The ADG5462F contains four channels that are overvoltage protected. The channel protector is placed in series with the signal path and protects sensitive components from overvoltage faults in that path. The channel protector prevents overvoltages when powered and unpowered, and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages.

When no power supplies are present, the channel 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 positive fault voltage (POSFV) or negative fault voltage (NEGFV) by a threshold voltage (V_T), the channel turns off and that Sx pin becomes high impedance. If the DR pin is driven low, the drain pin (Dx) is pulled to the secondary supply voltage that was exceeded. The output profile for each DR voltage level is shown in Figure 1. Input signal levels up to −55 V or +55 V relative to ground are blocked in both the powered and unpowered conditions.

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

Product Highlights

Source pins are protected against voltages greater than the secondary supply rails (POSFV and NEGFV), up to −55 V and +55 V.
In an unpowered state, source pins (Sx) are protected against voltages from −55 V to +55 V.
Overvoltage detection with digital output indicates operating state of channel.
Trench isolation guards against latch-up.
Optimized for low on-resistance and on-resistance flatness.
The ADG5462F operates from a dual power supply range of ±5 V to ±22 V or a single power supply range of 8 V to 44 V.

Product Details

The EVAL-ADG5462FEBZ is the evaluation board for the ADG5462F, which features four channels that are overvoltage protected. The channel protector is placed in series with the signal path and is protected against signals up to −55 V and +55 V in both the powered and unpowered states.

The ADG5462F is soldered to the center of the evaluation board, and screw terminals are provided to connect to each of the source and drain pins. Three screw terminals are used to power the device, with a fourth terminal used to provide a user defined digital voltage, if required. Alternatively, a low dropout (LDO) regulator is provided for 5 V digital voltage control and to supply the LED, which is mounted to provide visual indication of the fault status of the switch.

Full specifications on the ADG5462F are available in the product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
