Most negative power supply in a dual supply
application. In single supply applications, this
should be tied to ground.

FLAT(ON)
Flatness is defined as the difference between the
maximum and minimum value of on resistance
as measured over the specified analog signal range.

IN
Digital Input Capacitance
t
ON
Delay time between loading new data to the
shift register and selected switches switching on.
t
OFF
Delay time between loading new data to the
shift register and selected switches switching off.
Off Isolation A measure of unwanted signal coupling through
an “OFF” switch.
Crosstalk A measure of unwanted signal which is coupled
through from one channel to another as a result
of parasitic capacitance.
Charge A measure of the glitch impulse transferred
Injection from the digital input to the analog output
during switching.
Bandwidth The frequency at which the output is attenuated
by –3 dBs.
On Response The frequency response of the “ON” switch.
Insertion Loss The loss due to the ON resistance of the switch.
Insertion Loss = 20 log
