GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG604 is a CMOS analog multiplexer, comprising four single channels. It operates from a dual supply of 2.7 V to 5.5 V, or from a single supply of 2.7 V to 5.5 V. The ADG604 switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines, A0, A1, and EN. A Logic "0" on the EN pin disables the device. The ADG604 offers ultralow charge injection of 1.5 pC over the entire signal range and leakage currents of 10 pA typical at 25C. It offers on resistance of 85 typ, which is matched to within 2 between channels. The ADG604 also has low power dissipation yet gives high switching speeds. The ADG604 is available in a 14-lead TSSOP package.
1. Ultralow Charge Injection (Q INJ: 1.5 pC Typ over the Full Signal Range) 2. Leakage Current <0.5 nA max @ 85C 3. Dual 2.7 V to 5.5 V or Single 2.7 V to 5.5 V Supply 4. Fully Specified to 125C 5. Small 14-Lead TSSOP Package

NOTES 1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time. 2 Overvoltages at EN, A0, A1, S, or D will be clamped by internal diodes. Current should be limited to the maximum ratings given.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG604 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
