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.
