GENERAL DESCRIPTION

The ADG5404 is a complementary metal-oxide semiconductor

(CMOS) analog multiplexer, comprising four single channels.

The on-resistance profile is very flat over the full analog input

range, ensuring excellent linearity and low distortion when

switching audio signals.

The ADG5404 is designed on a trench process, which guards

against latch-up. A dielectric trench separates the P and N

channel transistors, thereby preventing latch-up even under

severe overvoltage conditions.

The ADG5404 switches one of four inputs to a common output,

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

EN. Logic 0 on the EN pin disables the device. Each switch

conducts equally well in both directions when on and has an

input signal range that extends to the supplies. In the off condi-

tion, signal levels up to the supplies are blocked. All switches

exhibit break-before-make switching action.

PRODUCT HIGHLIGHTS

1.

Trench Isolation Guards Against Latch-Up. A dielectric

trench separates the P and N channel transistors, thereby

preventing latch-up even under severe overvoltage

conditions.

2.

3.

Dual-Supply Operation. For applications where the analog

signal is bipolar, the ADG5404 can be operated from dual

supplies of up to ±22 V.

4.

Single-Supply Operation. For applications where the

analog signal is unipolar, the ADG5404 can be operated

from a single-rail power supply of up to 40 V.

6.

No VL logic power supply required.
