PARAMETER DESCRIPTION
SYMBOL
DESCRIPTION
VCOM
Voltage at COM
VNC
Voltage at NC
ron
Resistance between COM and NC ports when the channel is ON
ron(flat)
Difference between the maximum and minimum value of ron in a channel over the specified range of conditions
INC(OFF)
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the OFF state
INC(ON)
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output (COM)
open
ICOM(OFF)
Leakage current measured at the COM port, with the corresponding channel (COM to NC) in the OFF state
ICOM(ON)
Leakage current measured at the COM port, with the corresponding channel (COM to NC) in the ON state and the output (NC)
open
VIH
Minimum input voltage for logic high for the control input (IN)
VIL
Maximum input voltage for logic low for the control input (IN)
VI
Voltage at the control input (IN)
IIH, IIL
Leakage current measured at the control input (IN)
tON
Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the propagation delay
between the digital control (IN) signal and analog output (COM or NC) signal when the switch is turning ON.
tOFF
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the propagation delay
between the digital control (IN) signal and analog output (COM or NC) signal when the switch is turning OFF.
QC
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC or COM) output.
This is measured in coulomb (C) and measured by the total charge induced due to switching of the control input.
Charge injection, QC = CL × VCOM, CL is the load capacitance, and VCOM is the change in analog output voltage.
CNC(OFF)
Capacitance at the NC port when the corresponding channel (NC to COM) is OFF
CNC(ON)
Capacitance at the NC port when the corresponding channel (NC to COM) is ON
CCOM(OFF)
Capacitance at the COM port when the corresponding channel (COM to NC) is OFF
CCOM(ON)
Capacitance at the COM port when the corresponding channel (COM to NC) is ON
CI
Capacitance of control input (IN)
OISO
OFF isolation of the switch is a measurement of OFF-state switch impedance. This is measured in dB in a specific frequency,
with the corresponding channel (NC to COM) in the OFF state.
BW
Bandwidth of the switch. This is the frequency in which the gain of an ON channel is 3 dB below the DC gain.
THD
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio of root mean
square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of the fundamental harmonic.
I+
Static power-supply current with the control (IN) pin at V+ or GND
