TERMINOLOGY

Positive supply current.

Analog voltage on Terminal D and Terminal S.

Ohmic resistance between Terminal D and Terminal S.

The difference between the maximum and minimum values of

on resistance as measured on the switch.

On resistance match between any two channels.

Source leakage current with the switch off.

Drain leakage current with the switch off.

Channel leakage current with the switch on.

Maximum input voltage for Logic 0.

Minimum input voltage for Logic 1.

Input current of the digital input.

Off switch source capacitance. Measured with reference

to ground.

Off switch drain capacitance. Measured with reference

to ground.

On switch capacitance. Measured with reference to ground.

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.

On or off time measured between the 80% points of both

switches when switching from one to another.

Charge Injection

Measure of the glitch impulse transferred from the digital input

to the analog output during on/off switching.

Off Isolation

Measure of unwanted signal coupling through an off switch.

Crosstalk

Measure of unwanted signal that is coupled from one channel to

another as a result of parasitic capacitance.

−3 dB Bandwidth

Frequency at which the output is attenuated by 3 dB.

On Response

Frequency response of the on switch.

Insertion Loss

The loss due to the on resistance of the switch.

THD + N

Ratio of the harmonics amplitude plus noise of a signal to the

fundamental.

The measure of the variation in propagation delay between each

channel.
