APPLICATIONS

The ADG841 and ADG842 are low voltage CMOS devices containing a single-pole, single-throw (SPST) switch. The ADG841 is closed for a Logic 1 input and the ADG842 is open for a Logic 1 input. The devices offer ultralow on resistance of less than 0.48 Ω over the full temperature range. The ADG841/ ADG842 are fully specified for 3.3 V, 2.5 V, and 1.8 V supply operation. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. The ADG841/ADG842 exhibit break-before-make switching action. The ADG841/ADG842 are available in a 6-lead SC70 package. PRODUCT HIGHLIGHTS 1. <0.48 Ω over full temperature range of –40°C to +125°C. 2. Compatible with 1.8 V CMOS logic. 3. High current handling capability (300 mA continuous current at 3.3 V). 4. Low THD + N (0.02% typ). 5. Tiny SC70 package. Table 1. ADG841/ADG842 Truth Table

Current should be limited to the maximum ratings given. 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 indicated in the operational section 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. ESD CAUTION ESD (electrostatic discharge) se nsitive device . Electrostatic charges as hi gh as 4000 V readily accumulate on the human body and test eq uipment and can discharge without detection. Although this product features proprietary ESD protection circ uitry, permanent dama ge may occur on devices subjected to high energy electrostatic di scharges. Ther efore, pro per ESD precautions are rec ommended to avoid performan ce degradation or loss of functionality.
