! Very low standby current
Ordering Information
Part No. (see paragraph 6)
EVB72015-433-FSK-A
Note 1: EVB default population is FSK, ASK modifications according to section 3.1 and 4.1.
Note 2: EVB72015 is applicable for devices TH72015, TH72011 and TH72012.
Application Examples
! General digital data transmission
! Tire Pressure Monitoring Systems (TPMS)
