The MAX1482CPD+ is an integrated circuit (IC) component that provides a robust interface between a low-voltage microcontroller and a high-voltage RS-485 network. It is designed to transmit and receive data over long distances in noisy industrial environments. Here, we will provide an overview of MAX1482CPD+ as well as its key features.
The MAX1482CPD+ supports a wide supply voltage range from 4.5V to 5.5V, making it suitable for various microcontroller systems. It can handle data rates up to 2.5Mbps, allowing for high-speed communication. The IC features a low-power shutdown mode, which reduces power consumption during idle periods and increases overall efficiency.
One of the notable features of MAX1482CPD+ is its robustness in industrial environments. It incorporates a slew-rate-limited driver and receiver to minimize electromagnetic interference (EMI) and reflections on the network. Additionally, the IC has integrated protection against voltage spikes up to ±35V, protecting the internal circuitry from potential damage.
The IC supports full-duplex communication, enabling simultaneous transmission and reception of data. It features a differential driver output, providing improved noise immunity and common-mode rejection. Furthermore, it has a receiver input threshold that allows reliable operation in noisy environments.
MAX1482CPD+ employs a fail-safe receiver, which ensures that the receiver output voltage will be in a defined state if the bus is idle or disconnected
