Overview
The ADG1636BCPZ-REEL7, produced by Analog Devices Inc., is a monolithic CMOS device that features two independently selectable single-pole/double-throw (SPDT) switches. This device is designed to operate with various supply voltages, including ±5 V, +12 V, +5 V, and +3.3 V. The ADG1636 is controlled by an EN input, which enables or disables the device, and each switch conducts equally well in both directions when on. The device is packaged in a 16-lead LFCSP (4mm x 4mm with EP) and is suitable for applications requiring low on resistance and minimal power dissipation.
