Overview
The ADG612YRU, produced by Analog Devices Inc., is a monolithic CMOS device that contains four independently selectable single-pole, single-throw (SPST) switches. These switches are designed to offer ultralow charge injection of 1 pC over the full input signal range and typical leakage currents of 10 pA at 25°C. The device is fully specified for ±5 V, +5 V, and +3 V supplies, making it versatile for various voltage requirements. The ADG612 differs from the ADG611 in that its switches are turned on with a logic high on the appropriate control input, whereas the ADG611 switches are turned on with a logic low.
