ADG453BRZ-REEL7 is a monolithic CMOS quad SP4T analog switch characteristics of low on-resistance flatness, low-power and low-voltage operation. It has a breakdown voltage of ± 15V and a low-on-resistance of 45 Ohms. It is particularly suitable as a single analog switch or multiplexer/demultiplexer in a variety of applications such as audio, video, telecommunications, and instrumentation. This device is provided in a SOIC (Small Outline Integrated Circuit) package and is suitable for surface mount applications.

Application Fields

The ADG453BRZ-REEL7 is primarily employed when a low-on resistance analog switch is required in a high-performance single-pole 4-way switch or multiplexer/demultiplexer. It is an excellent choice for applications where switching from a high impedance to a low impedance or from a low impedance to a high impedance is desired. The device is also suitable for audio, video, telecommunications, and instrumentation. It is particularly suitable for audio applications such as headphone volume control, preamplifier selection, line selector switches, and switching between telephony and music switching. The device is also ideal for video applications, providing excellent isolation between channels and fast turn-on times. It can also be used for switching video signals between monitors, routers and other video devices, and for multiplexing and demultiplexing video. Additionally, the device is suitable for instrumentation applications such as frequency selection, network selection, and impulse selector switches.

Working Principle

The ADG453BRZ-REEL7 is a monolithic CMOS quad SP4T analog switch which operates from a single supply voltage of ± 15 V and has a low on resistance of 45 Ohms. It is provided in an SOIC package, allowing for easy surface mount applications. The device uses CMOS logic to control its analog switches, meaning that the switches are designed with built-in complementary and switchable transistors on the same chip. This allows for a fast turn-on and low-on resistance, without sacrificing switching speed. The device’s low-on-resistance is achieved by using symmetrical metal-oxide-semiconductor (MOS) differential pairs and by providing excellent isolation between channels. Additionally, the switch has a breakdown voltage of ±15 V, allowing for safe operation and protection against voltage spikes.

In operation, the device’s low-on-resistance allows it to switch with minimal power consumption, while its high speed allows for faster switching times. The device can be operated by applying either a logic level source or a direct current control signal to its control inputs. The device’s outputs can be enabled or disabled using either a simple logic level or a current source. Each switch has integrated power clamps to protect against voltage transients.

The ADG453BRZ-REEL7 is an excellent choice for applications where a low on-resistance and fast switching speed are required. It is suitable for various audio, video, telecommunications and instrumentation applications, as well as for multiplexing and demultiplexing. The device’s excellent isolation and breakdown voltage allow for safe operation, while its CMOS logic controls provide fast turn-on and low-on resistance.
