Most single, dual and quad op amps available have a standardized pin-out which permits one type to be substituted for another without wiring changes. A specific op amp may be chosen for its open loop gain, bandwidth, noise performance, input impedance, power consumption, or a compromise between any of these factors.
V+ and V− may also refer to the non-inverting (+) and inverting (−) voltage inputs of ICs like op amps. For power supplies, sometimes one of the supply rails is referred to as ground (abbreviated "GND") – positive and negative voltages are relative to the ground. In digital electronics, negative voltages are seldom present, and the ground ...

The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.
where Z dif is the op-amp's input impedance to differential signals, and A OL is the open-loop voltage gain of the op-amp (which varies with frequency), and B is the feedback factor (the fraction of the output signal that returns to the input). [3] [4] In the case of the ideal op-amp, with A OL infinite and Z dif infinite, the input impedance ...
Schematic symbol for an OTA has inverting (V in-) and noninverting (V in+) inputs, power supply lines (V + and V −), two biasing inputs (I abc and I bias), and a single output current I out. The LM13700 is an integrated circuit (IC) containing two current -controlled operational transconductance amplifiers (OTA), each having differential ...

Philips LM358D LM358 pinout LM358 die photo. The LM358 is a low-power dual operational amplifier integrated circuit, originally introduced by National Semiconductor. [1] It uses a single power supply from +3 to +30 volts for V CC (though some variants go higher, such as 36 volts for the LM358B). Input voltage can range from −0.3 volts to V CC.
