LM2902KAVQPWRG4 application field and working principle

The LM2902KAVQPWRG4 is a precision quad op-amp belonging to the Linear – Amplifiers – Instrumentation, OP Amps, Buffer Amps category. It is offered in a 14-Pin leaded package, and has been designed to provide superior performance and ease of use in selective applications.

The LM2902KAVQPWRG4 has a gain bandwidth product of 5.5 MHz, with a low noise figure of 7.4 µV/√Hz and a high input impedance of 2.2 MΩ. With its low input bias current of 5 nA and low input voltage offset cur- rent of 0.5 nA, the LM2902KAVQPWRG4 is ideal for high input impedance needs. The LM2902KAVQPWRG4 also features a wide supply voltage range from 5 V to 24 V, which allows for multiple supply voltage applications, along with rail-to-rail outputs and low power consumption, enabling a wide variety of appli- cations.

Application Field

The LM2902KAVQPWRG4 can be used in a wide range of applications, such as signal conditioning, analog buffers, frequency conversion, and low-level signal processing. It is well suited for use in instrumentation and test and measurement applications, where accurate measurement of small signals is required. Additionally, it can be used in precision low noise amplifiers, oscillators, analog to digital (A/D) converters, and audio preamplifiers, to name a few.

Working Principle

The LM2902KAVQPWRG4 has four op-amp channels, each with its own input, output, and supply pins. Each channel contains a differential pair of transistors and a voltage-divider biasing network. The differential pair operates as a voltage comparator, comparing the voltages between its positive and negative inputs. When a difference in volts is detected, the transistor pair will respond and a current will be generated across the two outputs. This current can then be used to generate a voltage or drive a transistor or logic gate in a circuit.

Each op-amp has its own bias network which helps to minimize offset voltage and minimize voltage drift. Additionally, the LM2902KAVQPWRG4 has an integrated transformer to minimize distortion, noise, and harmonic content in the signal path. It also has an adjustable input stage for increased input impedance and a balanced output stage for improved signal-to-noise ratio.

The LM2902KAVQPWRG4 is ideal for use in applications that require low noise and high accuracy. It provides a low offset voltage and wide operating temperature range, while its low power consumption, combined with its wide supply voltage range, makes it suitable for use in portable and battery-powered devices.
