Cirrus Logic CS1616A - Manual (Page 5)

CS1615A/16A
DS1033PP2 5
Notes: 1. The CS1615A/16A has an internal shunt regulator that limits the voltage on the VDD pin. Shunt regulation voltage V
Z
is defined
in the VDD Supply Voltage section on page 4.
2. For test purposes, load capacitance C
L
is connected to pin GD and is equal to 0.25nF.
3. 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.
4. Protection is implemented using pin FBSENSE. See the CS1615A/16A Block Diagram on page 2.
5. Protection is implemented using pin FBAUX. See the CS1615A/16A Block Diagram on page 2
6. 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.
7. Specifications are guaranteed by design and are characterized and correlated using statistical process methods.
