GENERAL DESCRIPTION

The ADG5412BF and ADG5413BF
controlled single-pole/single-throw (SPST) switches. The
ADG5412BF has four switches that turn on with Logic 1 inputs.
The ADG5413BF has two switches that turn on and two switches
that turn off with Logic 1 inputs. Each switch conducts equally
well in both directions when on, and each switch has an input
signal range that extends to the supplies. The digital inputs are
compatible with 3 V logic inputs over the full operating supply
range.
When no power supplies are present, the switch remains in the
off condition, and the switch inputs are high impedance. Under
normal operating conditions, if the analog input signal levels on
any switch pin exceed V or V
DD
switch turns off. Input signal levels up to +55 V and −55 V relative
to ground are blocked, in both the powered and unpowered
condition.

The low on resistance of these switches, combined with on-
resistance flatness over a significant portion of the signal range
make them an ideal solution for data acquisition and gain switching
applications where excellent linearity and low distortion are critical.

PRODUCT HIGHLIGHTS

1. Switch pins are protected against voltages greater than the
supply rails, up to −55 V and +55 V.
2. Switch pins are protected against voltages between −55 V
and +55 V, in an unpowered state.
3. Overvoltage detection with digital output indicates
operating state of switches.
4. Trench isolation guards against latch-up.
5. Optimized for low on resistance and on-resistance flatness.
6. The ADG5412BF/ADG5413BF
dual-supply of ±5 V up to ±22 V or a single power supply
of 8 V up to 44 V.
