The MAX4053CSE+ is a monolithic CMOS analog multiplexer/demultiplexer designed for switching of analog or digital signals in a wide range of applications. With a single voltage supply and low power consumption, the MAX4053CSE+ is ideal for portable and battery-powered applications. It offers a broad selection of switch configurations, plus a wide operating range of power supplies for the best versatility.

The MAX4053CSE+ is an ideal solution for any application that needs to switch analog signals between two or more points, including analog-to-digital or digital-to-analog converters, audio applications, and signal multiplexing. The low off-state resistance and less-than-1dB R-C matching makes it perfect for creating low noise, wide dynamic range signal paths. Plus, it features a low power-on resistance, making it ideal for applications where signal levels are sensitive to switching noise.

The MAX4053CSE+ is a versatile device, operating with a wide range of signal levels and power supplies. With a single voltage supply of 2.7V-10V, it can switch analog signals up to ±3.5V peak. It also features an integrated charge pump that doubles the power supply voltage as needed, allowing the device to switch signals up to ±7V peak.

At the heart of the MAX4053CSE+ is a switch array consisting of eight single-pole double-throw switches, with four switches in parallel. Each switch has an associated control bit that can be used to either switch a signal on or off. These switches are operated using TTL/CMOS logic levels and provide low on-state resistance and high off-state resistance. To control the switches, the MAX4053CSE+ includes a dual-channel serial interface controlled through I2C commands. The MAX4053CSE+ can also be daisy-chained to other devices for greater control.

The MAX4053CSE+ also provides an active-low Chip Enable pin that can be used to disable the device and reduce power consumption. The IC provides an output enable pin for further control of the device. This can be used to isolate the output from the chip’s internal circuitry, preventing any floating signals from propagating through the chip.

The MAX4053CSE+ can also be used to switch digital signals. With the proper selection of switches and resistors, it can be used to route data signals between logic families with different logic levels and rise times. It also features an anti-fuse configuration that allows the device to be used as a programmable multiplexer, allowing users to create custom switch configurations.

Overall, the MAX4053CSE+ is an ideal solution for applications that require low noise and high dynamic range. With its wide range of features and low power consumption, it provides an excellent fit for both analog and digital switching requirements in portable and battery-powered applications.
