Description
Low Voltage Operation
Low On-Resistance Ron = 0.35Ω @ 2.7 V
−69 dB OIRR @ 2.7 V, 100 kHz
DFN-10 Package
ESD Protection >2000 V
Latch-Up Current >300 mA (JESD 78)
The PA2535/PA2536 are 0.35Ω dual SPDT analog switches
designed for low voltage applications.
The PA2535/PA2536 has on-resistance matching (less than
0.05Ω @ 2.7 V) and flatness (less than 0.2Ω @ 2.7 V) that is
guaranteed, over the entire voltage range. Additionally, low
logic thresholds make the PA2535/PA2536 an ideal interface
to low voltage DSP control signals.
Benefits





Reduced Power Consumption
High Accuracy
Reduce Board Space
1.8-V Logic Compatible
High Bandwidth
The PA2535/PA2536 has fast switching speed with breakbefore-make guaranteed. In the On condition, all switching
elements conduct equally in both directions. Off-isolation and
crosstalk is −69 dB @ 100 kHz.
The PA2535/PA2536 is built on ProTek Analog's highdensity low voltage CMOS process. An epitaxial layer is built in
to prevent latchup.
Applications


The PA2535/PA2536 contains the additional benefit of
2,000 Volt ESD protections.
Cellular Phones
Speaker Headset Switching Audio and
Video Signal Routing
PCMCIA Cards
Battery Operated Systems


In a space saving DFN-10 lead (Pb)-free package, the
PA2535/PA2536 are high performance, low Ron switches for
battery powered applications.
No lead (Pb) is used in the manufacturing process either
inside the device/package or on the external terminations.
As a committed partner to the community and the
environment, ProTek Analog manufactures this product with
the lead (Pb)-free device terminations.

For analog switching products manufactured in DFN
packages, the lead (Pb)-free "LF" suffix is being used as a
designator. Lead (Pb)-free DFN products purchased at any
time will have either a nickel-palladium-gold device termination
or a 100% matte tin device termination.
