ADG708/ADG709 are low voltage CMOS analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG708 switches one of eight inputs (S1 to S8) to a common output, D, as determined by the 3-bit binary address lines A0, A1, and A2. The ADG709 switches one of four differential inputs (D1 to D4) to a common output, D, as determined by the 2-bit binary address lines A0 and A1. ADG708/ADG709 operate from 1.8V to 5.5V single supply and ±2.5V dual supply, have a 3Ω on resistance, 0.75Ω on resistance flatness, 100pA leakage currents, 14ns switching times, a 16-lead TSSOP package, low power consumption, and TTL/CMOS compatible inputs.
The ADG708 is an 8‑to‑1 single‑ended analog multiplexer, while the ADG709 is a 4‑to‑1 differential multiplexer. Both devices operate from a single 1.8 V to 5.5 V supply or from dual ±2.5 V rails, feature low on‑resistance (typical 3 Ω), low leakage currents (≈100 pA), and fast 14 ns switching. They are supplied in a compact 16‑lead TSSOP package and are designed for low power consumption (<0.01 pW).
Typical applications include data‑acquisition systems, communication equipment, relay replacement, audio/video switching, and battery‑powered portable instruments. The document provides detailed specifications, functional block diagrams, ordering information, and outline dimensions for design integration.
