The ADG528ATQ is a high-performance, quad, SPST analog switch that can be used in a broad range of applications such as signal gating, bus switching, multiplexing, and sample-and-hold. It integrates two components into one package - a high-performance 4-channel analog switch plus a 4-to-1 multiplexer. It is capable of rapidly switching between its four logical channels and thus can provide significant performance enhancement in applications that require fast analog signal switching. The ADG528ATQ is available in an RoHS-compatible, 24-pin TSSOP package, making it ideal for use in portable equipment and other space-constrained environments.

The ADG528ATQ features an impressive array of features that make it well suited for a variety of applications. Its low on-resistance (RON) of 4 Ohms allows for minimal signal degradation and its low input leakage (Ioff) of 17pA ensures that there is no unwanted signal contamination. The wide -3V to +3V power supply rail allows it to operate in a variety of situations. The ADG528ATQ can also be operated as a four-channel multiplexer using its ABCD control inputs. When used as a multiplexer, the four signals can be selected simultaneously which increases its speed and flexibility. Furthermore, it features software-controlled shutdown and protected pin-to-pin short-circuits. Additionally, its ‘pin to VDD’ guarantee ensures that the pins are protected from transient voltage spikes.

The ADG528ATQ is ideal for a range of industrial and consumer applications needing high performance analog signal switching. It is suitable for use in radio and television production, broadcast switching, high-precision data acquisition, high-end audio systems, and power management. Additionally, its low on-resistance and high signal isolation make it suitable for signal routing applications such as audio and video routing, signal conditioning and signal multiplexing. It is also appropriate for applications such as multichannel signal selection, signal gating, and multiplexing. Furthermore, its low input leakage makes it suitable for computer and communication interfaces and for programming and reprogramming memory.

The ADG528ATQ operates on the principle of capacitive switching. In capacitive switching, the signal switches between two different capacitors, which creates a potential difference and signal discharge. This switching principle is fast and reliable, and it helps to maintain signal integrity during analog signal switching. Additionally, the ADG528ATQ features an on-chip auto-mux technology and on-chip termination resistors to ensure optimum signal quality.

The ADG528ATQ offers impressive performance in a variety of analog switch applications. Its fast switching speed, low on-resistance, and wide power supply rail make it ideal for a variety of applications requiring high-performance analog signal switching. Additionally, its two integrated components make it ideal for applications that require multiplexing or sample-and-hold. Due to its low on-resistance and high signal isolation, the ADG528ATQ is also a great choice for use in power management, communications, and memory applications. Finally, its low input leakage ensures that it can protect against transient voltage spikes and is suitable for a wide range of analog applications.
