1Ω, Low-Voltage, Single-Supply
SPDT Analog Switches
General Description
Features
The MAX4624/MAX4625 are low-on-resistance, low-
voltage single-pole/double-throw (SPDT) analog switch-
es that operate from a single +1.8V to +5.5V supply.
The MAX4624 has break-before-make switching; the
MAX4625 has make-before-break switching. These
