Notes:
1. Most of pins are protected by the ESD protection circuits. However pins, V+, V-, AGND, DGND and
VR1 are not protected enough because the parasitic effect must be decrease. Therefore enough external
protection is needed for assembling, carrying and keeping. In addition, components connecting to these
unprotected pins have to be soldered on board before the IC is soldered.
2. Cp is the compensation capacitor for measuring capacitance. Its value depends on the parasitic
capacitor on the PCB board.
3. Light shielding for the diodes and Zener diodes.
