DESCRIPTION
The INA110 is a versatile monolithic FET-input
instrumentation amplifier. Its current-feedback circuit topol-
ogy and laser trimmed input stage provide
excellent dynamic performance and accuracy. The INA110
settles in 4µs 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_CC. 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, indus-
trial and commercial temperature range grades are available.
