FEATURES  
DESCRIPTION  
FET INPUT: IB = 20pA max  
The INA111 is a high speed, FET-input instrumenta-  
tion amplifier offering excellent performance.  
HIGH SPEED: TS = 4µs (G = 100, 0.01%)  
LOW OFFSET VOLTAGE: 500µV max  
The INA111 uses a current-feedback topology provid-  
ing extended bandwidth (2MHz at G = 10) and fast  
settling time (4µs to 0.01% at G = 100). A single  
external resistor sets any gain from 1 to over 1000.  
LOW OFFSET VOLTAGE DRIFT:  
5µV/°C max  
HIGH COMMON-MODE REJECTION:  
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.  
106dB min  
8-PIN PLASTIC DIP, SOL-16 SOIC  
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.
