LM13700: Difference between revisions

The '''LM13700''' in an [[operational transconductance amplifier]], or OTA for short. The lm13700 is almost identical to the LM13600 except that the darlington 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. 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. The OTA chip utilizes a differential input stage and [[current mirror]]s to to achieve its unique circuit characteristics.
