The ADG888 is a low voltage, dual DPDT (double-pole, The ADG888 is available in a 16-ball WLCSP, 16-lead LFCSP, double-throw) CMOS device optimized for high performance and a 16-lead TSSOP. These packages make the ADG888 the audio switching. With its low power and small physical size, it is ideal solution for space-constrained applications. ideal for portable devices.
PRODUCT HIGHLIGHTS
This device offers ultralow on resistance of less than 0.8 Ω over 1. <0.6 Ω over full temperature range of −40°C to +125°C. the full temperature range, making it an ideal solution for 2. High current handling capability (400 mA continuous applications requiring minimal distortion through the switch. current at 5 V). The ADG888 also has the capability of carrying large amounts 3. Low THD + N (0.008% typical). of current, typically 400 mA at 5 V operation. 4. Tiny 16-ball WLCSP, 16-lead LFCSP, and 16-lead TSSOP. When on, each switch conducts equally well in both directions and has an input signal range that extends to the supplies. The ADG888 exhibits break-before-make switching action.
