Overview
The ADG3241BKSZ-500RL7, produced by Analog Devices Inc., is a 2.5 V or 3.3 V single digital switch designed on a low voltage CMOS process. This device is optimized for low power dissipation while offering high switching speed and very low on-resistance. It is particularly suited for applications requiring level translation between different voltage domains, such as 3.3 V to 1.8 V, 3.3 V to 2.5 V, and 2.5 V to 1.8 V. The ADG3241 is available in tiny 6-lead SC70 and SOT-66 packages, making it ideal for space-constrained designs.
