Hi FlightRisk,

Thank you for posting this inquiry.

You may consider AD8218 as a possible bidirectional current sense alternative for LT6108. It has a high common-mode voltage range of 4V to 80V. The output transfer function is OUT (V) = (20 × VIN) + VREF…

Actually the LT6108 could also be a good one to use for limiting the input current.

Hi Alberto, 

The DC2770A-A-KIT may not be good for 10mA wireless receiver, without any changes. The design should be re-configured for such low output power. 

The DC2770A-A-KIT is configured to run fixed duty cycle for the Auto-Resonant driver. For 10mA…
