1 Operational Transconductance Amplifier (OTA)

LM13700 is a dual Operational Transconductance Amplifier. The IC consists of two current-controlled transconductance amplifiers, each with differential inputs and a push-pull output. LM13700 is available in a 16-pin hermetically sealed dual inline IC package. The IC also offers a wide variety of features such as high impedance buffer input and a good SNR (signal to noise ratio).

Operational Transconductance Amplifier (OTA)

Operational transconductance amplifier is basically an amplifier, that produces an output current, when a differential input voltage is applied. It is also known as a voltage to current converter. OTA amplifiers are similar to general amplifier, with the only difference being that an OTA has a high impedance differential input stage, that may be used with negative feedback.
