LoPro^™ Dual SPDT Analog Switch
Description
ProTek Analog’s PA2222 is a dual high-bandwidth, fast
single-pole double throw (SPDT) CMOS switch. It can be
used as an analog switch or as a low-delay bus switch.
Specified over a operating power supply voltage, 1.8V to
4.2V, the PA2222 has an On-Resistance of 0.6Ω at +2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption
during switching.
The PA2222T includes termination resistors that improve
noise immunity during overshoot excursions and off isolations
or pop-up noise minimization
