When on, each switch conducts equally well in both directions. 1. Ultralow Charge Injection (QINJ: ± 1.5 pC typ over full signal range) The ADG636 operates from a dual ± 2.7 V to ± 5.5 V supply, or from a single supply of +2.7 V to +5.5 V. This switch offers ultralow charge injection of ± 1.5 pC over the entire signal range and leakage current of 10 pA typical at 25°C. It offers on-resistance of 85 Ω typ, which is matched to within 2 Ω between channels. The ADG636 also has low power dissipation yet gives high switching speeds. 2. Leakage Current <0.25 nA max @ 85°C 3. Dual ± 2.7 V to ± 5 V or Single +2.7 V to +5.5 V Supply 4. Automotive Temperature Range: –40°C to +125°C 5. Small 14-Lead TSSOP Package The ADG636 exhibits break-before-make switching action and is available in a 14-lead TSSOP package.

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.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG636 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. REV. 0 –5– WARNING!
