TERMINOLOGY

Positive supply current.

Analog voltage on Terminal D and Terminal S.

Ohmic resistance between Terminal D and Terminal 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.

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.

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 through from one

channel to another as a result of parasitic capacitance. This is

specified for two conditions:

•

Adjacent channel, that is, S1A to S2A, S1B to S2B, S3A to

S4A, or S3B to S4B.

•

Adjacent switch, that is, S1A to S1B, S2A to S2B, S3A to

S3B, or S4A to S4B.

−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 signal noise to the

fundamental.
