GENERAL DESCRIPTION

The ADG5436 is a monolithic CMOS device containing two

independently selectable single-pole/single-throw (SPDT)

switches. An EN input on the LFCSP package enables or

disables the device. When disabled, all channels switch off. Each

switch conducts equally well in both directions when on and

has an input signal range that extends to the supplies. In the off

condition, signal levels up to the supplies are blocked. Both

switches exhibit break-before-make switching action for use in

multiplexer applications.

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

range, ensuring excellent linearity and low distortion when

switching audio signals.

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.

3. Dual-supply operation. For applications where the analog

signal is bipolar, the ADG5436 can be operated from dual

supplies up to ±22 V.

4. Single-supply operation. For applications where the analog

signal is unipolar, the ADG5436 can be operated from a

single-rail power supply up to 40 V.
