Hello everyone. i'm using a LM13700 double VCA in crossover amd i'm not using some pins: 2diode bias, 7/8 bufferin and out, 9/10 buffer in and out, 15diode bias
i would like to know what is supposed to do with all those pins. on the texas instrument forum i found out that i could leave 7,8,9,10 floating but no informations about the bias 2, 15
in case i don’t use half of the IC, what is the best practice in order to terminate it? i also wrote to T.I but no answer.
thanks for any help

With no bias there's only leakage currents flowing in the device, not an issue - leave all pins unconnected for the unused side. The scehmatic shows that everything derives current from the bias input, so it basically shuts down the circuit if no current flows.
the datasheet schematics shows that they are unconnected from the rest.
i just didn't want them to act strangely. i've read from some people around to ground the diode base and some other say to leave everything floating. i think the second (as you said) can be a good way
I normally ground the bias pin (1 or 16), and link the base-emitter pins of the darlington together (7+8 or 9+10). Let eveything else float.
