C
The on switch capacitance, measured with reference to ground.
C
The digital input capacitance.
t
Delay time between the 50% and 90% points of the digital input
and switch on condition. See Figure 23.
t
Delay time between the 50% and 90% points of the digital input
and switch off condition. See Figure 23.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching. See Figure 24.
Off Isolation
A measure of unwanted signal coupling through an off switch.
See Figure 25.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
See Figure 26.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch. See Figure 26.
THD + N
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental. See Figure 27.
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 the
signal on the output to the amplitude of the modulation is the
ACPSRR. See Figure 19.
