GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The ADG528F¹is a CMOS analog multiplexer, with the

comprising eight single channels. This multiplexer provides

fault protection. Using a series n-channel, p-channel, n-channel

MOSFET structure, both device and signal source protection is

provided in the event of an overvoltage or power loss. The

multiplexer can withstand continuous overvoltage inputs

from −40 V to +55 V. During fault conditions, the multiplexer

input (or output) appears as an open circuit and only a few

nanoamperes of leakage current will flow. This protects not

only the multiplexer and the circuitry driven by the multiplexer,

but also protects the sensors or signal sources that drive the

multiplexer.

1. Fault protection.

The ADG528F can withstand continuous voltage inputs

from −40 V to +55 V. When a fault occurs due to the

power supplies being turned off, all the channels are turned

off and only a leakage current of a few nanoamperes flows.

2. On channel turns off while fault exists.

3. Low R_ON

4. Fast switching times.

5. Break-before-make switching.

Switches are guaranteed break-before-make so that input

signals are protected against momentary shorting.

6. Trench isolation eliminates latch-up.

A dielectric trench separates the p-channel and n-channel

MOSFETs thereby preventing latch-up.

The ADG528F switches one of eight inputs to a common output

as determined by the 3-bit binary address lines A0, A1, and A2.

The ADG528F has on-chip address and control latches that

facilitate microprocessor interfacing. An EN input on the device

is used to enable or disable the device. When disabled, all channels

are switched off.
