TERMINOLOGY

RON

Ohmic resistance between the D and S terminals.

ΔRON

Difference between the RON of any two channels.

RFLAT(ON)

Flatness is defined as the difference between the maximum and

minimum value of on resistance as measured.

IS (Off)

Source leakage current when the switch is off.

ID (Off)

Drain leakage current when the switch is off.

ID, IS (On)

Channel leakage current when the switch is on.

VD, VS

Analog voltage on Terminal D and Terminal S.

CS (Off)

Channel input capacitance for the off condition.

CD (Off)

Channel output capacitance for the off condition.

CD, CS (On)

On switch capacitance.

CIN

Digital input capacitance.

tON (EN)

Delay time between the 50% and 90% points of the digital input

and the switch on condition.

tOFF (EN)

Delay time between the 50% and 90% points of the digital input

and the switch off condition.

tTRANSITION

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.

tBBM

Off time measured between the 80% points of the switches

when switching from one address state to another.

VINL

Maximum input voltage for Logic 0.

VINH

Minimum input voltage for Logic 1.

IINL, IINH

Input current of the digital input.

IDD

Positive supply current.

ISS

Negative supply current.

Off Isolation

A measure of unwanted signal coupling through an off channel.

Charge Injection

A measure of the glitch impulse transferred from the digital

input to the analog output during switching.

Bandwidth

The frequency at which the output is attenuated by 3 dB.

On Response

The frequency response of the on switch.

THD + N

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 modu-

lated 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.
