It is designed to offer ultralow on-resistance values of typically.5 Ω. This design makes the AG849 an ideal solution for applications that require minimal distortion through the switch. The AG849 also has the capability of carrying large amounts of current, typically 6 ma at 5 V operation. PROUCT HIGHLIGHTS. Very low on-resistance,.5 Ω typical. 2. Tiny, 6-lead SC7 package. 3. Low power dissipation. The CMOS construction ensures low power dissipation. 4. High current carrying capability. 5. Low TH + noise (.% typ). Each switch of the AG849 conducts equally well in both directions when on. The device exhibits break-before-make switching action, thus preventing momentary shorting when switching channels. The AG849 is available in a tiny, 6-lead SC7 package, making it the ideal candidate for space-constrained applications. Rev.

Truth Table IN Switch Switch On Off Off On 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. Overvoltages at IN, S, or will be clamped by internal diodes. Current should be limited to the maximum ratings given. ES CAUTION ES (electrostatic discharge) sensitive device. Electrostatic charges as high as 4 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ES protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ES precautions are recommended to avoid performance degradation or loss of functionality. Rev. Page 5 of 2
