ADVANCED LINEAR ALD4201/ALD4202M DEVICES, INC. CMOS LOW VOLTAGE, LOW CHARGE INJECTION QUAD SPST ANALOG SWITCHES GENERAL DESCRIPTION FEATURES 3V, 5V & 10V supply operation The ALD4201/ALD4202M are quad SPST CMOS analog switches speci- 1.5V, 2.5V & 5V supply operation fically developed for 3 to 12 volt applications where low charge injection 0.1W power dissipation and low leakage currents are important analog switch operating 1pC charge injection characteristics. The main features are precision matching, charge Rail-to-rail signal range compensation circuitry, fast switching, low on-resistance and micropower Low on-resistance consumption. The ALD4201 operates in break-before-make switching pA leakage current whereas the ALD4202M operates in make-before-break switching. 4201 break-before-make switching 4202M make-before-break switching The ALD4201/ALD4202M are designed for precision applications such as Built-in dual supply level translator charge amplifiers, sample and hold amplifiers, data converter switches, and programmable gain amplifiers. These switches are also excellent for BENEFITS general purpose switching applications for micropower battery operated Fast effective signal throughput systems. Low switching transients Low signal loss APPLICATIONS INFORMATION Essentially no DC power consumption Full analog signal range over power The ALD4201/ALD4202M are designed to operate with standard single or supply rail dual power supplies of +3V to 10V or 1.5V to 5V. Functionality extends Flexible power supply range for battery down to +2V or 1V power supply, making it suitable for lithium battery or operated systems rechargeable battery operated systems where power efficiency and performance are important design parameters. These switches feature APPLICATIONS nA quiescent current and interface directly to CMOS logic levels from microprocessor or logic interface circuits. Built- in level shifters at the input Low level signal conditioning circuits stage provide for dual supply analog signal switching. On the board level, Portable battery operated instruments low charge injection and fast operation can be obtained by using short Computer peripherals PCMCIA leads, minimizing input and output capacitances, and by adequate Fast sample and hold bypass capacitors placed on the board at the supply nodes.
