PARAMETER DESCRIPTION

SYMBOL

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

∆ron

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

INC(OFF)

Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the OFF state under worst-case

input and output conditions

INO(OFF)

Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the OFF state under worst-case

input and output conditions

INC(ON)

Leakage current measured at the NC port, with the corresponding channel (NC to COM) in the ON state and the output (COM)

being open

INO(ON)

Leakage current measured at the NO port, with the corresponding channel (NO to COM) in the ON state and the output (COM)

being open

ICOM(ON)

Leakage current measured at the COM port, with the corresponding channel (COM to NO or COM to NC) in the ON state and

the output (NC or NO) being open

VIH

Minimum input voltage for logic high for the control input (IN)

VIL

Minimum input voltage for logic low for the control input (IN)

VIN

Voltage at IN

IIH, IIL

Leakage current measured at 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 outputs (COM, NC, or NO) 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 outputs (COM, NC, or NO) signal, when the switch is turning OFF.

tBBM

Break-before-make time. This parameter is measured under the specified range of conditions and by the propagation delay

between the output of two adjacent analog channels (NC and NO), when the control signal changes state.

QC

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 control input.

Charge injection, QC = CL × ∆VO, CL is the load capacitance, and ∆VO is the change in analog output voltage.
