This device offers ultralow on resistance of less than.82 Ω over the full temperature range. The AG858 is fully specified for 4.2 V to 5.5 V and 2.7 V to 3.6 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 AG858 exhibits break-before-make switching action. The AG858 is available in a 2.1 mm 2.1 mm, 16-lead mini LFCSP. This tiny package makes the part ideal for spaceconstrained applications, such as handsets, PAs, and MP3s. PROUCT HIGHLIGHTS 1. <.82 Ω over the full temperature range of 4 C to +85 C. 2. Single 1.8 V to 5.5 V operation. 3. Compatible with 1.8 V CMOS logic. 4. High current handling capability (25 ma continuous current per channel). 5. Low TH + N:.6% typical mm 2.1 mm, 16-lead mini LFCSP. Rev.
