Product Summary

The INA111BU is a high speed, FET-input instrumentation amplifier offering excellent performance. The INA111BU 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. The applications of the INA111BU include medical instrumentation and data acquisition.
