Internal Oscillator Frequency

The internal oscillator frequency is the value of the on-board

oscillator that drives the gate control chip of the ADGM1304.

Internal Oscillator Feedthrough

The internal oscillator feedthrough is the amount of internal

oscillator signal that feeds through to the RF pins of the switch.

This signal appears as a noise spur on the RFx pin and RFC pin

of the switch at the oscillator operating frequency and oscillator

harmonics.

On Resistance (RON)

RON is the resistance of a switch in the closed (on) state

measured between the package pins. Measure on resistance in

4-wire mode to eliminate any cabling or PCB series resistances.

On Resistance Drift

On resistance drift is the change in the on resistance of the

switch over the specified criteria in Table 1.

Continuously on Lifetime

The continuously on lifetime measures how long the switch is

left in a continuously on state. If the switch is left in the on

position for an extended period, it affects the turn off

mechanism of the device.

Actuation Lifetime

Actuation lifetime is the number of consecutive open to close to

open cycles that can complete without the on resistance

exceeding a specified limit and no occurrence of failures to

open (FTO) or failures to close (FTC).

Cold Switching

Cold switching operates the switch in a mode so that no voltage

differential exists between source and drain when the switch is

closed or no current is flowing from source to drain when the

switch opens. All switches have longer lives when cold

switched.

Hot Switching

Hot switching is operating the switch in a mode where a voltage

differential exists between source and drain when the switch is

closed and/or current is flowing from RFx channel to RFC

channel when the switch is opened. Hot switching results in a

reduced switch life, depending on the magnitude of the open

circuit voltage between the source and the drain.

Input High Voltage (VINH)

VINH is the minimum input voltage for Logic 1.

Input Low Voltage (VINL)

VINL is the maximum input voltage for Logic 0.

Input Current (IINL, IINH)

IINL and IINH are the low and high input currents of the digital

inputs.

Output High Voltage (VOH)

VOH is the minimum output voltage for Logic 1.

Output Low Voltage (VOL)

VOL is the maximum output voltage for Logic 0.

Low Power Mode Current (IDDEXTVCP)

IDD EXT VCP is the amount of supply current used by the gate

driver circuity when the internal oscillator and the charge

pump circuitry are turned off by setting the EXTD_EN pin

high.

External Drive Current (ICPEXTVCP)

ICP EXT VCP is the amount of current used by the ADGM1304

from the external 80 V power supply when the internal

oscillator and charge pump circuitry are turned off by setting the

EXTD_EN pin high.
