# OP-Amp 564 Output Shutdown

I need to build a controllable output shutdown for the OPA 564 so I can force the amp to shut down. The solution in the datasheet uses an optocoupler but I rather use it with some pull-down resistor. My build uses dual-supply with +/- 6,2 V. In this link you have the datasheet of OP 564: http://www.ti.com/lit/ds/symlink/opa564.pdf

Could this be a solution?

• How about an analog Mux? MC4053? – analogsystemsrf Oct 29 '19 at 16:52
• The datasheet says above that picture, ... to shut down the OPA564 the voltage level of the logic signal must be level-shifted by some means. Do you believe a pull-down resistor will accomplish this? – KingDuken Oct 29 '19 at 16:53
• So how can I do this in the simplest way? – Goncalo Seruca Oct 29 '19 at 17:01
