Multiplex switch IC -- MAX14724EWP: 1 Circuit IC switch 8:43 Ohms WLP-20

Overview

‌MAX14724EWP is a serial controlled 8:4 full matrix analog multiplexer ‌. It can be powered from a single wide power supply or a dual power supply of ±2.5V, with a wide range of power supply voltages, making it particularly suitable for battery-powered portable devices. All channels are guaranteed to be disconnected before switching, ensuring stable signal transmission. The serial control of the MAX14724EWP can be selected in I2C and SPI modes, both of which provide individual control of each individual switch, and any combination of switches can be applied ‌.

The MAX14724EWP has bidirectional operation and supports full-swing analog signals. All control inputs are 1.6V logic level compatible signals. The MAX14724EWP comes in a small, 20-ball, 2mm x 1.7mm, wafer-level package (WLP).

Application field
