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.
2. Low RON.
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.
5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
6. No VL logic power supply required.
