The MAX14724 is a serial-controlled, 8:4 full-matrix analog multiplexer. The device operates from either a single wide supply or dual ±2.5V supplies. A wide operating range makes the device ideal for battery-powered, portable instruments. All channels guarantee break-before-make switching.

The serial control is selectable between I²C and SPI. Both modes provide individual control of each independent switch so that any combination of switches can be applied. I²C mode provides one address-select pin, allowing for addressing up to two devices on a single bus. The SPI mode includes a DO pin that can be used to daisy-chain multiple devices together with a single select signal.

The MAX14724 features bidirectional operation and can handle rail-to-rail analog signals. All control inputs are 1.6V-logic compatible. This device is available in a small 20-pin, 4mm × 4mm, TQFN and 20-bump, 2mm × 1.7mm, wafer-level package (WLP).
