The MAX4357ECD+TD operates on a single +2.7V to +5.5V power supply, making it ideal for low voltage battery applications. The MAX4357ECD+TD can be used in analog signal switching and buffering from industrial, automotive and consumer applications. The integrated CMOS compatible enable pin ensures high-level, low power performance for a wide range of signal levels.

Application Field

The MAX4357ECD+TD is suitable for multiple applications including:

• High speed SPDT/SP3T signal switching
• USB Ports Hot Plug Applications
• Analog and Digital Video Switching
• Portable Audio Applications
• Analog Signal Multiplexing and Demultiplexing
• Analog Buffer Circuits
• High Speed LCD Display Switching

Working Principle

The MAX4357ECD+TD is a dual/single-pole double throw (SPDT/SP3T) switch designed to provide low on-resistance switching performance and low power consumption in low voltage applications. The switch features an integrated enable pin that can be used to turn on/off the switch output. When high, the outputs will be enabled, allowing for low-on resistance switching. When low, the outputs are disabled and the switch is in a low-power stand-by mode.The switch features a low on-resistance Rds(on), high speed tON/tOFF, and high frequency bandwidth of 30 MHz. This switch is ideal for switching analog signals in high-performance applications, such as digital to analog conversion and analog to digital conversion, audio, video and communication systems.The switch also features a low input capacitance, which makes it ideal for switching digital signals. This low input capacitance allows for low-distortion signal transmission. The devices are offered in single, dual and quad configurations. This allows one device to switch multiple signals. The devices are available in 8-pin TSOP, 10-pin MicroSMT, and 16-pin QSOP packages, allowing for design flexibility and minimal board space utilization.

Conclusion

The MAX4357ECD+TD is a dual-channel complementary switch designed to provide a low on-resistance, wide bandwidth, and low power high performance analog switch solution for a wide range of applications. By offering an integrated CMOS compatible enable pin for high-level, low power performance, the device is suitable for multiple applications including high speed SPDT/SP3T signal switching, USB Ports Hot Plug Applications, Analog and Digital Video Switching, Portable Audio Applications, and Analog Signal Multiplexing and Demultiplexing. The device features a low on-resistance Rds(on), high speed tON/tOFF, and high frequency bandwidth of 30 MHz. The low input capacitance also allows for low-distortion signal transmission. The devices are available in single, dual and quad configurations, and are offered in 8-pin TSOP, 10-pin MicroSMT, and 16-pin QSOP packages.
