Overview
The ADG707BRUZ, produced by Analog Devices Inc., is a low-voltage, CMOS analog multiplexer. This device is part of the ADG707 series, which comprises eight differential channels. The ADG707 switches one of eight differential inputs to a common differential output, controlled by 3-bit binary address lines A0, A1, and A2. An enable (EN) input allows the device to be enabled or disabled, with all channels switched off when disabled. The ADG707 is designed for low-power consumption and operates within a supply range of 1.8 V to 5.5 V, making it ideal for battery-powered and portable instruments.
