CEN895 Application Field and Working Principle

The CEN895 is a bipolar junction transistor (BJT) array specifically designed for low noise digital and analog device applications. It is manufactured to high quality standards so as maximize its performance in low voltage and low power requirements. The CEN895 is an integrated digital and analog device. It comes in two varieties, NPN and PNP, both capable of supporting up to 5W of power. The CEN895 is ideal for transimpedance amplifiers, differential sensing amplifiers, low voltage precision voltage references, and low drift sensors, among many other applications.

The key feature of the CEN895 is its high performance and excellent noise immunity. The device is designed to operate in low voltage and low power environment, with minimum current consumption or circuit distortion. It produces a low noise output that is nearly free of noise or output switching, which is the most critical requirement for clean digital and analog device operation. At the same time, the CEN895 also delivers high input impedance with excellent linearity. This helps to reduce noise from external sources or other circuits in its vicinity.

The CEN895 features dual channels with separate complimentary outputs. This allows for differential input signals to be amplified and buffered for improved noise immunity. Furthermore, the power supply design is optimized for low voltage operation, and therefore offers superior transient immunity and low power consumption. In addition, the CEN895 comes with a host of integrated protection and diagnostic functions.

The CEN895 works on the principle of bipolar junction transistors (BJT). A BJT array consists of several transistors connected in a common base. A high voltage applied to the common base causes a current flow through the device, which then gets amplified by the base-emitter junction of the transistors. This amplified current is then sent to the collector, where it is outputted. The collector current is further amplified by the collector-emitter junction of the transistors. Once the amplified current is received by the collector, it is then sent to the base, thereby looping the circuit. This process is referred to as DC biasing.

The CEN895 is further optimized for excellent linearity. This is achieved through its constant current source, which allows for excellent input impedance and low noise in order to achieve the highest possible gain with very low harmonic distortion. Furthermore, the CEN895 is built with high-quality low-voltage polysilicon process technology, enabling it to operate with very low power consumption. This also ensures good temperature stability in multiple supply conditions.

The CEN895 is an ideal device for low noise digital and analog applications, meeting high performance and low voltage requirements with excellent noise immunity. Dimensions are 8 mm x 8 mm x 1.5 mm (1.2 cm³). Its integrated protection and diagnostic functions further add to its appeal in digital and analog device design. With high quality polysilicon process technology, low power consumption, good temperature stability and excellent linearity, the CEN895 is a practical solution for a wide variety of applications.
