Note 1)

The maximum voltage is defined by forcing 10mA on COIL1 - COIL2

Note 2)

The tolerance of the resonant capacitor is ± 15% over the whole production.

Optional reduced tolerance on request

On a wafer basis, the tolerance is ± 2%

Timing Characteristics

VDD = 1.5V, VSS = 0V, fcoil = 134kHz square wave, Ta = 25°C

VC1 = 1.0V with positive peak at VDD and negative peak at VDD -1V unless otherwise specified

Timings are derived from the field frequency and are specified as a number of RF periods.
