3V operation of linear technology op amps

George Erdi

Abstract

The performance of Linear Technology operational amplifiers that work well on a 3V supply is discussed.

Keywords

Operational amplifier

3V supply

The latest trend in digital electronics is the introduction of numerous ICs operating on regulated 3V or 3.3V power supplies. This is a logical development to increase circuit densities and to reduce power dissipation. In addition, many systems are directly powered by two AA cells or 3V lithium batteries. Clearly, analog ICs which work on 3V with good dynamic range to complement these digital circuits are, and will be, in great demand.

Many Linear Technology operational amplifiers work well on a 3V supply. The purpose ...
