aAM3202 / aAM3203
ULTRA LOW POWER, DUAL-SPDT
CMOS ANALOG SWITCHES
PRODUCT SPECIFICATION
Preliminary Specification
General Description
Pin Configuration
The aAM3202 and aAM3203 are precision CMOS
analog dual-SPDT switches or 2:1 multiplexers offering
low on-resistance of less than 4Ω, with better than 0.4Ω
matching between channels and on-resistance flatness
of less than 1.2Ω over the specified analog input voltage
range. The aAM3202 and aAM3203 have very fast turn-
on switching speed of less than 16nS over the full
operating temperature range of -40°C to 85°C. The
aAM3202 and aAM3203 also consume a minimal
amount of power, making them ideal for portable
equipment.

The aAM3202 and aAM3203 connect 1-of-2 inputs to a
common output by control of a select pin in a dual
configuration. The aAM3202 has an inverted switch logic
compared to the aAM3203. The parts are available in a
10-contact leadless QFN package and operate over the
range from 1.8V to 5.5V.
