The ADG636 operates from a dual 2.7 V to 5.5 V supply, or 5. Small 14-lead TSSOP package. from a single supply of +2.7 V to +5.5 V. This switch offers ultralow charge injection of 1.5 pC over the entire signal range and leakage current of 10 pA typical at 25C. In addition, it offers on resistance of 85 typical, which is matched to within 2 between channels. The ADG636 also has low power dissipation yet is capable of high switching speeds. The ADG636 exhibits break-before-make switching action and is available in a 14-lead TSSOP package. Rev. B Information furnished by Analog Devices is believed to be accurate and reliable.
