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.

FEATURES
• 3V, 5V & 10V supply operation
• ±1.5V, ±2.5V & ±5V supply operation
• 0.1µW power dissipation
• 1pC charge injection
• Rail-to-rail signal range
• Low on-resistance
• pA leakage current
• 4201 break-before-make switching
• 4202M make-before-break switching
• Built-in dual supply level translator
