PARAMETER DESCRIPTION

DESCRIPTION
VCOM
Voltage at COM
VNC
Voltage at NC
VNO
Voltage at NO
ron
Resistance between COM and NC or COM and NO ports when the channel is on
rpeak
Peak on-state resistance over a specified voltage range
Δron
Difference of ron between channels
ron(flat)
Difference between the maximum and minimum value of ron in a channel over the specified range of conditions
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the off state under
INC(OFF)
worst-case input and output conditions
INC(PWROFF)
Leakage current measured at the NC port during the power-down condition, V+ = 0
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the off state under
INO(OFF)
worst-case input and output conditions
INO(PWROFF)
Leakage current measured at the NO port during the power-down condition, V+ = 0
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the on state and the
INC(ON)
output (COM) being open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the on state and the
INO(ON)
output (COM) being open
Leakage current measured at the COM port, with the corresponding channel (COM to NO or COM to NC) in the on
ICOM(ON)
state and the output (NC or NO) being open
ICOM(PWROFF)
Leakage current measured at the COM port during the power-down condition, V+ = 0
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 (IN)
IIH, IIL
Leakage current measured at (IN)
Turn-on time for the switch. This parameter is measured under the specified range of conditions and by the
tON
propagation delay between the digital control (IN) signal and analog outputs (COM, NC, or NO) signal when the
switch is turning on.
Turn-off time for the switch. This parameter is measured under the specified range of conditions and by the
tOFF
propagation delay between the digital control (IN) signal and analog outputs (COM, NC, or NO) signal when the
switch is turning off.
Break-before-make time. This parameter is measured under the specified range of conditions and by the
tBBM
propagation delay between the output of two adjacent analog channels (NC and NO) when the control signal
changes state.
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC, NO,
or COM) output. This is measured in coulomb (C) and measured by the total charge induced due to switching of the
QC
control input. Charge injection, QC = CL × ΔVO, CL is the load capacitance and ΔVO is the change in analog output
voltage.
CNC(OFF)
Capacitance at the NC port when the corresponding channel (NC to COM) is off
CNO(OFF)
Capacitance at the NO port when the corresponding channel (NO to COM) is off
CNC(ON)
Capacitance at the NC port when the corresponding channel (NC to COM) is on
CNO(ON)
Capacitance at the NO port when the corresponding channel (NO to COM) is on
CCOM(ON)
Capacitance at the COM port when the corresponding channel (COM to NC or COM to NO) is on
CIN
Capacitance of (IN)
OFF isolation of the switch is a measurement off-state switch impedance. This is measured in dB in a specific
OISO
frequency, with the corresponding channel (NC to COM or NO to COM) in the off state.
Crosstalk is a measurement of unwanted signal coupling from an on channel to an off channel (NC to NO or NO to
XTALK
NC). This is measured in a specific frequency and in dB.
BW
Bandwidth of the switch. This is the frequency in which the gain of an on channel is –3 dB below the DC gain.
Total harmonic distortion describes the signal distortion caused by the analog switch. This is defined as the ratio or
THD
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
