TERMINOLOGY

Positive supply current.

Analog voltage on Terminals D and S.

Ohmic resistance between D and S.

Flatness is the difference between the maximum and minimum

value of on resistance as measured over the specified analog

signal range.

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.

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.

−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 harmonics amplitude plus noise of a signal to

the fundamental.

PSRR

Power Supply Rejection Ratio. This is a measure of the coupling

of unwanted ac signals on the power supply to the switch output

when the supply is not decoupled.
