Advanced Linear Devices ALD4201

The ALD4201 operates in break-before-make switching whereas the ALD4202M operates in make-before-break switching. The ALD4201/ALD4202M 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 general purpose switching applications for micropower battery operated systems.

GENERAL DESCRIPTION

The ALD4201/ALD4202M are quad SPST CMOS 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.

APPLICATIONS

INFORMATION The ALD4201/ALD4202M are designed to operate with standard single or dual power supplies of +3V to 10V or ±1.5V to ±5V. Functionality extends down to +2V or ±1V power supply, making it suitable for lithium battery or rechargeable battery operated systems where power efficiency and performance are important design parameters. These switches feature nA quiescent current and interface directly to CMOS logic levels from microprocessor or logic interface circuits. Built- in level shifters at the input stage provide for dual supply analog signal switching. On the board level, low charge injection and fa...
