Low on resistance (RON): 4 typical. double-throw (SPDT) switches. Each switch conducts equally 2. Dual 2.7 V to 5.5 V or single 2.7 V to 5.5 V supplies. well in both directions when the device is on. 3. Low power dissipation. 4. Fast t /t . ON OFF The ADG619/ADG620 offer a low on resistance of 4 , which 5. Tiny, 8-lead SOT-23 and 8-lead MSOP. is matched to within 0.7 between channels. These switches also provide low power dissipation, yet result in high switching Table 1. Truth Table for the ADG619/ADG620 speeds. The ADG619 exhibits break-before-make switching IN Switch S1 Switch S2 action, thus preventing momentary shorting when switching 0 On Off channels. The ADG620 exhibits make-before-break action. 1 Off On The ADG619/ADG620 are available in an 8-lead SOT-23 and an 8-lead MSOP. Rev.
