Advanced Linear Devices ALD4212

The ALD4211/ALD4212/ALD4213 are quad SPST CMOS analog switches specifically designed for low voltage, high speed applications where 0.2pC charge injection, 200pf sampling capacitor, and picoamp leakage current are important analog switch operating characteristics. These analog switches feature fast switching, low on-resistance and micropower consumption. These switches are also excellent for low voltage micropower general purpose switching applications.

GENERAL DESCRIPTION

TheALD4211/4212/4213 are designed for precision applications such as charge amplifiers, sample and hold amplifiers, data converter switches, and programmable gain amplifiers.

APPLICATIONS

INFORMATION The ALD4211/4212/4213 operate with a standard single power supply from +3V to +12Volts. Functionality extends down to a +2 volt power supply making it suitable for lithium battery or rechargeable battery operated systems where power, efficiency, and performance are important design considerations. Break-before-make switching is guaranteed with single supply operation. The ALD4211/4212/4213 may also be used with dual power supplies from ±1.5 to ±6 volts. With special charge balancing and charge cancellation circuitry on chip the ALD4211/ALD4212/ALD4213 were developed for ultra low charge injection applications. Using a 200pF sampling capacitor, very fast precise signal acquisition may be achieved. With ultra low quiescent current, these switches interface directly to CMOS logic levels from microprocessor or logic circuits.
