The ADG1404 is a CMOS analog multiplexer comprising four single channels designed on an iCMOS® process. iCMOS (industrial CMOS) is a modular manufacturing process that allows multiple functional blocks to be produced on a single chip and provides multiple packaging options. The ADG1404 provides four high-performance, low-power, high-accuracy switch channels that can be used in a variety of applications.
The ADG1404 is a complementary metal‑oxide semiconductor (CMOS) analog multiplexer that provides four single channels in a compact iCMOS process. It offers a very flat on‑resistance profile (1.5 Ω typ) for excellent linearity, ultralow power dissipation (<0.03 µW), and rail‑to‑rail operation. The device can be supplied from ±15 V dual, 12 V single, or 5 V dual configurations, making it suitable for battery‑powered and portable instruments.
Key features include break‑before‑make switching, low charge injection, high off‑isolation (70‑80 dB), and a range of package options (14‑lead TSSOP and 16‑lead LFCSP). Detailed specifications cover on‑resistance, leakage currents, dynamic switching times, and absolute maximum ratings, providing designers with the data needed for high‑performance analog signal routing.
| On‑Resistance (Ron) | 1.5 Ω typ |
|---|---|
| On‑Resistance Flatness | 0.3 Ω typ |
| On‑Resistance Match (Between Channels) | 0.1 Ω typ |
| Maximum Continuous Current (LFCSP) | 140 mA |
| Power‑Down Leakage (Source Off) | 0.03 nA typ |
The typical on‑resistance is 1.5 Ω at a source voltage of +10 V and a test current of –10 mA.
The LFCSP version can handle up to 140 mA of continuous current.
