Technical content

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.

The analog switch has ultra low capacitive charge coupling so that the charge stored on a 200pF sampling capacitor is minimally affected. 2. With special charge balancing and charge cancellation circuitry designed on chip, the ALD4211/ALD4212/ ALD4213 achieves ultra low charge injection of typically only 0.2pC resulting in extremely low signal distortion to the external circuit. 3. The analog switch switching transistors have pA leakage currents minimizing the droop rate of the sampling circuit. 4. The internal switch timing allows for the analog switch to turn off internally without producing any residual transistor channel charge injection, which may affect external circuits. With a low loss polystyrene or polypropylene sampling capacitor, long data retention times are possible without significant signal loss. The ALD4211/ALD4212/ALD4213 CMOS analog switches, when used with industry standard pinout connection, have the input and output pins reversed with the signal source input connected to OUT pins and COM pins used as output pins. In this connection and when used with 1,000pF or greater value capacitors, or when connected to a DC current or resistive load, the switch would not be operating in an ultra low charge injection mode. Typical charge injection, in this case, would be 5pC as the pin to pin capacitive coupling effect would dominate. In this connection, all the other characteristics of the ALD4211/ALD4212/ALD4213 CMOS analog switches remain the same.
