ADM3061E
Overview
The ADM3061E is a half-duplex RS-485 transceiver from Analog Devices. It implements one driver and one receiver and supports data rates up to 500 kbps while operating from 3.0 V to 5.5 V. The device is offered in 8-pin TSSOP and 8-pin MSOP packages and is specified for operation from -40 C to 85 C.
Why Choose This Part
Wide supply range (3.0 V to 5.5 V) makes the ADM3061E compatible with both 3.3 V and 5 V logic systems. Small 8-pin surface-mount packages save PCB space, and the -40 C to 85 C rating suits many embedded and industrial environments. The 500 kbps data rate is adequate for common RS-485 applications such as Modbus and remote I/O.
Applications
Key Specifications
Getting Started
The ADM3061E is a passive transceiver device; no IDE is required. Interface it to a microcontroller UART and provide direction control for transmit/receive as required by your system. Follow standard RS-485 practices: place 120 ohm termination resistors at the ends of the bus, add biasing resistors to establish a defined idle state, and verify the device supply voltage and grounding. Consider board-level ESD protection and common-mode isolation as appropriate for your environment.
