8.3.8 Dynamic Performance

Figure 19 illustrates that, despite having low quiescent current of only 200 µA, the INA827 achieves much wider bandwidth than other instrumentation amplifiers (INAs) in its class. This achievement is a result of using TI’s proprietary high-speed precision bipolar process technology. The current-feedback topology provides the INA827 with wide bandwidth even at high gains. Settling time also remains excellent at high gain because of a 1.5-V/µs high slew rate.
