TERMINOLOGY

IDD

IDD is the positive supply current.

ISS

ISS is the negative supply current.

VD, VS

VD and VS are the analog voltages on Terminal D and Terminal

S, respectively.

RON

RON is the ohmic resistance between Terminal D and Terminal

∆RON

∆RON is the difference between the RON of any two channels.

RFLAT(ON)

RFLAT(ON) is flatness that is defined as the difference between the

maximum and minimum value of on resistance measured over

the specified analog signal range.

IS (Off)

IS (Off) is the source leakage current with the switch off.

ID (Off)

ID (Off) is the drain leakage current with the switch off.

ID (On), IS (On)

ID (On) and IS (On) are the channel leakage currents with the

switch on.

VINL

VINL is the maximum input voltage for Logic 0.

VINH

VINH is the minimum input voltage for Logic 1.

IINL, IINH

IINL and IINH are the low and high input currents of the digital

inputs.

CD (Off)

CD (Off) is the off switch drain capacitance, which is measured

with reference to the GND pin.

CS (Off)

CS (Off) is the off switch source capacitance, which is measured

with reference to the GND pin.

CD (On), CS (On)

CD (On) and CS (On) are the on switch capacitances, which are

measured with reference to the GND pin

CIN

CIN is the digital input capacitance.

tON

tON is the delay between applying the digital control input and

the output switching on.

tOFF

tOFF is the delay between applying the digital control input and

the output switching off.

tD is the off time measured between the 80% point of both

switches when switching from one address state to another.

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)

THD + N is the ratio of the harmonic amplitude plus the noise

of the signal to the fundamental.

AC Power Supply Rejection Ratio (AC PSRR)

AC PSRR 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 device 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.
