In this book we have attempted to clarify some of the basic theory of audio amplifiers so that the reader will be better able to design his own or service commercial audio amplifiers.

This article introduces the internal functional circuits of CS42L55 and its basic operation.

This article will give the characteristics of the MAX2035 8-channel variable-gain amplifier.

This module will introduce the technology of voltage feedback operational amplifier and current feedback operational amplifier.

War! Maxim is waging war against National Semiconductor! Up to now the National Semiconductor troops (LM48555 and LM4802B) have controlled the territory (the market!), but now Maxim troops (MAX9730 and MAX9788) are ready to launch an attack. But which is the winner award?

The MCP6V01 Thermocouple Auto-Zeroed Reference Design demonstrates how to use a difference amplifier system to measure electromotive force (EMF) voltage at the cold junction of a thermocouple in order to accurately measure the temperature at the hot junction.

Similar circuit arrangements are used with both vacuum tube and transistor amplifiers. This similarity applies to the circuit arrangement only, however, and it is incorrect to consider the transistor as a direct substitute for the vacuum tube.

Fairchild’s High Performance (FHP) amplifiers offer optimal features and performance combinations for multi-market applications. This functionality allows designers the flexibility to choose high performance, low power or the perfect combination of both to optimize their systems: “Less Power, More Performance, More Possibilities.”

The FHP3194 is a 4:1 analog multiplexer designed for high-speed video applications. The output amplifier is a high-speed current feedback amplifier that offers stellar large signal performance of 500MHz -3dB bandwidth and 90MHz 0.1dB bandwidth.

The MAX2634 LNA with low-power shutdown mode is optimized for 308MHz, 315MHz, 418MHz, and 433MHz automotive RKE applications, which are required to operate over the -40°C to +125°C automotive temperature range.
