t
Delay time between the 50% and 90% points of the digital input
and switch on condition. See Figure 26.
t
Delay time between the 50% and 90% points of the digital input
and switch off condition. See Figure 26.
t
Delay time between the 50% and 90% points of the digital
inputs and the switch on condition when switching from one
address state to another.
T
Off time measured between the 80% point of both switches
when switching from one address state to another. See Figure 27.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching. See Figure 28.
Off Isolation
A measure of unwanted signal coupling through an off switch.
See Figure 29.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance. See
Figure 30.
Bandwidth
The frequency at which the output is attenuated by 3 dB. See
Figure 31.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch. See Figure 31.
THD + N
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental. See Figure 32.
AC Power Supply Rejection Ratio (ACPSRR)
ACPSRR measures the ability of a 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. The ratio of the amplitude of signal on
the output to the amplitude of the modulation is the ACPSRR.
See Figure 22.
