Question
Inquiry Description:For AD7660 recommended reference with 47uF capacitor. Can I use ADG441 asreference for AD7660? I cant wind information about maximum output capacitorfor ADR441.
Answer
The ADR441 can tolerate a 47uF capacitor load at the output. ADR441 can tolerate up to 1000uF at the output but with a large capacitive load therecan be current spikes during the start up with a ramp rate that is very fast.I would recommend you to test the start up current with a 47uF load to ensure that it does not cause any problems in your design.
