MAX4751 Datasheet, PDF (1/13 Pages) Maxim Integrated Products – 0.9Ω, Low-Voltage, Single-Supply Quad SPST Analog Switches

19-2421; Rev 1; 4/03
0.9Ω, Low-Voltage, Single-Supply Quad SPST
Analog Switches
General Description
Features
The MAX4751/MAX4752/MAX4753 are low on-resistance,
low-voltage, quad, single-pole/single-throw (SPST) analog
switches that operate from a single +1.6V to +3.6V sup-
ply. These devices have fast switching speeds (t_ON =
30ns, t_OFF = 25ns), handle Rail-to-Rail^® analog signals,
and consume less than 1µW of quiescent power. The
MAX4753 has break-before-make switching.
o Low R_ON
0.9Ω max (+3V Supply)
2.5Ω max (+1.8V Supply)
o On-Resistance Flatness: 0.1Ω max (+3V)
o R_ON Matching
0.12Ω max (+3V Supply)
0.25Ω max (+1.8V Supply)
When powered from a +3V supply, the MAX4751/
MAX4752/MAX4753 feature low 0.9Ω (max) on-resis-
tance (R_ON), with 0.12Ω (max) R_ON matching and 0.1Ω
(max) R_ON flatness. The digital input is 1.8V CMOS
compatible when using a single +3V supply.
The MAX4751 has four normally open (NO) switches,
the MAX4752 has four normally closed (NC) switches,
and the MAX4753 has two NO and two NC switches.
The MAX4751/MAX4752/MAX4753 are available in
3mm ✕ 3mm, 16-pin QFN and 14-pin TSSOP packages.
o +1.6V to +3.6V Single-Supply Operation
o Available in 16-Pin QFN and 3mm ✕ 3mm
Packages
o 1.8V CMOS Logic Compatible (+3V Supply)
o High Current-Handling Capacity (100mA
Continuous)
o Fast Switching: t_ON = 30ns, t_OFF = 25ns
