GENERAL DESCRIPTION
The ADG5408/ADG5409 are monolithic CMOS analog multi-
plexers comprising eight single channels and four differential
channels, respectively. The ADG5408 switches one of eight
inputs to a common output, as determined by the 3-bit binary
address lines, A0, A1, and A2. The ADG5409 switches one of
four differential inputs to a common differential output, as
determined by the 2-bit binary address lines, A0 and A1.
An EN input on both devices enables or disables the device.
When EN is disabled, all channels switch off. The on-resistance
profile is very flat over the full analog input range, which ensures
good linearity and low distortion when switching audio signals.
High switching speed also makes the parts suitable for video
signal switching.
Each switch conducts equally well in both directions when on,
and each switch has an input signal range that extends to the
power supplies. In the off condition, signal levels up to the
supplies are blocked.
The ADG5408/ADG5409 do not have V
L
pins; rather, the logic
power supply is generated internally by an on-chip voltage
generator.
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 R
ON
.
3. Dual-supply operation. For applications where the analog
signal is bipolar, the ADG5408/ADG5409 can be operated
from dual supplies up to ±22 V.
4. Single-supply operation. For applications where the analog
signal is unipolar, the ADG5408/ADG5409 can be operated
from a single rail power supply up to 40 V.
5. 3 V logic compatible digital inputs: V
INH

INL

6. No V
