The ADG633 is a low voltage CMOS device comprising three independently selectable SPDT (single pole double throw) switches. They are fully specified for ±5 V, +5 V, and +3 V supplies. The ADG633 switches are turned on with VDD and VDD and through two independent inputs the switch is put in the on or off state. When Vin is higher than Vref, switch 1 is turned on, when Vin is lower than Vref, switch 2 is turned on. All three switches can be turned on or off simultaneously.
The ADG633 is a low‑voltage CMOS triple SPDT switch offered by Analog Devices. It supports dual‑supply operation (+5 V/+5 V/+3 V) or a single supply from 2 V to 12 V, provides break‑before‑make switching, and features TTL/CMOS compatible inputs.
The device is available in 16‑lead TSSOP and 4 mm × 4 mm chip‑scale packages and is suited for automotive, data‑acquisition, battery‑powered, communication, audio/video routing, and industrial control applications. Key specifications include low leakage (<0.2 nA), typical power consumption below 0.1 pW, and operation over –40 °C to +125 °C.
| Supply Voltage Range | 2 V to 12 V (single) / +5 V/+5 V/+3 V (dual) |
|---|---|
| On‑Resistance (Ron) | ≈0.5 Ω typ |
| Off‑State Leakage Current | < 0.2 nA |
| Typical Power Consumption | < 0.1 pW |
| Operating Temperature Range | -40 °C to +125 °C (automotive) / -40 °C to +85 °C (industrial) |
