PA2312
LoPro^™ Dual SPDT Analog Switch
Description
ProTek Analog’s PA2312 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 PA2312 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.
