TERMINOLOGY

Positive supply current.

Analog voltage on Terminal D and Terminal S.

Ohmic resistance between D and S.

Flatness is defined as the difference between the maximum and

minimum value of on resistance as measured.

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 the 90% points of the digital

input and switch on condition.

Delay time between the 50% and the 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

A measure of the glitch impulse transferred from the digital

input to the analog output during on-off switching.

Off Isolation

A measure of unwanted signal coupling through an off switch.

Crosstalk

A measure of unwanted signal that is coupled 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

The ratio of the harmonic amplitudes plus noise of a signal, to

the fundamental.

The measure of the variation in propagation delay between each

channel.

Rise Time Delay

The rise time of a signal is a measure of the time for the signal

to rise from 10% of the ON level to 90% of the ON level. Rise

time delay is the difference between the rise time, measured at

the input, and the rise time, measured at the output.

Fall Time Delay

The fall time of a signal is a measure of the time for the signal to

fall from 90% of the ON level to 10% of the ON level. Fall time

delay is the difference between the fall time, measured at the

input, and the fall time, measured at the output.

Rise-Time-to-Fall-Time Mismatch

This is the absolute value between the variation in the fall time

and the rise time, measured at the output.
