ALD4211/ALD4212
ALD4213
CMOS LOW VOLTAGE HIGH SPEED QUAD PRECISION ANALOG SWITCHES
GENERAL DESCRIPTION
FEATURES
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.
• 3V, 5V and ±5V supply operation
• 0.2pC charge injection
• 200pF sampling capacitor
• pA leakage current
• 0.1µW power dissipation
• High precision
• Rail to rail signal range
• Low On-resistance
• Break-before-make switching
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.
BENEFITS
APPLICATIONS INFORMATION
• Five times faster signal capture
• Low switching transients
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.
• Low signal loss
• Essentially no DC power consumption
• Full analog signal range from rail to rail
• Flexible power supply range for battery
operated systems
APPLICATIONS
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.
