Introduces the characteristics of DG417/DG418/DG419, including the types of switches, application scenarios, switch times, and supply voltages.
The DG417, DG418, and DG419 are precision, CMOS, monolithic analog switches offering low on‑resistance, low charge injection, and high ESD tolerance. They are available in SPST (DG417/DG418) and SPDT (DG419) configurations and support both single‑supply (+10V to +30V) and bipolar (±4.5V to ±20V) operation.
Key specifications include on‑resistance matching of up to 3 Ω, flatness of up to 4 Ω, switching times under 175 ns (turn‑on) and 145 ns (turn‑off), off‑leakage below 5 nA at +85 °C, and an ESD rating of at least 2000 V. The devices are suited for sample‑and‑hold circuits, communication systems, test equipment, and many other applications.
| On‑resistance matching | 3 Ω max |
|---|---|
| ESD tolerance | 2000 V minimum |
| Off‑leakage current | <5 nA at +85 °C |
| Supply voltage range | +10 V to +30 V single‑supply or ±4.5 V to ±20 V bipolar |
| Drain‑Source on‑resistance (RDS(ON)) | 35 Ω max |
The devices have an ESD tolerance of at least 2000 V per Method 3015.7.
They operate from a single +10 V to +30 V supply or from bipolar ±4.5 V to ±20 V supplies.
The off‑leakage current is less than 5 nA at +85 °C.
