Hi,all
Rail-to-Rail I/O operational amplifiers means (OTA) operational transconductance amplifier? The main parameter of OTA is transconductance and the input and ouput resistance is very high. And Rail-to-Rail I/O op-amps? Please can anyone help me?
A CA3080 eas the first transconductance amplifier IC. It is obsolete now. Then came the LM13600 then the LM13700.
They were used in the late 60's and early 70's for electric guitar effects. Nobody uses them today.

The very old CA3080 was a single transconductance amplifier. Today you can buy an LM13700 which is a dual transconductance amplifier that is a little different. Digikey has 243 in stock for $2.52US for the DIL package. They have 337 in a surface-mount package for $1.44US each.

The LM13700 was first produced about 39 years ago by National Semiconductor.
Today it is made by National Semi, New Japan Radio and many Chinese companies.
I don't know a newer one.
