Off Isolation
Off isolation is a measure of unwanted signal coupling through
an off switch.
Charge Injection
Charge injection is a measure of the glitch impulse transferred
from the digital input to the analog output during switching.
Crosstalk
Crosstalk is a measure of unwanted signal that is coupled
through from one channel to another as a result of parasitic
capacitance.
Bandwidth
Bandwidth is the frequency at which the output is attenuated
by 3 dB.
On Response
On response is the frequency response of the on switch.
Insertion Loss
Insertion loss is 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 is represented by THD + N.
AC Power Supply Rejection Ratio (ACPSRR)
ACPSRR is 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.
