AME4624/4625
1-Ohm Low Voltage
SPDT Analog Switch
n
General Description
The AME4624/AME4625 analog switches feature low
ON resistance, single-pole, double-throw (SPDT) with
wide operating single power supply voltage range, from
1.8V to 5.5V. The AME4624 offers break-before-make
switching while the AME4625 offers make-before-break
switching.
AME4624/AME4625 has 1Ω max ON resistance when
+5V power supply is used. These products also have
fast switching speeds, t
ON
= t
OFF
= 50nS max.
AME4624/AME4625 are available in SOT-26 & TSOT-
26 (TSOT-23, 6 pins).
