PARAMETER DESCRIPTION
DESCRIPTION
Voltage at COM
Voltage at NC
Voltage at NO
Resistance between COM and NC or NO ports when the channel is ON
Difference of r_on between channels in a specific device
Difference between the maximum and minimum value of r_on 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
Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output
(COM) open
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state
Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the ON state and the output
(COM) open
Leakage current measured at the COM port, with the corresponding channel (COM to NC or NO) in the OFF state
Leakage current measured at the COM port, with the corresponding channel (COM to NC or NO) in the ON state and the
output (NC or NO) open
Minimum input voltage for logic high for the control input (IN, EN)
Maximum input voltage for logic low for the control input (IN, EN)
Voltage at the control input (IN, EN)
Leakage current measured at the control input (IN, EN)
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 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 propagation
delay between the digital control (IN) signal and analog output (NC or NO) signal when the switch is turning OFF.
Charge injection is a measurement of unwanted signal coupling from the control (IN) input to the analog (NC or NO)
output. This is measured in coulomb (C) and measured by the total charge induced due to switching of the control input.
Charge injection, Q_C = C_L × ΔV_COM, C_L is the load capacitance and ΔV_COM is the change in analog output voltage.
Capacitance at the NC port when the corresponding channel (NC to COM) is OFF
Capacitance at the NC port when the corresponding channel (NC to COM) is ON
Capacitance at the NC port when the corresponding channel (NO to COM) is OFF
Capacitance at the NC port when the corresponding channel (NO to COM) is ON
Capacitance at the COM port when the corresponding channel (COM to NC) is OFF
Capacitance at the COM port when the corresponding channel (COM to NC) is ON
Capacitance of control input (IN, EN)
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.
Crosstalk is a measurement of unwanted signal coupling from an ON channel to an OFF channel (NC1 to NO1). Adjacent
crosstalk is a measure of unwanted signal coupling from an ON channel to an adjacent ON channel (NC1 to NC2) .This is
measured in a specific frequency and in dB.
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 of root
mean square (RMS) value of the second, third, and higher harmonic to the absolute magnitude of the fundamental
harmonic.
Static power-supply current with the control (IN) pin at V₊ or GND
