The MAX4544EUA+ is a low cost, single-supply, analog switch and multiplexer/demultiplexer device with a wide range of built-in features and performance. By utilizing a CMOS (Complementary Metal–Oxide Semiconductor) process, the MAX4544EUA+ offers low on-resistance, low power, and low charge injection characteristics and is suitable for a variety of application fields. This article will discuss the MAX4544EUA+ application fields and working principles.

Application Fields

The MAX4544EUA+ has multiple applications, making it suitable for many different systems. Its low on-resistance, low power and low charge injection make it well suited for applications such as sample-and-hold circuits, signal switching, amplifier gain switching, and analog multiplexing.

In sample-and-hold circuits, the MAX4544EUA+ can be used to selectively keep a signal “on” or “off” for a fixed amount of time. In signal switching applications, it can be used to switch a signal from one location to another. In amplifier gain switching, the MAX4544EUA+ can be used to switch between amplifier gain stages. Finally, in analog multiplexing, it can be used to route a signal from multiple sources to a single destination.

Working Principles

The MAX4544EUA+ features four switches and four multiplexers/demultiplexers. The switches have an “on” resistance of 2.5Ω at 10V and low charge injection. The multiplexers/demultiplexers have a maximum channel-to-channel isolation of -68dB at 1MHz. The control signals for the switches and multiplexers/demultiplexers are provided by the UNO-THRU pins, and the ALL-THRU pin allows for simultaneous control of all channels. This device operates from single supplies, such as 5V and 3V, up to 10V.

The MAX4544EUA+ is designed to be a cost-effective, low-power solution for a variety of applications. It has a low on-resistance, low charge injection, and high channel-to-channel isolation, making it suitable for sample-and-hold circuits, signal switching, amplifier gain switching, and analog multiplexing.
