TERMINOLOGY

Most positive power supply potential.

GND

Ground (0 V) reference.

S

Source terminal. May be an input or output.

D

Drain terminal. May be an input or output.

IN

Logic control input.

Ohmic resistance between D and S.

Flatness is defined as the difference between

the maximum and minimum value of on resis-

tance 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.”

Analog voltage on terminals D and S.

“OFF” switch source capacitance.

“OFF” switch drain capacitance.

“ON” switch capacitance.

Delay between applying the digital control

input and the output switching on. See Test

Circuit 4.

Delay between applying the digital control

input and the output switching off.

Off Isolation

A measure of unwanted signal coupling

through an “OFF” switch.

Charge

A measure of the glitch impulse transferred from

Injection

the digital input to the analog output during

switching.

Bandwidth

The frequency at which the output is attenu-

ated by –3 dBs.

On Response

The frequency response of the “ON” switch.

Insertion Loss

Loss due to the ON resistance of the switch.

Maximum input voltage for Logic “0.”

Minimum input voltage for Logic “1.”

Input current of the digital input.

Positive supply current.
