Factories are expanding to enable Industry 4.0, buildings are getting smarter, and robotics are continually evolving. Such widespread innovation drives designers in various industries to optimize and enhance their products. Our industrial digital and analog input/output (I/O) IC portfolio provide the highest levels of robustness on the market with the highest integration and software configurability for a more flexible solution. High voltage industrial digital input (DI) and digital output (DO) signals (also called binary signals), typically range in magnitude from 0 V to 24 V. Digital I/O signals are used by industrial automation and control equipment, operating in harsh and noisy environments, to communicate on/off status between remote devices and controllers. Our industrial digital I/O ICs perform voltage level translation while providing circuit protection. Many also perform data serialization to allow economical operation through digital signal isolators. Analog I/O signals are used in both factory and build automation to enable smarter sensing and push intelligence at the edge. Our best-in-class analog input (AI), analog output (AO), and configurable analog input/output (CIO) ICs provide the highest levels of system accuracy in the market with per-channel software configurability. Factory calibration and robust integrated protection reduce overall system cost and size. Innovative designs decrease power consumption allowing operation of more channels without derating for ambient temperature. Key benefits: most robust solutions on the market with the highest integration; software configurability provides flexibility and reduces end product SKUs; and fast time to market with the best support in the industry.

The IO-Link® interface simplifies communication to smart sensors and actuators, combining signaling with power-over-cable technology. It has become one of the key devices as industrial automation systems are growing more interconnected and intelligent to accommodate demands for centralized control and optimized production. Analog Devices implements both device PHY and master PHY interfaces (COM1/COM2/COM3). Designing with harsh industrial environments in mind, the master 4-port IO-Link power and communications interface, as well as the IO-Link transceivers featuring Integrated Step-Down Regulators and LDO with ±60V cable interface protection provide the required ruggedness. Optimum EMC performance is achieved with adjustable current limit and slew rate transmitters. Automatic wake-up request (WURQ) generation and an output supply current boosting capability for device startup are also available. Additional components integrate a 300 mA step-down (buck) regulator and a 150 mA LDO to supply all the power required for internal electronics in an connected sensor or actuator.

LVDS (Low voltage differential signaling) is a standard for communicating at high speed in point-to-point applications and M-LVDS (Multipoint LVDS) is a similar standard for multi-point applications. Both LVDS and M-LVDS offer a long-distance digital interface for serial communication over an electrical interconnect.

Analog Device's LVDS portfolio includes isolated LVDS and non-isolated LVDS & M-LVDS transmitters/line drivers and receivers. With 8 kV IEC ESD performance standards for robust, inter-board applications in harsh electrostatic environments, our LVDS modules conform to the TIA/EIA-644 LVDS standard with data rates up to 600Mbps. The M-LVDS products are ideal for applications where designers need to transmit at data rates up to 100 Mbps or 250 Mbps to multiple nodes. M-LVDS allows a single pair of differential lines to carry this high speed information, saving on connector size and reducing the number of lanes required to fan out this information. Integration of Analog Devices' iCoupler® technology allows for high speed operation that also provides drop-in galvanic isolation of LVDS signal chains. Isolated LVDS with data rates of up to 2.5 Gbps with very low jitter opens up new applications in Instrumentation and Digital Health.

Analog Devices’ RS-232/RS-485 multiprotocol transceivers are the only parts in the market that allow protocol switching and allow for switching between half-/full-duplex operation and switching on/off termination resistors, both of which minimize physical user intervention when reconfiguring networks. Features include 3.3 V to 5 V operation, up to ±26 kV ESD, a logic supply pin, and small LFCSP packages. As large-scale computing applications typically require more protocols than the RS-232 and RS-485 protocols found in everyday applications, we support legacy protocols. These include V.28 (RS-232), V.35, RS-449, RS-530, RS-530-A, V.36, or X.21. Software-selectable protocol, cable termination, and data terminal equipment (DTE) or data communications equipment (DCE) configurations all provide convenient flexibility.
