8.1 Application Information

8.1.1 Reference Pin

The output voltage of the INA600 is developed with respect to the voltage on the reference pin (REF). Often in

dual-supply operation, REF pin connects to the system ground. However, in single-supply operation, offsetting

the output signal to a precise mid-supply level is useful and required (for example, 2.5V in a 5.0V supply

environment). To accomplish this level shift, a voltage source must be connected to the REF pin to level-shift the

output so that the INA can drive a single-supply ADC. This is accomplished using an external reference buffer

configured in unity gain, voltage follower configuration as shown in Figure 8-1.
