The MAX490CPA is an integrated circuit component manufactured by Maxim Integrated. It is a quad, high-speed, low-power, RS-485/RS-422 transceiver. The chip is well suited for use in applications requiring long-distance communication and robustness in noisy environments.
The MAX490CPA features four independent transceivers, each capable of converting logic level signals into balanced differential signals suitable for long-range transmission. The transmitters utilize slew-rate-limited drivers that reduce electromagnetic emissions and enhance signal integrity.
One of the key features of the MAX490CPA is its high data rate capability. It supports data rates of up to 2.5 Mbps, making it suitable for various high-speed communication protocols. This feature makes it an ideal choice for applications requiring fast data transfer, such as industrial automation, automotive systems, and telecommunication equipment.
Another notable feature of the MAX490CPA is its ±15kV ESD (electrostatic discharge) protection on the RS-485/RS-422 bus pins. This robust protection safeguard against electrostatic discharge events, ensuring reliable operation in demanding environments.
The transceiver offers a wide supply voltage range, from +4.5V to +5.5V, providing flexibility in various power supply configurations. It also features a low power consumption design, which aids in reducing overall power consumption in battery-powered devices, extending the operational life
