Evaluation Board Current Measurement
NOTES:
All IDC current numbers include bias circuitry current of 1.5mA to 2.0mA (dependent on mode).
TX Buffer On: Add 2mA to total current.
/2 Select On: Add 2mA to total current.
“X” denotes setting does not impact current.
*For Paging mode set IPSET=0. Total current reduced 2mA.
