ADG738/ADG739 are CMOS low-voltage 3-wire serially-controlled matrix switches with a 2.7V to 5.5V single supply, 2.5 ohm switch resistance, and 0.75 ohm switch resistance flatness.
The ADG738 and ADG739 are CMOS, low‑voltage, 3‑wire serially‑controlled matrix switches. The ADG738 provides an 8‑channel multiplexer, while the ADG739 offers two 4‑channel multiplexers. Both devices operate from a single 2.7 V to 5.5 V supply and feature low on‑resistance, break‑before‑make switching, and SPI‑compatible serial interfaces.
The datasheet includes detailed electrical specifications, timing characteristics, pin functions, ordering information, absolute maximum ratings, and typical performance graphs. All data are presented for the B‑version temperature range of –40 °C to +85 °C.
