描述 Description

GENERAL DESCRIPTION
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.
TheALD4211/4212/4213 are designed for precision applications such as charge amplifiers, sample and hold amplifiers, data converter switches, and programmable gain amplifiers. These switches are also excellent for low voltage micropower general purpose switching applications.FEATURES
