TERMINOLOGY
IDD
The positive supply current.
ISS
The negative supply current.
VD (VS)
The analog voltage on Terminal D and Terminal S.
RON
The ohmic resistance between Terminal D and Terminal S.
RFLAT(ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance, as measured over the specified
analog signal range.
IS (Off)
The source leakage current with the switch off.
ID (Off)
The drain leakage current with the switch off.
ID, IS (On)
The channel leakage current with the switch on.
VINL
The maximum input voltage for Logic 0.
VINH
The minimum input voltage for Logic 1.
IINL (IINH)
The input current of the digital input.
CS (Off)
The off switch source capacitance, measured with reference
to ground.
CD (Off)
The off switch drain capacitance, measured with reference
to ground.
CD, CS (On)
The on switch capacitance, measured with reference to ground.
CIN
The digital input capacitance.
tON
The delay between applying the digital control input and the
output switching on (see Figure 26).
tOFF
The delay between applying the digital control input and the
output switching off (see Figure 26).
tBBM
Off time or on time measured between the 90% points of both
switches, when switching from one address state to another
(ADG1223 only).
QINJ (Charge Injection)
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
–3 dB Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch.
THD + N (Total Harmonic Noise Plus Distortion)
The ratio of the harmonic amplitude plus noise of the signal to
the fundamental.
ACPSRR (AC Power Supply Rejection Ratio)
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.
