The CS1615/16 has an internal shunt regulator that limits the voltage on the VDD pin. Shunt regulation voltage V
Z
is defined in
the
section on
For test purposes, load capacitance C
L
is connected to pin GD and is equal to 0.25nF.
External circuitry should be designed to ensure that the ZCD current drawn from the internal clamp diode when it is forward biased
does not exceed specification.
Protection is implemented using pin FBSENSE. See the
on
Protection is implemented using pin FBAUX. See the
on
The conductance is specified in Siemens (S or 1/). Each LSB of the internal ADC corresponds to 250nS or one parallel 4M
resistor. Full scale corresponds to 256 parallel 4M resistors or 15.625k.
Specifications are guaranteed by design and are characterized and correlated using statistical process methods.
