PUMD3,125

The PNUpdiMUX 3,125 (hereafter referred to as “PUMD-3,125”) is a pre-biased array of transistors designed for low-power, low-voltage, low-frequency audio applications. The PUMD-3,125 borrows from both bipolar junction transistor (BJT) and metal oxide field effect transistor (MOSFET) technologies to provide extremely low distortion, high linearity, and enhanced frequency response. It has been used in a wide variety of applications, including low-frequency audio amplifiers and audio mixers.

The PUMD-3,125 consists of three transistors, arranged in an array configuration. Each of the three transistors has its own dedicated base and collector electrodes, allowing for greater flexibility in the design of audio circuits. The transistors are also arranged in a way that allows for low voltage and low power operation, and their pre-biased state helps to reduce distortion and improve linearity in low-frequency applications.

The PUMD-3,125 takes advantage of MOSFET technology to help reduce the physical size of the device, as well as the power consumption. By eliminating the need for a discrete heat sink and larger power supply, designers can achieve efficiency gains while still maintaining low distortion and linearity. Additionally, the array arrangement of the transistors helps to reduce the amount of noise generated by the device by allowing greater control over the output transistor current.

In addition to its smaller size and lower power consumption, the PUMD-3,125 also offers exceptional audio performance. Its low-voltage operation, high linearity, and enhanced frequency response help to reduce distortion and improve clarity in audio circuits. Furthermore, the pre-biased state of the transistors helps to reduce phase distortion, which is a common issue in low-frequency audio circuits.

The PUMD-3,125 is well-suited for audio applications where space is limited, such as in headphones, portable music players, and speakers. Its low-power operation and pre-biased state make it an ideal choice for applications where low distortion is desired. Additionally, its enhanced frequency response and high linearity make it an ideal choice for audio mixers and amplifiers that need to produce clear, accurate sound.

The PUMD-3,125 is a versatile device, capable of meeting the needs of many different audio applications. Its small size, low power consumption, and pre-biased state make it ideal for many low-voltage, low-power audio applications, while its enhanced frequency response and high linearity make it ideal for high-power audio applications, such as those found in mixers and amplifiers. The PUMD-3,125 is an excellent choice for any application that requires low-distortion, accurate sound.
