PI3A3160C
3.0V, SOTiny™ 0.8Ω Dual SPDT Analog Switch
with -1.0V to 4.2V Operating Range
Features
Description
• Analog Signal Range: -1.0V to V when switch is “ON”
ThePI3A3160Cisahigh-bandwidth,fastDualsingle-poledouble-
throw (SPDT) CMOS switch. It can be used as an analog switch or
as a low-delay bus switch. Specified over a wide operating power
supply voltage range, 1.5V to 4.2V ±10%, the switch has a typical
On-Resistance of 0.8Ω at 3.3V.
CC
• -1.0V Undershoot Protection when switch is “OFF”
• CMOS Technology for Bus and Analog Applications
• Low On-Resistance: 0.8Ω (+3.3V Supply)
• Wide V Range: 1.5V to 4.2V ±10%
CC
Break-before-make switching prevents both switches from being
enabled simultaneously. This eliminates signal disruption during
switching.
• Low Power Consumption : 5µW
• Rail-to-Rail switching throughout Signal Range
• Fast Switching Speed: 50ns max. at 3.3V
• High Off Isolation: –50dB at 1 MHz
Control inputs, IN, tolerates input drive signals up to 3.3V, inde-
pendent of supply voltage.
PI3A3160C is a lower voltage and On-Resistance replacement
for the PI5A3158.
• -45dB (1 MHz) Crosstalk Rejection Reduces Signal Distortion
• Break-Before-Make Switching
• Extended Industrial Temperature Range: –40°C to 85°C
