DUAL 15-
SPDT ANALOG SWITCH
SCDS252 – JULY 2007
PARAMETER DESCRIPTION (continued)
SYMBOL
DESCRIPTION
OFF isolation of the switch is a measurement of 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. OFF isolation, OISO = 20 LOG
(VNC/VCOM) dB, VCOM is the input and VNC is the output.
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 at a specific frequency and in dB. Crosstalk, XTALK = 20 log (VNC1/VNO1), VNO1 is the input and
VNC1 is the output.
Bandwidth of the switch. This is the frequency where the gain of an ON channel is –3 dB below the dc gain. Gain is
BW
measured from the equation, 20 log (VNC/VCOM) dB, where VNC is the output and VCOM is the input.
I+
Static power-supply current with the control (IN) pin at V+ or GND
ΔI+
This is the increase in I+ for each control (IN) input that is at the specified voltage, rather than at V+ or GND.
