ADG709BRUZ-REEL7 - 4:1 Differential MUX | Analog Devices

The ADG709BRUZ-REEL7 is a low voltage, CMOS analog multiplexer from Analog Devices, comprising four differential channels. It switches one of four differential inputs to a common differential output, controlled by a 2-bit binary address (A0, A1) and an enable (EN) input. When disabled, all channels are switched OFF. The device operates over a supply range of 1.8 V to 5.5 V, with a low on-resistance of 4.5 ohm, making it suitable for precision analog signal routing in battery-powered and low-voltage systems. An analog multiplexer is a device that selects one of several analog input signals and forwards it to a single output. In this case, the ADG709 is a differential 4:1 multiplexer, meaning it handles four differential signal pairs and routes one pair to the output. This is essential in applications where signal integrity and minimal distortion are critical, such as data acquisition systems, communication systems, and audio/video switching. The multiplexer acts as a switch, connecting the selected input to the output while providing high isolation from unselected channels. Key features of the ADG709BRUZ-REEL7 include bidirectional analog channels, glitch-free switching, and a wide operating temperature range of -40°C to +125°C. The low on-resistance of 4.5 ohm ensures minimal signal attenuation, while the CMOS construction provides low power consumption. The device is available in a 16-lead TSSOP package, which is compact and suitable for space-constrained designs. The EN pin allows for easy power-down or channel disabling, enhancing system flexibility. Technically, the ADG709 uses a CMOS process that provides low leakage currents and high switching speeds. The differential architecture improves noise immunity by rejecting common-mode noise, which is critical in industrial and communication environments. The device also features break-before-make switching, preventing momentary shorting of channels during transitions. This ensures glitch-free operation, which is vital in precision measurement and audio applications. Typical applications include data acquisition systems, communication systems, relay replacement, audio and video switching, and battery-powered systems. In data acquisition, the ADG709 can route multiple sensor signals to a single ADC, reducing component count and cost. In audio systems, it enables seamless switching between multiple audio sources without audible clicks or pops. When designing with the ADG709, ensure that the analog input signals remain within the supply rails to avoid forward-biasing the internal diodes. Additionally, proper decoupling of the power supply pins with 0.1 uF capacitors is recommended to minimize noise. The EN pin can be used to place the device in a low-power state when not in use, conserving battery life in portable applications.

ADG709CRUZ - 3Ω Low Voltage 4-Ch Differential MUX | Analog Devices

The Analog Devices ADG709CRUZ is a low-voltage, CMOS analog multiplexer comprising four differential channels, switching one of four differential inputs to a common differential output as set by 2-bit binary address lines A0 and A1. Housed in a 16-pin TSSOP (RU-16) package, the device provides 3 Ω typical on-resistance, 0.75 Ω on-resistance flatness, and 14 ns tON/tOFF switching times. The C grade specifies tighter leakage performance for precision signal-chain applications. Operating from 1.8 V to 5.5 V single supply or ±2.5 V dual supply, the ADG709CRUZ is TTL-/CMOS-compatible and qualified for automotive environments per the ADG709 datasheet family. A CMOS analog multiplexer is a precision switching element that routes one of several analog signals to a common output under digital control, forming the analog front end of data acquisition, instrumentation, and signal-routing systems. Multiplexers such as the ADG709 sit hierarchically between simple analog switches (single SPST functions) and larger crosspoint/fanout switches. They are fundamental building blocks inside data acquisition systems (DAQ), communication transceivers, audio/video routing, battery-powered sensor conditioning, and any design that needs to time-share a single high-performance ADC across multiple analog sources. Key features of the ADG709CRUZ include 100 pA typical leakage at 25 °C, break-before-make switching to eliminate momentary shorting between channels, low power consumption (typically < 1 µW), an active-high EN pin for disabling all channels simultaneously, and TTL-/CMOS-compatible digital inputs across the full supply range. The wide supply tolerance lets a single board design serve 3.3 V and 5 V rails without hardware changes. The device uses a charge-pump-friendly CMOS switch architecture with N-channel FET pass transistors controlled by on-chip level shifters. This yields low on-resistance that remains flat across the analog input range, minimizing total harmonic distortion (THD) when routing audio signals or wide-swing sensor outputs. Typical applications include data acquisition front-ends (multiplexing thermocouples, RTDs, or strain gauges to a single ADC), audio/video signal routing, communication systems, battery-powered portable instruments, relay-replacement circuits in industrial controls, and automotive sensor multiplexing. Designers should keep input signals within the supply rails and add small guard traces to maintain flat RON performance at high frequencies. When laying out the PCB, place decoupling capacitors (100 nF plus 10 µF bulk) as close as possible to VDD and GND. Avoid routing digital address lines near analog traces to prevent capacitive coupling into the signal path.

An analog switch is an integrated semiconductor device that connects or disconnects signal paths under digital control. The ADG714 belongs to the CMOS analog-switch and interface-IC hierarchy, where matched low on-resistance and bidirectional conduction help preserve signal integrity in measurement, instrumentation, and communication equipment. Its serial control reduces the number of dedicated logic pins compared with an individually controlled switch array. The ADG714 family provides complementary CMOS octal SPST switching, closely matched on-resistance across channels, and flat on-resistance over the full signal range. The verified source data identifies a 32 ns turn-on time, 18 ns turn-off time, a -2.5 V to 2.75 V supply specification, and operation from -40 °C to 85 °C. The 24-TSSOP package is surface mount and supports compact PCB layouts. The three-wire serial interface uses shift-register data loaded into the device, allowing multiple switch states to be configured with a compact command structure. This interface is useful when the system already has a serial bus and needs repeatable routing of analog signals. Exact serial timing, logic levels, channel mapping, and electrical limits should be confirmed in the manufacturer datasheet. Typical uses include signal multiplexing in automated test equipment, instrumentation signal routing, communication-channel selection, data-acquisition systems, and low-voltage analog front ends. Designers should account for supply voltage, signal range, on-resistance, switching time, logic compatibility, and unused-channel handling during layout and firmware design. A critical layout practice is to keep analog signal traces short and route control signals away from sensitive paths. Confirm the manufacturer’s recommended decoupling and exposed-pin requirements before finalizing the PCB.

It is built on a submicron CMOS process that delivers high switching speed (tON 20 ns typical, tOFF 7 ns typical) with extremely low power dissipation and -3 dB bandwidths greater than 200 MHz. An analog switch (also called a CMOS switch or analog multiplexer) is a solid-state device that uses MOSFET transistors to route analog or digital signals between multiple nodes without mechanical parts. Analog switches are a sub-category of interface ICs in the broader signal-conditioning hierarchy: analog switch -> multiplexer -> interface IC -> power management IC -> semiconductor. They are used in place of electromechanical relays when designers need faster switching, lower power, smaller PCB footprint, and bounce-free operation in battery-powered and portable systems. Key features of the ADG779BKSZ-REEL include a wide 1.8 V to 5.5 V single-supply range, 2.5 Ω typical on-resistance with 0.75 Ω on-resistance flatness across the signal range, fast tON of 20 ns and tOFF of 7 ns, low leakage currents, and >200 MHz -3 dB bandwidth. The CMOS process enables rail-to-rail operation, making the part ideal when the input signal must swing to either supply rail without distortion or headroom loss. The part ships on 7-inch tape-and-reel as the -REEL suffix variant. Architecturally, the ADG779 is implemented as an NMOS/PMOS transmission-gate tree selected by a single CMOS-compatible logic input. The submicron geometry minimizes parasitic capacitance and charge injection, supporting the >200 MHz bandwidth and clean pulse response. Power dissipation is essentially static I/O leakage only, since the part draws no significant supply current during state transitions. Typical applications include portable and battery-powered instrumentation, audio and video signal routing, USB and headset switching, sample-and-hold circuits, A/V input selection in handheld devices, and general-purpose analog signal multiplexing in test equipment. Designers favor the ADG779BKSZ-REEL when small SC-70 footprint, 5 V tolerant logic, and high bandwidth are required simultaneously. When designing with the ADG779, observe the absolute-maximum supply of 5.5 V and avoid signals that exceed the rails. Decouple VDD with a 0.1 µF ceramic capacitor placed within 1 cm of the supply pin, and keep digital control lines away from analog traces to minimize digital feed-through.

It operates from a single 1.8 V to 5.5 V supply, supports rail-to-rail signal swing, and provides TTL-/CMOS-compatible logic inputs. The device is qualified for the -40°C to +125°C automotive temperature range and carries up to 400 mA of continuous current. An analog switch, also called a SPST (Single-Pole Single-Throw) switch, is a solid-state semiconductor device that uses MOSFET transistors to connect or disconnect an analog signal path under digital control. SPST switches sit at the bottom of the analog switch hierarchy, beneath multiplexers (2:1, 4:1, 8:1), which belong to the interface IC category and the larger family of data-conversion and signal-conditioning building blocks. ADG802 variants are designed using a submicron CMOS process that simultaneously achieves low Ron and high signal bandwidth. Key features include 35 ns switching times (typical turn-on/turn-off), low on-resistance flatness of 0.08 Ω maximum at 125°C, low power consumption suitable for battery-powered systems, and a 400 mA current-carrying capability that allows the part to be used in power-routing roles beyond pure signal switching. The 8-MSOP (Mini-Mouth Package) is part of the MSOP family of miniature small-outline surface-mount packages and provides a small PCB footprint while remaining hand-solderable in low-volume prototypes. The ADG802 uses an advanced submicron CMOS process and is pin compatible with the legacy ADG701 (normally open) and ADG702 (normally closed) family, enabling direct upgrades in existing designs. The very low on resistance (typically 0.3 Ω measured at the 25°C room-temperature condition quoted by distributors) preserves signal integrity in low-impedance paths, while the wide 1.8 V to 5.5 V supply range covers modern 1.8 V, 2.5 V, 3.3 V, and 5 V digital systems. Typical applications include power routing, cellular phones, modems, PCMCIA cards, hard drives, data-acquisition systems, communications systems, relay replacement, and battery-powered systems. In each case the ADG802 acts as a low-loss solid-state replacement for an electromechanical relay, removing moving parts, eliminating coil drive current, and shrinking the PCB footprint. When designing with this device, place a 0.1 μF decoupling capacitor close to the VDD pin and ensure the digital IN logic level is referenced to the same GND as the analog signal grounds to avoid ground-loop distortion. Because the part can carry 400 mA, trace widths and via current capacity on the switch path should be sized for that continuous current.

The Analog Devices ADM1485ARZ is a 5 V, high-speed (30 Mbps), low-power, half-duplex differential line transceiver that complies with both EIA RS-485 and EIA RS-422 standards. Housed in an 8-pin SOIC_N package, it integrates one driver and one receiver (1/1) on a single die, making it suitable for bidirectional data communication on multipoint bus transmission lines. What is an RS-485/RS-422 transceiver? It is a physical-layer interface IC that converts a single-ended TTL/CMOS logic signal from a UART, MCU, or FPGA into a differential signal suitable for transmission over twisted-pair cable, and vice versa. RS-485 supports multipoint, half-duplex or full-duplex buses with up to 32 unit loads and common-mode voltages up to ±12 V, while RS-422 is its point-to-point/point-to-multipoint predecessor with similar differential signaling. Transceivers sit at the bottom of the OSI physical layer, bridging digital logic to industrial bus standards such as Profibus, Modbus, DMX512, and BACnet. Key specifications include a maximum data rate of 30 Mbps (with low driver skew for minimal EMI), a single 5 V supply (4.75 V to 5.25 V), ±12 V bus common-mode range, 70 mV receiver hysteresis, BiCMOS construction for low power, and on-chip thermal shutdown plus short-circuit protection. The differential driver outputs are well balanced to ensure distortion-free transmission, and minimal propagation delay supports high-speed industrial links without timing margin loss. Architecturally, the ADM1485ARZ uses BiCMOS process technology that combines the low power consumption of CMOS with the high drive capability of bipolar transistors. The result is a robust transceiver that draws minimal quiescent current while still swinging RS-485 levels into 60 ohm loads (two 120 ohm terminations in parallel). Internal fail-safe biasing on the receiver inputs guarantees a defined logic-high output when the bus is idle or open. Typical applications include industrial fieldbus networks (Profibus, Modbus), building automation (BACnet, DMX512 lighting), point-of-sale and banking terminals, motor drive feedback links, and any half-duplex multidrop RS-485 wiring run. The wide common-mode range makes the part tolerant of ground-potential differences between nodes in factory environments. When designing with the ADM1485ARZ, place the IC close to the bus connector and use a 100 ohm differential termination at each end of the cable. For multi-node buses, fail-safe biasing resistors (typically a pull-up on B and pull-down on A) may be needed if the part is operated without termination. The half-duplex design requires firmware control of the DE and RE pins, which can be tied together when only one direction is active at a time.

It supports data rates up to 230 kbit/s and uses charge-pump capacitors as small as 0.1 µF to generate approximately ±10 V RS-232 output levels. An RS-232 transceiver is an interface IC that converts logic-level signals from a controller or terminal into bipolar RS-232 voltages and converts received RS-232 levels back into CMOS-compatible logic. Within the signal-chain hierarchy, the ADM202EAN belongs to the RS-232 interface transceiver category and connects UART-based digital systems to unipolar, single-ended communications ports using differential bipolar signaling. Key features include compliance with the TIA/EIA-232-E and V.28 specifications, 230 kbit/s operation, and electromagnetic-immunity provisions covering the EU 89/336/EEC EMC Directive. ESD protection is specified at 8 kV contact discharge, 15 kV air-gap discharge, and 15 kV human-body-model levels. Fast transient burst immunity is referenced to IEC 61000-4-4, while low EMI emissions are referenced to EN 55022. The ADM202E family provides a pin-compatible upgrade path for existing ADM202, ADM232L, MAX202E, and MAX232E sockets. Its charge-pump architecture eliminates the need for a separate external 5 V-to-±10 V converter, reducing board area and component count. The 230 kbit/s capability is appropriate for industrial equipment, data-acquisition systems, point-of-sale terminals, and legacy serial-control interfaces. For layout, the charge-pump capacitors must be placed close to their associated pins, and the interface ground must connect to the equipment chassis through the strategy specified by the application EMC standard. Cable routing and enclosure grounding often determine real-world ESD and EFT performance more than the IC rating alone. This page combines manufacturer specifications, verified distributor availability information, drop-in socket-compatibility candidates, and practical interface-design guidance to support component selection and PCB implementation.

ADM202JN - Dual 120kbps RS-232 Transceiver | Analog Devices

The Analog Devices ADM202JN is a dual-channel RS-232 line driver and receiver IC with two drivers, two receivers, a 120 kB/s transmission rate, and a 16-PDIP package. It operates from a single 5 V supply and uses an on-chip charge pump with 0.1 µF capacitors to generate ±10 V RS-232 output levels. The device is designed for legacy and industrial point-to-point serial interfaces requiring TIA/EIA-232-E and V.28-compatible signaling. An RS-232 transceiver is an interface IC that converts low-voltage digital logic levels into differential bipolar line voltages for transmission and converts received line voltages back into logic-compatible signals. The ADM202 belongs to the RS-232 transceiver class, which includes line drivers, line receivers, level-shifting circuitry, and charge-pump voltage generation. It is intended to bridge a host controller or UART with an external RS-232 connector while operating from a single 5 V rail. Key features include two RS-232 drivers, two RS-232 receivers, a 120 kB/s data rate, 0.1 µF charge-pump capacitors, and integrated on-board DC-DC conversion. The supplied data identifies the output levels as ±10 V and states that the device meets or exceeds TIA/EIA-232-E and V.28 specifications. The 16-PDIP package is a through-hole package suitable for conventional PCB sockets and legacy communication equipment. The ADM202 architecture combines digital input/output compatibility with analog line-driver and receiver functions. Its charge-pump converter avoids a separate negative supply for RS-232 transmission while reducing the external capacitor requirement to 0.1 µF. The receiver side translates the bipolar RS-232 signal into a logic-level output suitable for a UART or microprocessor. Exact propagation-delay, input-threshold, output-current, and absolute-maximum values are not supplied in the verified excerpts and are marked for data collection rather than inferred. Typical uses include industrial serial adapters, data-acquisition equipment, service interfaces, test systems, embedded control consoles, and legacy peripheral connections. The part is most appropriate where the system already uses a true RS-232 physical interface and requires a compact two-channel transceiver rather than a modern differential bus such as RS-485. The ±10 V output capability helps provide the voltage swing expected by RS-232 receivers while the single 5 V supply simplifies system power design. Designers should verify the external charge-pump capacitor connection, pin orientation, logic-level compatibility, receiver hysteresis, and cable-side protection against the manufacturer datasheet. Do not treat RS-232 as a long-distance differential communication standard; cable length, grounding, connector pin assignment, and EMI conditions still determine practical reliability. The supplied data also indicates that the ADM202JN is an obsolete-style 16-DIP product, so sourcing and lifecycle confirmation should be checked before new production commitments. This product page combines the verified Analog Devices function description, distributor package identification, and public cross-reference leads with engineering-focused selection, application, and sourcing guidance. It distinguishes verified facts from missing parameters and does not invent pricing, pin names, or electrical values that were not present in the supplied data.

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.

The Analog Devices ADM206AR is a +5 V powered CMOS RS-232 transceiver with four drivers, three receivers, a shutdown pin, and an enable pin in a 24-SOIC package. Its specified 200 kbps data rate, 0.1 µF charge-pump capacitor requirement, 9 V output swing, and 30 V receiver input levels make it suitable for compact single-supply serial interfaces where ±12 V is unavailable. What is an RS-232 transceiver? An RS-232 transceiver combines line drivers and receivers that translate between digital logic levels and bipolar serial-interface signals. The driver channels transmit data, while receiver channels interpret incoming RS-232 levels. In the broader hierarchy, it is an interface transceiver, a communications IC, and a semiconductor designed for point-to-point serial data links. The ADM206AR is especially useful when a system has only a +5 V supply but requires the voltage levels and noise immunity associated with RS-232. Its four-driver and three-receiver arrangement can serve several channels where space is constrained. The manufacturer describes the device as a 200 kbps RS-232 transceiver with an integrated shutdown function and enable control. Operationally, the device uses charge-pump circuitry to generate the bipolar signal levels required by RS-232 from the single positive supply. The verified product description identifies 0.1 µF capacitors for charge-pump operation and reports a 9 V output swing with a +5 V supply. The receivers accept input voltages identified in the source data as extending to 30 V, which helps when the interface cable introduces larger transients or sees voltage offsets. Typical applications include serial adapters, embedded instrumentation, industrial control links, test equipment, and legacy computer peripherals. Because the ADM206AR includes both shutdown and enable pins, it can support systems that need controlled power states or channel management. The 24-SOIC package also remains convenient for through-hole and mixed-signal PCB assembly. When laying out the circuit, place the charge-pump capacitor and interface protection components according to the manufacturer’s recommended layout and keep the RS-232 connector-side traces physically separated from sensitive logic where practical. Confirm the exact receiver enable, shutdown, and channel pin assignments against the official ADM206 datasheet before final PCB release. This page combines verified manufacturer and distributor information, package-aware replacement guidance, interface design considerations, and application-oriented selection context. It is intended to help engineers evaluate the ADM206AR against alternatives without assuming that every RS-232 IC is pin-compatible.

Analog Devices ADM206ARZ is a four-driver, three-receiver RS-232 transceiver designed for single 5 V operation, with 0.1 µF charge-pump capacitors and a 200 kbps data rate in a 24-pin SOIC package. It uses on-board DC-to-DC conversion to produce approximately ±9 V output swings without requiring external ±12 V supplies, while operating from a 4.5 V to 5.5 V source. An RS-232 transceiver is an interface IC that converts digital logic-level signals into RS-232 line levels and receives RS-232 signals for conversion back to CMOS logic levels. Within the interface hierarchy, the ADM206ARZ belongs to the RS-232 transceiver class of communication interface ICs. It supports point-to-point serial links where ground and signal conductors connect two pieces of equipment over distances defined by the RS-232 electrical standard. The device provides four line drivers, three receivers, a shutdown pin, and an enable pin. Its advertised 200 kbps maximum data rate suits moderate-speed data acquisition, industrial control, instrumentation, and equipment interfaces. The ±9 V charge-pump outputs provide greater noise margin than a simple ground-referenced driver would offer, while the low-power design is rated at 15 mW under the stated operating condition. The 0.1 µF external charge-pump capacitor requirement simplifies external power-supply design compared with discrete RS-232 level-shifter networks. A single 5 V rail powers the receiver, driver, and charge-pump circuitry, reducing board area and assembly complexity. Control inputs support shutdown and operating-state management when a system needs to reduce power or isolate the interface. Typical applications include industrial serial consoles, laboratory instruments, barcode and identification equipment, embedded control systems, and point-to-point links between a controller and peripheral. Because the interface uses single-ended RS-232 signaling, the board layout should keep the driver outputs and receiver inputs away from switching nodes and noisy analog sections.

ADM206EAR - 4/3 RS-232 Transceiver, 200 kbps | Analog Devices

Analog Devices ADM206EAR is a +5 V CMOS RS-232 transceiver with four line drivers, three line receivers, a shutdown pin, and an enable pin in a 24-pin SOIC package. It supports data rates up to 200 kbps and uses 0.1 uF charge-pump capacitors for single-supply operation. The ADM2xxE family is designed for robust point-to-point serial interfaces where a modern logic-level UART must connect to an RS-232 port. An RS-232 transceiver is an interface IC that combines voltage-level drivers and receivers with charge-pump circuitry. The drivers convert low-voltage CMOS logic signals into RS-232 bipolar levels, while the receivers convert bipolar line signals back into CMOS-compatible levels. As a member of the interface IC hierarchy, the ADM206EAR sits between UART controllers and external RS-232 equipment, providing signal translation, port direction control, and electrostatic-discharge protection. Key features include four drivers, three receivers, operation from a single +5 V supply, and data rates up to 200 kbps. The shutdown and enable controls support power management and port isolation. According to the Analog Devices ADM206E product information, all devices in the family conform to EIA-232E and CCITT V.28 specifications. Their integrated protection is intended to withstand harsh electrical environments and reduce the need for separate TransZorbs on protected RS-232 lines. The device uses on-chip charge pumps to generate the positive and negative voltages required by RS-232 drivers from one +5 V source. Charge-pump capacitors should be connected exactly as shown in the manufacturer application circuit. Because the line interface uses bipolar voltage levels, the device is intended for RS-232 ports, not RS-485 or RS-422 multidrop networks. Driver and receiver enable controls can suppress unwanted activity during shutdown or when multiple interfaces share a system enclosure. Typical uses include industrial serial consoles, laboratory instrument control, point-of-sale terminals, data-acquisition equipment, and embedded systems connected through legacy RS-232 ports. The four-driver and three-receiver arrangement supports several unidirectional channels or a mixture of data and control lines. Because maximum cable length and data rate are inversely related, the selected baud rate and cable type should be checked against the target RS-232 application. For a robust layout, place the 0.1 uF charge-pump capacitors close to their designated pins, route each RS-232 line directly to its connector, and keep unprotected logic-side traces away from cable transients. The datasheet pin-description table should be used to verify every connection before manufacturing. The enable and shutdown pins also require defined logic levels during reset so the drivers do not start in an unintended state. This product page combines the manufacturer interface overview, package information, ordering details, replacement guidance, and practical PCB design notes. It also distinguishes the exact ADM206EAR from related ADM2xxE devices whose driver counts, shutdown behavior, enable architecture, or package differ. The result helps engineers determine pin compatibility, data-rate suitability, and the correct role for each RS-232 channel before committing a board layout.
