Other Parts Discussed in Thread: LMP90079

The datasheet for the LM90079 Sensor AFE does not include any information on the current draw from the Digital Supply, only the Analog supply current draw.

Could you please supply this information.

Thanks

My apologies. The part number is LMP90079, a National Semiconductor Sensor AFE system.

Thanks
