CS3302

The VA- supply is connected to the CMOS sub-

strate and as such must remain the most negative

applied voltage to prevent potential latch-up condi-

tions. Care should be taken to ensure analog input

voltages do not drop more than -0.3 V below the

VA- supply. Care should also be taken to establish

the VA- supply before analog signals are applied to

the device. It is recommended to clamp the VA-

supply to system ground using a reverse biased

Schottky diode to prevent possible latch-up condi-

tions related to mismatched supply rail initializa-

tion.

2.3.2

Digital Power Supplies

The digital power supply across the VD and DGND

pins is flexible and can be set to interface with

3.3 V or 5 V logic. The digital power supply should

be bypassed to system ground using a 0.01

µF X7R

type capacitor.
