EL2480CSZ-T7 is a high-speed, low-offset, low-power voltage feedback operational amplifier (VFB op amp). It is a reliable and cost-effective solution for a variety of instrumentation and industrial control applications.

Application Field

EL2480CSZ-T7 is a high-speed operational amplifier that can be used for a wide range of applications, including industrial measurement, control, and monitoring. It is ideal for applications where fast settling and excellent linearity are required, such as control loops, amplifiers, filters, and data converters. Its low-noise and low-power characteristics make it particularly suitable for medical and instrumentation systems.

Working Principle

The EL2480CSZ-T7 can be used in voltage-feedback applications, where an input signal is input into the amplifier, which is then amplified and then sent to the output. The op amp\'s inputs are differential, balanced, and relatively insensitive to supply voltage and temperature variations.The input stage of the amplifier is an inverting and non-inverting input pair, allowing the amplifier to accept differential inputs and to reduce the effects of common-mode noise. The input stage is followed by an intermediate current-limiting stage to protect the output stage from short circuits or overpressure.The amplifier is then followed by a current mirror, consisting of two transistors which bias the output stage and amplify the differential signals. The output stage consists of a common-source, N-channel MOSFET which amplifies the small differential voltages and provides a high output, and a large resistor which sets the DC offset of the output.The output stage is followed by voltage feedback and then a power restoration network, which provides a low-impedance output drive capability. The EL2480CSZ-T7 includes an enable pin which can be used to enable or disable the amplifier, and a voltage reference pin which can be used to set the quiescent output voltage.

Conclusion

The EL2480CSZ-T7 is a versatile, high-speed, low-offset operational amplifier that can handle a wide range of industrial measurement and control applications. Its low-noise and low-power characteristics make it well suited for medical and instrumentation systems. The amplifier has a differential input stage, a current mirror, and a common-source MOSFET output stage, and it includes a voltage reference pin and an enable pin. Its fast settling and excellent linearity make it ideal for applications where excellent performance is required.
