The '''LM13700''' inseries anconsists of two current controlled [[operational transconductance amplifier]], ors (OTA) foreach short.having Thedifferential lm13700inputs isand almosta identical to the LM13600, except that the darlingtonpush-pull output buffer is biased by the IABC input on the 13600. The LM13700 is like a standard [[op-amp]]: both have a pair of differential inputs and a single output, but an [[OTA]] is voltage in and current out rather than voltage in and voltage out; and OTAs are programmable via the IABC pin. Linearizing diodes at the input reduce distortion and allow increased input levels. The darlington outout buffers provided are specifically designed to complement the wide dynamic range of the OTA. This chip is very useful in audio electronics especially in [[analog synthesizer]] circuits like [[voltage controlled oscillator]]s, [[voltage controlled filter]]s, and [[voltage controlled amplifier]]s.
