback circuit

topology and laser trimmed input stage provide

excellent dynamic performance and accuracy. The

INA110 settles in 4

µs to 0.01%, making it ideal for

high speed or multiplexed-input data acquisition

systems.

Internal gain-set resistors are provided for gains of 1,

10, 100, 200, and 500V/V. Inputs are protected for

differential and common-mode voltages up to

±V

Its very high input impedance and low input bias

current make the INA110 ideal for applications

requiring input filters or input protection circuitry.

The INA110 is available in 16-pin plastic and ceramic

DIPs, and in the SOL-16 surface-mount package.

Military, industrial and commercial temperature range

grades are available.
