The AD7590, AD7591 and AD7592 families are latch‑proof, dielectrically isolated CMOS analog switches with on‑chip data latches and over‑voltage protection up to +25 V. Each device contains two independent SPDT switches and is pin‑compatible with the AD7510 series.
The document lists electrical specifications (on‑resistance, leakage, switching times), absolute maximum ratings, ordering options for plastic DIP and Cerdip packages, and mechanical outline dimensions for 14‑pin and 16‑pin configurations.
| Overvoltage Protection | +25 V |
|---|---|
| On‑Resistance (Ron) | 60 nΩ typ |
| Leakage Current (OFF state, AD7590DI) | 0.5 nA typ |
The devices are protected against voltages up to +25 V above the supply voltage.
Each AD7590DI contains two independent SPDT switches packaged in a 14‑pin DIP.
The typical off‑state leakage current is 0.5 nA.
