CMOS Analog Switch
General Description
The MAX4644 is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +1.
8V to +5.
5V.
It provides low 4Ω on-resistance (RON) as well as 1Ω RON flatness over the entire analog signal range.
The MAX4644 offers fast switching times of less than 20ns while ensuring break-before-make operation.
It typically consumes only 0.
01µW of quiescent power, making it suitable for use in low-power, portable applications.
The MAX4644’s features include low leakage currents over the entire temperature range, TTL/
CMOS-compatible digital logic, and excellent AC characteristics.
It is ...
