GENERAL DESCRIPTION

The ALD4201/ALD4202M are quad SPSTCMOS analog switches specifically developed for 3 to 12 volt applications where low charge injection and low leakage currents are important analog switch operating

characteristics. The main features are precision matching, charge compensation circuitry, fast switching, low on-resistance and micropower consumption. The ALD4201 operates in break-before-make switching whereas the ALD4202M operates in make-before-break switching.
