Notes:

1. The CS1610A/11A/12A/13A has an internal shunt regulator that limits the voltage on the VDD pin. V_Z, the shunt regulation

voltage, is defined in the VDD Supply Voltage section on page 4.

2. For test purposes, load capacitance C_Lis 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. Switching period (T1T2)  5s. Period T1 and T2 are defined in the Control Parameters section on page 12.

5. 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.

6. Specifications are guaranteed by design and are characterized and correlated using statistical process methods.
