PRELIMINARY TECHNICAL DATA

TERMINOLOGY

Most positive power supply potential.

Positive supply current.

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.

Analog voltage on terminals D, S

Ohmic resistance between D and S.

Flatness is defined as 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 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.

Charge

A measure of the glitch impulse transferred from the digital input to the analog output during switching.

Injection

Off Isolation

A measure of unwanted signal coupling through an “OFF” switch.

Crosstalk

A measure of unwanted signal which is coupled through from one channel to another as a result of parasitic

capacitance.

Bandwidth

The frequency at which the output is attenuated by 3dBs.

On Response The Frequency response of the “ON” switch.

Insertion

The loss due to the ON resistance of the switch.
