ADG636:  1 pC Charge Injection, 100 pA Leakage, CMOS, ±5 V/+5 V/+3 V Dual SPDT Switch

Product Details

The ADG636 is a monolithic device, comprising two indepen-dently selectable CMOS single pole, double throw (SPDT) switches. When on, each switch conducts equally well in both directions.

The ADG636 operates from a dual ±2.7 V to ±5.5 V supply, or 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 25°C. In addition, it offers on resistance of 85 Ω typical, which is matched to within 2 Ω 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.
