0.5Ω, Low-Voltage, Single-Supply
SPST Analog Switches
General Description
The MAX4626/MAX4627/MAX4628 are low-on-resis-
tance, low-voltage, single-pole/single-throw (SPST)
analog switches that operate from a +1.8V to +5.5V sin-
gle supply. The MAX4626 is normally open (NO), and
the MAX4627 is normally closed (NC). The MAX4628 is
normally open (NO) and has two control inputs. These
devices also have fast switching speeds (tON = 50ns
max, tOFF = 30ns max).
When powered from a +5V supply, the MAX4626/
MAX4627/MAX4628 offer 0.5Ω max on-resistance
(RON) with 0.1Ω max RON flatness, and their digital
logic inputs are TTL compatible. These switches also
feature overcurrent protection to prevent device dam-
age from short circuits and excessive loads.
The MAX4626 is pin compatible with the MAX4514, and
the MAX4627 is pin compatible with the MAX4515. The
MAX4626/MAX4627 are available in SOT23-5 pack-
ages; the MAX4628 is available in a SOT23-6 package.
