the manual tip the output pin Vcmof the LTC2217 chip is 1.575V,up or down 0. 1V，but measure the output voltage of the chip's correspond pin(pin 3) with multimeter,the voltage is only 1.27V.This phenomenon appears in all LTC2217 chips.
And I check the serials of LTC22xx ,only LTC2217 chip's Vcm is 1.575V,others are 1.25V(up or down 0. 1V).
I want to kown this phenomenon is the problem of the chip? Or the problem of the manual?
Thanks to the relevant engineers can give me your essential reply！
