Overview
The ADG608BNZ is a high-performance analog multiplexer produced by Analog Devices Inc. This device is part of the ADG608 series, which includes monolithic CMOS analog multiplexers. The ADG608BNZ is specifically designed to switch one of eight single channels to a common output, controlled by 3-bit binary address lines A0, A1, and A2. It also features an enable input (EN) that allows the device to be enabled or disabled, with all channels switched off when disabled. The device is fabricated on an enhanced LC2MOS process, ensuring low power dissipation, high switching speed, and low on-resistance.
