S
(On)
The on switch capacitance, which is measured with reference to
ground.
C

The digital input capacitance.
t
ON
The delay between applying the digital control input and the
output switching on. See Figure 31.
t
OFF
The delay between applying the digital control input and the
output switching off. See Figure 31.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching. See Figure 33.
Off Isolation
A measure of unwanted signal coupling through an off switch.
See Figure 27.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance. See
Figure 28.
Bandwidth
The frequency at which the output is attenuated by 3 dB. See
Figure 29.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
Total Harmonic Distortion + Noise (THD + N)
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental. See Figure 30.
AC Power Supply Rejection Ratio (ACPSRR)
The ratio of the amplitude of signal on the output to the amplitude
of the modulation. This is a measure of the ability of the part to
avoid coupling noise and spurious signals that appear on the supply
voltage pin to the output of the switch. The dc voltage on the device
is modulated by a sine wave of 0.62 V p-p.
