TERMINOLOGY
RON
Ohmic resistance between D and S.
RFLAT (ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured.
IS (OFF)
Source leakage current with the switch off.
ID (OFF)
Drain leakage current with the switch off.
ID, IS (ON)
Channel leakage current with the switch on.
VD (VS)
Analog voltage on Terminal D and Terminal S.
CS (OFF)
Off switch source capacitance. Measured with reference to
ground.
CD (OFF)
Off switch drain capacitance. Measured with reference to
ground.
CD, CS (ON)
On switch capacitance. Measured with reference to ground.
tON
Delay time between the 50% and the 90% points of the digital
tOFF
Delay time between the 50% and the 90% points of the digital
input and switch off condition.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during on-off switching.
Bandwidth
The frequency at which the output is attenuated by 3 dB.
On Response
The frequency response of the on switch.
On Loss
The voltage drop across the on switch as how many dBs the
signal is away from 0 dB at very low frequencies. See
Figure 10.
