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.
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. On the board level, low
charge injection and fast operation may be achieved 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 ALD4211/ALD4212/ALD4213 are manufactured with Advanced Linear
Devices enhanced ACMOS silicon gate CMOS process. They are
designed also as linear cell elements in Advanced Linear Devices’
“Function-Specific” ASIC.
