Transistor array

ULN2803APG 8 channels Darlington sink driver.

Transistor arrays are used for general purpose applications, function generation and low-level, low-noise amplifiers. They include two or more transistors on a common substrate to ensure close parameter matching and thermal tracking, characteristics that are especially important for 'long tailed pair' differential amplifiers, current mirrors, log amplifiers.

Transistor arrays are composed of multiple transistors in one package and help to improve mounting density and reduce the board population costs associated with the use of discrete transistors.

Applications:

• Ham radio
• Analog synthesizer
• Vintage electronics
• Analog electronics in general
