This setting is valid for other transconductance operational amplifiers. The circuit is from Motorola's 1990 Linear Databook. The power supply must be symmetrical.
This circuit was found in European documentation from the 1980s. The unijunction may be 2N2646 and the...
This amplifier was found in Burr-Brown documentation from the 90's. The gain can be programmed by resistor...
In the circuit shown in the figure, when the input voltage rises to 27 V, the TL431 triggers the...
