TERMINOLOGY

The positive supply current.

The negative supply current.

The analog voltage on Terminal D and Terminal S.

The ohmic resistance between D and S.

Flatness is defined as the difference between the maximum and

minimum value of on resistance as measured over the specified

analog signal range.

The source leakage current with the switch off.

The drain leakage current with the switch off.

The channel leakage current with the switch on.

The maximum input voltage for Logic 0.

The minimum input voltage for Logic 1.

The input current of the digital input.

The off switch source capacitance, measured with reference to

ground.

The off switch drain capacitance, measured with reference to

ground.

The on switch capacitance, measured with reference to ground.

The digital input capacitance.

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

and switch on condition.

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

and switch off condition.

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.

Off time measured between the 80% point of both switches

when switching from one address state to another.

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.

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

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.
