Analog Devices ADG728/ADG729 Datasheet
The ADG728 is an 8‑channel matrix switch and the ADG729 is a dual 4‑channel matrix switch. Both devices use a 2‑wire serial interface compatible with the ?’C™ standard and can operate from a single 2.7 V to 5.5 V supply. They feature closely matched on‑resistance, break‑before‑make switching, and are offered in a 16‑lead TSSOP package.
Key specifications include a typical on‑resistance of 2.5 Ω, leakage currents as low as 0.01 nA, a bandwidth of up to 100 MHz for the ADG729, and an operating temperature range of –40 °C to +85 °C. An automotive‑qualified version (ADG728W) is also available.
