FAQ: What are the values of source and sink currents at A and Y pin without external buffers?
Answer:
Table 1 of the specification table of ADG330x shows in the condition’s column that the current values are IOH/IOL = 20 µA. These current values are the ones that the ADG330x can source or sink to the next stage such, as microprocessor/microcontrollers or multiple peripheral devices.
If the load requires high-current drive capability, it is recommended to use external buffers such as ADA4891, AD8061, or AD8063 between the ADG330x outputs and the load.
