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).
