The RN2962 (TE85L,F) is part of the family of Bipolar Transistor Arrays. It is a pre-biased array if transistors which form a set of two electronically identical NPN transistors connected in a Darlington configuration. This type of pre-biased array is designed with outputs which are held in a fully balanced state on power up, simulating a very low output impedance while assuring very low inversion current. To use the full power of the RN2962, its structure and characteristics must be understood.

The RN2962 is designed so that one of the transistors is factory-biased (via an adjustable emitter resistor), while the other is freshly biased once the input signal is applied. The constant current flowing through the Darlington transistor pair is usually divided equally between the two elements, thus providing excellent temperature drift characteristics.

The RN2962 can operate from a single-ended power supply, or from a split supply, and is capable of switching load currents up to 800mA. Its low power and excellent performance makes it well suited for applications such as audio, video and moderate-power motor-drive systems. Additionally, the pre-biasing, matched transistor pair, and high-impedance input features result in faster response times, improved video bandwidth and reduced component count.

The RN2962 can be used in a wide range of applications. Since it is a pre-biased array, it can easily be incorporated into systems without the need for external biasing components, thus providing excellent versatility and cost savings. Common applications include digital drive, audio and video circuits, motor control, and small power switching.

The RN2962 array is based on the principle of current-sharing. Current-sharing is made possible with the use of a Darlington configuration. Darlington transistors feature a common base-emitter junction (the PN junction found in bipolar transistors) connected in series with a second PN junction (the emitter-collector junction). This enables both elements to share a common current-sources, and it also reduces output impedance and reduces inversion current.

The pre-biased feature of the RN2962 ensures that the array is already biased when the input signal is applied. This eliminates the need for external biasing components, thus simplifying the design. Additionally, the RN2962 features matched transistors which further reduces transistors variations in output characteristics.

In addition to its versatility and low power requirements, the RN2962’s high-impedance input feature allows signals to be applied directly to the array without the need for external buffers or level shifters. This results in improved video bandwidth and reduced component count, thus resulting in cost savings. Furthermore, the RN2962 can operate from a single-ended or split power supply, thus allowing it to be used in applications which require either type of supply configuration.

Overall, the RN2962 is an excellent choice for applications which require a fast response time, improved video bandwidth, and low power requirements. Its pre-biased, matched transistors, and high-impedance input features make it an ideal choice for applications such as audio, video and moderate power motor-drive systems.
