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. Low RON.
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.
5. 3 V logic-compatible digital inputs: VIH = 2.0 V, VIL = 0.8 V.
6. No VL logic power supply required.
