Feature Description (continued)

7.3.2 Bandwidth

Measurement bandwidth is affected by the value of the load resistor (RL). High gain produced by high values of

RL yield a narrower measurement bandwidth (see the Typical Characteristics graphs). For widest possible

bandwidth, keep the capacitive load on the output to a minimum. Reduction in bandwidth due to capacitive load

is shown in the Typical Characteristics graphs.

If bandwidth limiting (filtering) is desired, a capacitor can be added to the output (see Figure 12). This does not

cause instability.

7.4 Device Functional Modes

For proper operation the INA139 and INA169 devices must operate within their specified limits. Operating either

device outside of their specified power supply voltage range or their specified common-mode range results in

unexpected behavior and is not recommended. Additionally operating the output beyond their specified limits with

respect to power supply voltage and input common-mode voltage will also produce unexpected results. See the

Electrical Characteristics table for device specifications.
