ADM206AN - 4/3 RS-232 200 kbps Transceiver | Analog Devices
MPN： ADM206AN ✓ 啟用中ADM206AN 概覽
An RS-232 transceiver is an interface IC that converts logic-level digital signals into RS-232-compatible line levels and converts received line levels back into logic-level signals. The ADM206 family belongs to the broader line-driver/receiver and interface-IC hierarchy, where EIA-232-E and V.28 links connect embedded systems, computers, industrial controllers, and communications equipment. Its single +5 V supply and integrated charge-pump support simplify systems that require RS-232 functionality without external negative-voltage generation.
The ADM206 provides four transmit channels and three receive channels. The receiver design is intended for dependable operation across RS-232 signal levels, while the driver outputs use the device's CMOS charge-pump approach to produce the required bipolar line voltage. The device also includes shutdown control and an enable function, allowing power management or interface isolation in multi-channel systems. Its 200 kbps capability is suitable for moderate-speed serial links rather than high-speed differential interconnects.
The ADM206AN is the through-hole PDIP-24 ordering variant. The provided manufacturer and distributor data identify a 24-pin PDIP package, while a surface-mount ADM206ARZ variant is a different package and is not a drop-in replacement for a PDIP footprint. Engineers should therefore preserve the package outline and verify the exact pin functions in the manufacturer datasheet before substitution.
Typical uses include RS-232 ports in embedded control equipment, test systems, industrial instrumentation, computer peripherals, and service interfaces. For new designs, the shutdown and enable pins can support power sequencing or reduce consumption when the interface is idle. The principal trade-off is that a +5 V RS-232 solution still uses external charge-pump capacitors and occupies a relatively large through-hole package compared with newer compact interface transceivers.
Use the manufacturer's ADM206 datasheet and product page to confirm pinout, capacitor values, receiver thresholds, timing, and absolute maximum ratings. Do not infer values from a distributor listing alone. This page distinguishes verified product identity and application context from electrical parameters that require confirmation in the full datasheet.

典型應用
ADM206AN 適用於 6 應用s: Embedded RS-232 Control Interfaces, Computer Peripherals and Service Ports, Test and Measurement Equipment, Industrial Instrumentation and Data Acquisition, Legacy Communication Upgrade, Low-Voltage Serial Communication Platforms.
Embedded RS-232 Control Interfaces
The ADM206AN fits embedded controllers, service ports, and industrial control equipment that need RS-232 communication from a +5 V supply. Its four drivers and three receivers provide flexible channel allocation for commands, status, and acknowledgments, while the 200 kbps rate covers moderate-speed control traffic. The device avoids a separate ±12 V supply, but its 24-pin PDIP footprint and 0.1 µF charge-pump capacitors should be planned into the board layout. Verify enable and shutdown polarity in the manufacturer datasheet before assigning them to a power-sequencing scheme.
推薦
Computer Peripherals and Service Ports
The ADM206AN is appropriate for legacy-compatible service and configuration ports where a host or peripheral requires multiple RS-232 channels. A +5 V system can use the transceiver without generating external ±12 V rails, and the four-driver configuration can support several outbound control or status lines. The 200 kbps signaling rate is sufficient for many serial configuration protocols, but cable length, termination, grounding, and driver loading remain system-level constraints. The through-hole PDIP-24 package is particularly useful for industrial boards and legacy chassis.
推薦
Test and Measurement Equipment
The ADM206AN can be used in test systems that need to distribute commands and collect responses through RS-232 links. Four drivers may control instruments or fixtures, while three receivers can collect status data, making the channel asymmetry useful in automated test architectures. Its +5 V operation simplifies instrumentation that already has a low-voltage control rail, and the 200 kbps rate is adequate for many short-distance serial control protocols. Designers should still verify receiver thresholds, timing, and isolation requirements against the full Analog Devices datasheet.
推薦
Industrial Instrumentation and Data Acquisition
The ADM206AN is relevant to instrumentation that exposes a +5 V controller to external RS-232 equipment, especially where multiple command and monitor channels are needed. The EIA-232-E and V.28 positioning supports conventional serial-device integration, while the integrated charge-pump arrangement avoids a separate negative supply. In field equipment, cable transients, grounding, and EMI can be more important than headline data rate, so protection and isolation may be required around the interface. The provided data does not establish an industrial temperature range, so qualification must be checked.
推薦
Legacy Communication Upgrade
The ADM206AN can be considered for legacy RS-232 board upgrades because the verified material describes the ADM2xx family as intended for systems where ±12 V is not available and as a plug-in upgrade for MAX205-211/213. This makes it useful when maintaining older communications architecture while standardizing on a +5 V supply and CMOS interface implementation. However, the statement does not prove that every MAX suffix is pin-compatible. A replacement should be accepted only after comparing package, pinout, control-pin levels, and timing.
推薦
Low-Voltage Serial Communication Platforms
The ADM206AN suits platforms that already operate from +5 V and need an RS-232 port rather than a modern differential bus. The four-driver, three-receiver organization allows asymmetric command and response wiring, while the 200 kbps rate supports moderate-speed serial links. Compared with designs requiring external negative-voltage generation, the integrated charge-pump approach reduces supply complexity but retains the need for carefully placed capacitors. Board planners should reserve space for the PDIP-24 footprint and provide adequate RS-232 connector protection where cables leave the enclosure.

主要差異化特點
- Single +5 V RS-232 interface with integrated charge-pump support (對比MAX211IDB)
- Asymmetric four-driver, three-receiver channel allocation (對比ADM238LJN)
- Higher verified signaling rate than the related ADM238LJN (對比ADM238LJN)
- Through-hole PDIP-24 mechanical fit for legacy-style boards (對比ADM206ARZ)
設計說明
Place the three 0.1 µF charge-pump capacitors and the required supply-bypass components exactly as recommended in the current Analog Devices datasheet. Keep the charge-pump traces short and continuous, minimize loop area, and route noisy driver-current paths away from receiver inputs. The PDIP-24 footprint provides generous through-hole spacing, but connector-side protection and ground-return routing still determine real-world EMI performance.
The verified feature summary lists 15 mW low-power operation, but final power budgeting should use the datasheet's actual supply current, enabled-channel state, and shutdown behavior. Do not assume that all four drivers are continuously active at maximum loading. Confirm the +5 V source tolerance and provide local decoupling near the device, especially when external cable capacitance and multiple drivers create transient demand.
ADM206AN is a 24-pin PDIP part, while ADM206ARZ is identified in the comparison data as a surface-mount SOIC-24 variant. Do not substitute the ARZ suffix on an existing PDIP board without a footprint redesign. Also verify the ADM206ANZ and related suffix pin functions because the supplied search results identify family-related listings but do not independently document every suffix's complete electrical limits.
For RS-232 cables, treat the connector side as an electrically harsh environment even when the logic side operates from +5 V. Use the receiver and driver channels according to the datasheet, maintain a suitable ground reference, and consider external surge or ESD protection where cables leave the board. The 200 kbps headline rate does not remove the need to control cable length, loading, reflections, and grounding.
