ALD4201/ALD4202M
ADVANCED
LINEAR
DEVICES, INC.
GENERAL DESCRIPTION
The ALD4201/ALD4202M are quad SPSTCMOS analog switches speci-
fically 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.
