== Darlington pair buffers ==
Pins 7 and 8 are the inputs to a pair of Darlington pair buffers. These have nowhere as high an input impedance as a [[JFET]] input [[operational amplifier|op-amp]]. When an external op-amp is used instead, the unused buffer pins can safely be left floating.<ref>[https://e2e.ti.com/support/amplifiers/f/14/t/264305?Terminating-unused-darlington-buffer-in-LM13700- Terminating unused darlington buffer in LM13700?], TI E2E Community Amplifiers Forum</ref><ref>''Make: Analog Synthesizers'' by Ray Wilson, Maker Media, 2013, {{ISBN|1449345220}}</ref>
