ADVANCED LINEAR DEVICES, INC.
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.
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.
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 fast operation can be obtained by using short leads, minimizing input and output capacitances, and by adequate bypass capacitors placed on the board at the supply nodes. For more information, see Application Note AN4200.
The ALD4201/4202M are manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process, and are also part of the linear elements in Advanced Linear Devices' "Function-Specific" ASIC.

Notes:
1. Voltage on any terminal must be less than (V+) + 0.3V and greater than (V-) - 0.3V, at all times including before power is applied and V+ = V- = 0.0V. Vsupply power supply needs to be sequenced on first on power turn-on and sequenced off last during power turn-off. 2. See Switching Time Test Circuit. 3. Guaranteed by design . 4.
