A4722
QUAD SPDT ANALOG SWITCH
0.4Ω , LOW VOLTAGE ,WIDE POWER SUPPLY RANGE
DESCRIPTION
FEATURES
The A4722 is a Dual Wide-Bandwidth, fast single-pole
double-throw(SPDT) CMOS switch featuring an
On-Resistance of 0.4 ohm at VDD=2.7V and wide
power supply range from 1.6V to 4.2V.
The A4722 can be used as an analog switch or as a
low-delay bus switch.
Break-before-make function for both parts eliminates
signal disruption during switching from preventing both
switches being enabled simultaneously.
Wide Power Supply Range:1.6V to 4.2V
Low On-Resistance: 0.4Ω (VDD=2.7V)
Low On-Resistance Flatness
-3dB Bandwidth: 42 MHz
Fast Switching Speed(VDD=3.3V):
tON: 20ns
tOFF:10ns
IDD = 300nA @ TA = +25°C
High Off Isolation: -65dB
Crosstalk Rejection: -65dB
Available in QFN16(3x3)
The A4722 is available in QFN16(3x3).

Notes:
(1) Guaranteed by design. Resistance measurement do not include test circuit or package resistance
(2) Flatness is defined as the difference between the maximum and minimum value of on resistance as measured over the
specified analog signal ranges.
