This document is the introduction manual of MAX4584/MAX4585 series products, which introduces the features and characteristics of the products, including single switch, double switch, switch resistance, signal isolation, serial interface, etc.
The MAX4584 and MAX4585 are serial‑interface programmable switches designed for multimedia applications. Each device contains one normally‑open SPST switch and one SPDT switch that can be controlled via a 2‑wire I²C‑compatible interface (MAX4584) or a 3‑wire SPI/QSPI/MICROWIRE interface (MAX4585). Typical uses include cellular phones, set‑top boxes, video conferencing equipment, and high‑end audio systems.
Key specifications include a supply voltage range of 2.7 V to 5.5 V, on‑resistance up to 65 Ω, audio off‑isolation of –83 dB at 20 kHz, video off‑isolation of –48 dB at 10 MHz, and operation over –40 °C to +85 °C. The datasheet provides detailed electrical characteristics, timing diagrams for both interfaces, and pin‑out information for the 10‑pin µMAX package.
| Supply Voltage Range | 2.7 V to 5.5 V |
|---|---|
| On‑Resistance (RON) Max | 65 Ω |
| Audio Off‑Isolation (20 kHz) | -83 dB |
| Video Off‑Isolation (10 MHz) | -48 dB |
| Operating Temperature Range | -40 °C to +85 °C |
| Package | 10‑pin µMAX |
The devices operate from a single supply voltage of 2.7 V to 5.5 V.
Audio off‑isolation is –83 dB at 20 kHz.
Only two I/O lines (SCL and SDA) are needed for the 2‑wire I²C‑compatible interface.
The MAX4585 uses a 3‑wire SPI/QSPI/MICROWIRE‑compatible serial interface.
