DECOUPLING CAPACITOR
Particular care must be taken when connecting the device to power supply. A 47 µF tantalum capacitor must be
placed as close as possible of the MS5535C's VDD pin. This capacitor will stabilise the power supply during data
conversion and thus, provide the highest possible accuracy.
APPLICATION EXAMPLE: DIVING COMPUTER SYSTEM USING MS5535C
MS5535C is a circuit that can be used in connection with a microcontroller in diving computer applications. It is
designed for low-voltage systems with a supply voltage of 3 V, particularly in battery applications. The MS5535C
is optimised for low current consumption as the AD-converter clock (MCLK) can use the 32.768 kHz frequency of
a standard watch crystal, which is supplied in most portable watch systems.
