Introduction

ADG608BN is an 8-channel low power, low voltage CMOS analog switch belonging to the family of Interface ICs, which also includes analog multiplexers/demultiplexers, multiplexers, and demultiplexers. The ADG608BN combines 8 analog switches in a single dual-in-line (DIP) package to reduce board space and cost. This analog switch has an improved signal-to-noise ratio (50dB signal-to-noise ratio) and low power consumption. In addition, it has very low threshold voltage (1.5V) and a low off leakage drive Current of ±50nA.

Application Field

The ADG608BN is typically used in analog signal routing. Its key features make it suitable for various applications, including audio systems, cellular phones, and other handheld products. It can be used as a versatile tool in low voltage circuit designs. It is also used for instrumentation, medical electronics and automotive products. The low voltage operation and low power consumption make it ideal for portable applications.

In addition, the ADG608BN can be used in a variety of digital systems such as microcontrollers and digital signal processors. In digital systems, it can be used to switch the output of a digital-to-analog converter. It can also be used as a voltage-controlled switch in power management applications. Furthermore, its low leakage current makes it ideal for digital input protection.

Working Principle

The ADG608BN is a very simple device that uses two control lines to switch between two analog signals. The two control lines, named A and B, are both low to select Channel A (A=0, B=0) and both high (A=1, B=1) to select Channel B. The ADG608BN can be used in 8:1 analog multiplexer/demultiplexer configuration. When A and B are both low, PSB and PSW pin inputs go high to select the individual channels.

When using the ADG608BN in 8:1 multiplexer/demultiplexer configuration, the 8 pins correspond to each channel. For example, when A=0 and B=1, pin 1, 2 and 3 can be used to switch the signals A, B and C respectively, while pin 4 and 5 can be used to switch between D, E and F respectively. The ADG608BN can be used as an 8:1 analog multiplexer/demultiplexer with no external components required.

The ADG608BN requires only very low power supply voltage (1.65V to 3.6V) to operate. It is TTL/CMOS logic compatible and is characterized up to a frequency of 60MHz. It is also temperature tested over the entire operating range (-40°C to +85°C). The ADG608BN is available in the SOT-23-6, MSOP-8 and SOIC-16 packages.

Conclusion

The ADG608BN is a low voltage, low power, 8-channel analog switch. It can be used as a versatile tool in low voltage circuit designs, such as audio and video systems, cellular phones, and other handheld products.
