GENERAL DESCRIPTION
The ADG5208/ADG5209 are monolithic CMOS analog multi-
plexers comprising eight single channels and four differential
channels, respectively. The ADG5208 switches one of eight
inputs to a common output, as determined by the 3-bit binary
address lines, A0, A1, and A2. The ADG5209 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 ultralow
capacitance and charge injection of these switches make them
ideal solutions for data acquisition and sample-and-hold appli-
cations, where low glitch and fast settling are required. Fast
switching speed coupled with high signal bandwidth make
these devices 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 ADG5208/ADG5209 do not have VL pins; instead, 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
to prevent latch-up even under severe overvoltage conditions.
2. 0.4 pC Charge Injection.
3. Dual-Supply Operation.
For applications where the analog signal is bipolar, the
ADG5208/ADG5209 can be operated from dual supplies
of up to ±22 V.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG5208/ADG5209 can be operated from a single rail
power supply of up to 40 V.
5. 3 V Logic-Compatible Digital Inputs.
VINH = 2.0 V, VINL = 0.8 V.
6. No VL Logic Power Supply Required.
