Detailed Description
The ISL84684 is a bidirectional, dual single pole/double
throw (SPDT) analog switch that offers precise switching
capability from a single 1.65V to 3.6V supply with low
ON-resistance (0.35
Ω) and high speed operation
(tON =50ns, tOFF = 27ns). The device is especially well
suited for portable battery powered equipment due to its low
operating supply voltage (1.65V), low power consumption
(2.7W max), low leakage currents (60nA max), and its tiny
TDFN and MSOP packages. The ultra low ON-resistance and
rON flatness provide very low insertion loss and distortion to
applications that require signal reproduction.
External V+ Series Resistor
For improved ESD and latch-up immunity, Intersil
recommends adding a 100
Ω resistor in series with the V+
power supply pin of the ISL84684 IC (see Figure 8).
