ADVANCED ALD4211/ALD4212 LINEAR ALD4213 DEVICES, INC. CMOS LOW VOLTAGE HIGH SPEED QUAD PRECISION ANALOG SWITCHES GENERAL DESCRIPTION FEATURES The ALD4211/ALD4212/ALD4213 are quad SPST CMOS analog 3V, 5V and 5V supply operation switches specifically designed for low voltage, high speed applications 0.2pC charge injection where 0.2pC charge injection, 200pf sampling capacitor, and picoamp 200pF sampling capacitor leakage current are important analog switch operating characteristics. pA leakage current These analog switches feature fast switching, low on-resistance and 0.1W power dissipation micropower consumption. High precision Rail to rail signal range TheALD4211/4212/4213 are designed for precision applications such as Low On-resistance charge amplifiers, sample and hold amplifiers, data converter switches, Break-before-make switching 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 Low signal loss from +3V to +12Volts. Functionality extends down to a +2 volt power Essentially no DC power consumption supply making it suitable for lithium battery or rechargeable battery Full analog signal range from rail to rail operated systems where power, efficiency, and performance are Flexible power supply range for battery important design considerations. Break-before-make switching is operated systems guaranteed with single supply operation. The ALD4211/4212/4213 may also be used with dual power supplies from 1.5 to 6 volts. APPLICATIONS With special charge balancing and charge cancellation circuitry on Fast sample and hold chip the ALD4211/ALD4212/ALD4213 were developed for ultra low Computer peripherals charge injection applications. Using a 200pF sampling capacitor, very PCMCIA fast precise signal acquisition may be achieved. With ultra low Low level signal conditioning circuits quiescent current, these switches interface directly to CMOS logic Portable battery operated systems levels from microprocessor or logic circuits. On the board level, low Analog signal multiplexer charge injection and fast operation may be achieved by using short Programmable gain amplifiers leads, minimizing input and output capacitances, and by adequate Switched capacitor circuits bypass capacitors placed on the board at the supply nodes.
