DESCRIPTION

The INA111 is a high speed, FET-input instrumentation

amplifier offering excellent performance.

The INA111 uses a current-feedback topology providing

extended bandwidth (2MHz at G = 10) and fast

settling time (4ms to 0.01% at G = 100). A single

external resistor sets any gain from 1 to over 1000.

Offset voltage and drift are laser trimmed for excellent

DC accuracy. The INA111’s FET inputs reduce input

bias current to under 20pA, simplifying input filtering

and limiting circuitry.

The INA111 is available in 8-pin plastic DIP, and

SOL-16 surface-mount packages, specified for the

–40°C to +85°C temperature range.
