9 Power Supply Recommendations

The LM94022/-Q1 low supply current and supply range of 1.5 V to 5.5 V allow the device to easily be powered from many sources.

Power supply bypassing is optional and is mainly dependent on the noise on the power supply. In noisy systems it may be necessary to add bypass capacitors to the lower the noise that couples to the output of the LM94022/-Q1.
