The MAX4661EWE+ is an advanced, 4-channel, low-power, low-voltage, bidirectional analog switch designed for portable applications that require minimal power dissipation and low VCC operation. The MAX4661 is specifically designed for use in interface applications such as analog switches, multiplexers, demultiplexers, and low-power control systems.

This part is packaged in a space-saving 28-pin TQFN, with a contact size of 5µm for typically low operating power of 4mW. The MAX4661 has a low-voltage operation down to 1.65V and up to 5.5V. The MAX4661 features typical off-isolation from Type II HB-800 and superior both-side ESD protection ratings of ±1500V HBM (human body model) and ±400V CDM (chargeline discharge). It also has a low on-resistance of 8Ω and low off-resistance of 10Ω, enabling high-volume switch operations using single supply, low-voltage power supplies.

The MAX4661EWE+ is an electronically controlled, pass-transistor analog switch with a low voltage control. This type of switch offers a high switching speed and low on-resistance, which results in efficient operation and reduced power consumption. The device can be used in a wide variety of applications, including audio electronics, communications, automotive, and home and professional applications.

The MAX4661EWE+ has an asynchronous control structure that requires a bidirectional control signal for switching between connected loads. It has four logic inputs, enabling it to mix and switch analog signals between two to four channels on a plane source or receiver. Each of the four control signals can be used to select both the send and receive channels. In addition, the internal protection circuit enables controlled switch-on of the control transistor at turn-on. This guarantees a high on-resistance and thus a high current.

In conclusion, the MAX4661EWE+ is a low power and versatile switch designed to support demanding interface applications in portable devices. The MAX4661EWE+ is designed to provide superior off-isolation and both-side ESD protection to enable robust performance in noisy environments. With its low-voltage operation, low on- and off-resistance, and four logic inputs, the MAX4661EWE+ is ideal for use in applications such as analog switches, multiplexers, and demultiplexers.
