This is a RS-232 serial port driver/receiver produced by Analog Devices. It features ultra-low power consumption and high compatibility. It operates with a voltage range of 3V to 3.6V and is suitable for notebooks, peripherals, modems, printers and other devices.
The ADM560 and ADM561 are ultra‑low‑power RS‑232 driver/receiver ICs that operate from a single +3.3 V supply. They include an on‑chip charge‑pump voltage converter that generates ±6.6 V, allowing operation with 3 V or 5 V logic levels while consuming only a few microwatts.
The document provides detailed specifications, absolute maximum ratings, pin configurations, functional block diagrams, and typical performance curves, along with enable and shutdown control information for both devices.
| Output Voltage Swing (typical) | +5.0 V to +5.5 V |
|---|---|
| Power Supply Current (no load) | 5 mA |
| Shutdown Supply Current | 0.2 pA |
| EIA‑232 Input Voltage Range | -25 V to +25 V |
| Maximum Input Voltage (over‑voltage protection) | +25 V |
| Package Types | 28‑lead SOIC and 28‑lead SSOP |
The shutdown supply current is specified as 0.2 pA when SHDN is grounded.
Two receivers stay active in shutdown mode for the ADM560, allowing peripheral monitoring.
The SSOP package dissipates up to 900 mW.
