ADM207AR - 5/3 RS-232 Transceiver, 200 kb/s | Analog Devices
MPN: ADM207AR ✓ Hoạt độngADM207AR Tóm tắt
An RS-232 transceiver is an interface IC that combines line drivers, receivers, and charge-pump voltage-boost circuitry. It translates logic-level UART signals between a host and a noisy, differential-distance serial link. The ADM207AR belongs to the RS-232 transceiver class within interface ICs and supports the asymmetric voltage levels required by legacy serial communications.
The verified feature data identifies five transmitters, three receivers, a +5 V supply, 0.1 µF capacitors, 120 kb/s in one secondary source and 200 kb/s in the Analog Devices product listing. It also reports a 9 V output swing from a +5 V supply, 15 mW low power, low-power shutdown, 30 V receiver input levels, latch-up protection, and plug-in compatibility with MAX205 through MAX213. Exact operating limits not present in the supplied data are marked for verification rather than guessed.
The charge-pump topology generates the bipolar voltage needed by RS-232 drivers from a single +5 V rail. This reduces system power-supply complexity, but external capacitor selection, layout, and signal-return continuity remain critical. Five driver channels permit multi-drop or multi-port RS-232 links, while three receiver channels provide simultaneous receive monitoring or handshake support.
Typical applications include industrial control equipment, data acquisition systems, instrumentation, barcode or serial adapters, legacy peripheral ports, and embedded controller links. The device is appropriate when the system already uses RS-232 logic levels and must interoperate with existing equipment rather than modern differential buses such as RS-485.
For a new PCB, verify the complete 24-pin pinout, capacitor values, driver and receiver loading, and maximum cable length against the current manufacturer datasheet. Keep charge-pump traces short, place capacitors close to their associated pins, and provide a continuous ground return between communicating systems.
This page combines the supplied manufacturer and distributor findings with practical interface-selection guidance. It explicitly separates verified facts from unavailable parameters, so procurement and design decisions can be checked against the authoritative ADM207 datasheet before release to production.

Ứng dụng tiêu biểu
ADM207AR phù hợp cho 7 Áp dụngs: Industrial serial control, Data acquisition instrumentation, Barcode and serial adapters, Legacy peripheral ports, Instrumentation and test equipment, Embedded serial interface bridge, Network equipment management port.
Industrial serial control
The ADM207AR fits legacy industrial controllers that must expose several RS-232 channels from a single +5 V supply. Its five drivers and three receivers provide more channel flexibility than a basic one-driver, one-receiver transceiver, while the manufacturer-stated 200 kb/s rate covers common UART traffic. Place the device near the connector and place its 0.1 µF charge-pump capacitors close to the associated pins. The principal trade-off is that RS-232 remains a single-ended interface, so ground continuity and cable length limit reliable communication more strongly than the nominal baud rate alone.
Được đề xuất
Data acquisition instrumentation
The ADM207AR is useful in legacy data-acquisition equipment where a controller must connect several measurement or control peripherals through RS-232. The five-driver configuration supports multiple outbound command paths, while three receivers can handle return data and status signals. A single +5 V rail eliminates the need for a separate ±12 V supply, and 0.1 µF charge-pump capacitors match the verified design requirements. Engineers should still budget for cable-side ESD protection because the verified 30 V receiver input capability is not a substitute for a complete external surge-protection network.
Được đề xuất
Barcode and serial adapters
The ADM207AR can support compact barcode-reader, scanner, and legacy peripheral adapters that need more than one RS-232 path without multiple single-channel transceivers. Its 200 kb/s manufacturer rating is suitable for ordinary serial adapter traffic, and the five transmitters allow a host to control several peripherals from one PCB. Keep the 24-pin SOIC close to the output connectors and route charge-pump current loops away from connector return paths. Validate read range, cable capacitance, and hot-plug behavior because those system parameters are not specified by the supplied source snippets.
Được đề xuất
Legacy peripheral ports
The ADM207AR is appropriate when maintaining compatibility with older peripherals that expose multiple RS-232 control and status lines. The three receivers permit simultaneous monitoring of acknowledgment, ready, or fault signals, while five drivers support command and data outputs. Its +5 V operation simplifies retrofit boards that already regulate 5 V, but the interface still needs correct logic thresholds, termination practices, and a defined cable return. Use the current Analog Devices datasheet to verify absolute maximum ratings and receiver thresholds before connecting long or industrial cables.
Được đề xuất
Instrumentation and test equipment
The ADM207AR can serve as the host interface in instrumentation that must communicate with older RS-232 analyzers, printers, controllers, or calibration equipment. Three receive channels are useful for bidirectional control, and the manufacturer-stated 200 kb/s rate supports high-speed legacy serial links. Place the transceiver near the rear-panel connector and provide a low-impedance return path. For laboratory instruments, add appropriately selected transient protection because the supplied material does not define a complete EMC, surge, or IEC test strategy.
Được đề xuất
Embedded serial interface bridge
The ADM207AR can bridge a modern controller UART to a legacy RS-232 subsystem while preserving several control paths. A microcontroller or module can drive the five command channels and receive status on three channels, reducing the need for separate transceivers. The single +5 V architecture simplifies power design, but software must control RS-232 direction, framing, and timing correctly. Do not treat the transceiver as an RS-485 interface: its single-ended signaling and charge-pump outputs are intended for EIA-232-E and V.28 links.
Được đề xuất
Network equipment management port
The ADM207AR is suitable for a management interface on legacy network or communications equipment where RS-232 remains required for configuration and diagnostics. Multiple drivers and receivers can separate console, control, and status wiring, while the +5 V supply matches many embedded platforms. Keep the cable interface physically separated from high-speed Ethernet or switching circuitry, and provide chassis or board grounding appropriate to the installation. The verified 30 V receiver input-level figure should still be evaluated alongside the selected surge and ESD protection.

Ghi chú thiết kế
Place the verified 0.1 µF charge-pump capacitors close to the ADM207AR pins specified by the datasheet. Keep the high-current charge-pump loops compact, minimize loop area, and route them away from UART receivers and sensitive analog inputs. The supplied information does not include the complete pinout or exact capacitor pin numbers, so use the current Analog Devices schematic rather than inferring connections from package position.
RS-232 is single-ended, so a reliable ground reference is part of the communication path. Provide a low-impedance return between connected systems and keep the cable ground conductor appropriately terminated. Avoid relying only on the reported 30 V receiver input-level capability for industrial surge protection; add cable-side protection selected for the installation and verify it against the interface voltage and ground-referenced equipment requirements.
Do not treat any 24-pin RS-232 IC as an automatic drop-in replacement. Confirm the exact driver and receiver counts, logic levels, charge-pump capacitor requirements, shutdown polarity, exposed connections, absolute maximum ratings, and package pin sequence. The supplied ADM207 data calls it a plug-in upgrade for MAX205 through MAX213, but individual suffix variants still require datasheet-level verification before substitution.
Thông tin tuân thủ
The supplied verified data does not state part-level RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance for ADM207AR. Values remain unknown rather than inferred.
