INA1 В® INA111 11 INA1 11 High Speed FET-Input
INSTRUMENTATION AMPLIFIER
FEATURES DESCRIPTION в—Џ FET INPUT: IB = 20pA max The INA111 is a high speed, FET-input instrumentation amplifier offering excellent performance. в—Џ LOW OFFSET VOLTAGE: 500ВµV max
в—Џ LOW OFFSET VOLTAGE DRIFT:
5ВµV/В°C max The INA111 uses a current-feedback topology providing extended bandwidth (2MHz at G = 10) and fast
settling time (4Вµs to 0.01% at G = 100). A single
external resistor sets any gain from 1 to over 1000. в—Џ HIGH SPEED: TS = 4Вµs (G = 100, 0.01%) в—Џ HIGH COMMON-MODE REJECTION:
106dB min 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. в—Џ 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. APPLICATIONS
