The darlington output buffers on the LM13700 are different from those on the LM13600 in that their bias currents (and hence their output DC levels) are independent of IABC pin. This may result in performance superior to that of the LM13600 in audio applications.
The LM13700's Darlington buffers differ from those on the LM13600 in that their bias currents (and consequently, their output DC levels) are independent of the IABC pin. This distinction may yield superior performance compared to the LM13600 in audio contexts.
