It is particularly suited to applications in the field of medical, automotive, instrumentation and telecommunication. It has been used extensively in active filters, precision summing circuit, voltage dividers, and level-shifting applications where the low noise and low power consumption are advantageous.

Working Principle

LT1882HS#PBF is a dual op amp that uses the summing amplifier topology. It has two inputs which are the inverting and non-inverting inputs and is powered by a single positive power voltage. The two inputs are individually amplified and then summed together to form the output of the amplifier.

The inverting input is connected to ground and the non-inverting input is connected to the input signal voltage. The two inputs are then amplified with two gain stages and then summed together to create the output voltage. Owing to its high input impedance, the inverting input of the amplifier does not draw any current, but instead just amplifies the input signal.

Apart from the amplifying feature, the amplifier also has other important features like the common mode input range and the input offset voltage. The common mode input range is the maximum and minimum voltage levels that the amplifier can operate at without clipping or distortion. The input offset voltage is the voltage that the amplifier will produce when the two inputs are equal. This gives the amplifier its offset nulling feature.

Conclusion

LT1882HS#PBF is a high-performance low-power dual op amp that is suitable for use in instrumentation, low noise and gain stabilization applications. It has excellent gain accuracy, high common-mode input voltage range, excellent common-mode rejection ratio, low power consumption and high output voltage swing. It also has an excellent input offset voltage and drift for offset nulling. With its wide operating temperature range, LT1882HS#PBF makes an ideal choice for high-precision and reliable applications.
