MAX14724

Serial-Controlled 8:4 Matrix Switch Multiplexer

General Description

Beneﬁts and Features

● Flexible Architecture Enables Ease of Design and Control

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.

• 8:4 Matrix Switch Multiplexer

• Fully Programmable with Simultaneous Updates

• Independent Control of Each Switch

• Serial Control

- I C with Address-Select Pin

- SPI with DO for Daisy-Chain

- 1.6V Logic Compatible

● Low Distortion Switching Improves System

Performance

The serial control is selectable between I C and SPI. Both

modes provide individual control of each independent switch

so that any combination of switches can be applied.

I C 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.

• 1Ω R

(typ) with +5V or ±2.5V Supply

• 0.5Ω R

• 0.2Ω R

Match Between Channels (typ)

Flatness Over Signal Range (typ)

• Low Leakage Current: 5nA at +25°C (typ)

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 x 4mm, TQFN and 20-bump,

2mm x 1.7mm, wafer-level package (WLP).

● Integrated Protection for System Reliability

• ±30kV HBM on NO_ and COM_

• ±15kV IEC 61000-4-2 Air Gap Discharge on NO_

and COM_

• ±10kV IEC 61000-4-2 Contact Discharge on NO_

and COM_

Applications

● Medical Equipment

● Data Acquisition

● High-Integration Multiplexing Reduces Footprint and

System Complexity

• 20 WLP (2mm x 1.7mm)

● Signal Switching

• 20 TQFN (4mm x 4mm)

● Battery-Powered Equipment
