The INA111 is a high speed, FET-input instrumenta-
tion amplifier offering excellent performance.
The INA111 uses a current-feedback topology provid-
ing extended bandwidth (2MHz at G = 10) and fast
settling time (4碌s 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鈥檚 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
鈥?0擄C to +85擄C temperature range.
