INA111 - High Speed FET-Input INSTRUMENTATION AMPLIFIER

Download the INA111 datasheet PDF. This datasheet also covers the INA111_Burr variant, as both devices belong to the same high speed fet-input instrumentation amplifier family and are provided as variant models within a single manufacturer datasheet.

General 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 (4µs to 0.01% at G = 100).

A single external resistor sets any gain from 1 to over 1000.

Key Features

  • q FET INPUT: IB = 20pA max q LOW OFFSET.

® INA1 11 INA111 INA1 11 High Speed FET-Input INSTRUMENTATION AMPLIFIER FEATURES q FET INPUT: IB = 20pA max q LOW OFFSET VOLTAGE: 500µV max q LOW OFFSET VOLTAGE DRIFT: 5µV/°C max q HIGH COMMON-MODE REJECTION: 106dB min q 8-PIN PLASTIC DIP, SOL-16 SOIC q HIGH SPEED: TS = 4µs (G = 100, 0.01%) 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 (4µs 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.
