GENERAL DESCRIPTION

The ADG5404F is an analog multiplexer composed of four

single channels with fault protected inputs. The ADG5404F

switches one of the four inputs to a common drain, D, as

determined by the 2-bit binary address lines (A0 and A1). An

enable digital input, EN, is used to disable all the switches. Each

channel 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.

The low on resistance of the ADG5404F, combined with on-

resistance flatness over a significant portion of the signal range,

makes it an ideal solution for data acquisition and gain

switching applications where excellent linearity and low

distortion are critical.

Note that, throughout this data sheet, the dual function pin names

are referenced only by the relevant function where applicable. See

the Pin Configurations and Function Descriptions for full pin

names and function descriptions.

When no power supplies are present, the switch remains in the off

condition, and the channel inputs are high impedance. Under

normal operating conditions, if the analog input signal levels on

any Sx pin exceed V_DDor V_SSby a threshold voltage, V_T, the

channel turns off and that Sx pin becomes high impedance. If

the channel is on, the drain pin reacts according to the drain

response (DR) input pin. If the DR pin is left floating or pulled

high, the drain remains high impedance and floats. If the DR pin

is pulled low, the drain pulls to the exceeded rail. Input signal

levels up to +55 V or −55 V relative to ground are blocked, in

both the powered and unpowered conditions.

PRODUCT HIGHLIGHTS

1. Source pins are protected against voltages greater than the

supply rails, up to −55 V and +55 V.

2. Source 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 ADG5404F operates from a dual supply of 5 V up to

22 V, or a single power supply of 8 V up to 44 V.
