MAX4680CWE+T

The MAX4680CWE+T is a family of low on-resistance, low voltage logic-controlled CMOS analog switches from Maxim Integrated. Features on the device range from low power consumption and wide operating temperature range, to low off-leakage current and low on-resistance. It boasts improved temperature coefficient performance over other CMOS switches, with its on-resistance shifting of a maximum of ?3?/°C over the entire operating temperature range. The device also supports up to 15V of signal handling capability while operating with a single supply voltage between 1.8V and 5.5V.

The MAX4680CWE+T family of devices includes two major types of components – analog switches, multiplexers, and demultiplexers. Analog switches, also known as transmission gate switches, are used to control the flow of electrical signals through a circuit, either completely blocking or allowing the flow of the signal. In terms configured to a multiplexer, the switches provide for a single input signal to be routed to different output channels based on the various select lines. The MAX4680 has sixteen single-pole, double-throw (SPDT) switches that can be configured as single switches, or as 8-channel multiplexers.

The working principle for the MAX4680CWE+T family is based on a CMOS transmission gate that acts like an electronic switch. When a logic control voltage is applied, the transmission gate is opened, allowing passage of the signal current. When no logic control voltage is applied, the transmission gate is closed, blocking the passage of the signal. The switch is optimized to ensure low on-resistance, high speed switching (tPD = 50ns max), and low power consumption.

The MAX4680CWE+T is a versatile device that finds a range of applications in signal switching, data transmission and communication, sensor signal conditioning, signal routing and signal multiplexing. The low voltage and low on- resistance features of the device make it optimal for applications requiring low power consumption. The device also finds applications in medical, industrial and consumer electronics systems.

In conclusion, the MAX4680CWE+T from Maxim Integrated is a generalpurpose, low-voltage, low-power device designed for signal switching, multiplexing, and demultiplexing applications. The device provides for low on-resistance, low power consumption, wide operating temperature range, and improved temperature coefficient performance.
