    Hello Ian,

    Thanks for reaching out on the forum. If you are looking for an adjustable gain part like the INA138, we do not have another option with lower quiescent current. The lowest quiescent current of any of our actively operating parts would be 13uA typical. That is for our INA216. However, if your customer does not need to constantly measure and is only making periodic measurements, they may consider disabling one of our parts when not in use. One particular device that can be disabled is the INA190. This device when disabled consumes 10nA typical.
