Introduction

The LM2902KVQDRG4Q1 is an Analog Devices Inc. amplifier designed for low-voltage operation. It is part of the company’s industrial linear-amplifiers range and is classified as an Instrumentation, OP Amp, Buffer Amp. It is widely used in instrumentation, audio, and control circuits. This article will discuss the LM2902KVQDRG4Q1’s application field and working principle.

LM2902KVQDRG4Q1 Application Field

The LM2902KVQDRG4Q1 is a dual-channel, low-voltage amplifier that features a common-mode voltage range of 5.4V to 36V and bipolar input/output voltage range of -40V to +40V. It is available in a PDIP, SOIC, or DIP package, with a power supply voltage range of 4.5V to 36V.The LM2902KVQDRG4Q1 amplifier is mainly used in applications such as automotive, industrial, instrumentation, medical, and audio. It is also suitable for a range of other applications, including remote control systems, no-voltage switching circuits, and LED displays.

LM2902KVQDRG4Q1 Working Principle

The LM2902KVQDRG4Q1 is a dual-channel, low-voltage amplifier designed to provide high performance. It has two independent gain stages (polarity-reversing, positive gain, and negative gain stages); each channel has a maximum gain of 200. The LM2902KVQDRG4Q1 also features a slew rate of 0.5V/µs and an output current capability of 5 mA.The LM2902KVQDRG4Q1 amplifier is designed to use minimal power, with a quiescent current of just 3mA. This makes it ideal for use in battery-operated and low-power applications.The LM2902KVQDRG4Q1 amplifier is powered by a single supply, which is connected to the power supply pins (+V and -V). The input signals are connected to the input pins (IN+ and IN-). The amplifier amplifies the input signals and outputs the amplified signals to the output pins (OUT+ and OUT-).The LM2902KVQDRG4Q1 also has an enable pin (EN) that can be used to enable and disable the amplifier. When the enable pin is high, the amplifier is enabled; when it is low, the amplifier is disabled.

Conclusion

The LM2902KVQDRG4Q1 is a dual-channel, low-voltage amplifier designed for use in a variety of industrial, automotive, and instrumentation applications. It is powered by a single supply and features an enable pin, a maximum gain of 200, and a slew rate of 0.5V/µs. The quiescent current of the LM2902KVQDRG4Q1 is 3mA, making it ideal for low-power and battery-operated applications.
