Hi,
I have a quastion about the "Shutdown pin" (pin 4).
1. what is the value of the inside voltage "Avdd" that the pullup resistor pulled ?
2. See below the schematic and the connection as I use in my design and let me know if this ok ?
see the Diode and the voltage that I use...
Thanks

Hello Arie,
The exact circuit at the SHDNb pin is shown below. The AVDD has typ 4.275V. The pull-up resistance will be 900kOhm till SHDNb pin voltage reaches 2.7V and after that it will be 200kOhm
Please check the diode connection at SHDN pin. Can you explain how you want to use the SHDN pin ?
Thanks
Amrit
