GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG5412W contains four independent single-pole/single-
throw (SPST) switches. The ADG5412W switches turn on with
Logic 1. Each switch conducts equally well in both directions
when on, and each switch has an input signal range that extends
to the supplies. In the off condition, signal levels up to the
supplies are blocked.
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 ADG5412W can be operated from
dual supplies up to 22 V.
4. Single-supply operation. For applications where the analog
signal is unipolar, the ADG5412W can be operated from a
single rail power supply up to 40 V.
The ADG5412W does not have a VL pin. The digital inputs are
compatible with 3 V logic inputs over the full operating supply
range.
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
devices suitable for video signal switching.
5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
6. No VL logic power supply required.
