The Analog Devices ADUM6411BRSZ is a quad-channel digital isolator with integrated isolated DC-to-DC converter (isoPower), 3750 Vrms isolation, 150 Mbps data rate, and 75 kV/us CMTI, housed in a 24-lead SSOP package. The integrated isoPower stage eliminates the need for a discrete isolated supply by delivering adjustable regulated output between 3.15 V and 5.25 V at up to 80 mA load. What is a digital isolator with isoPower? A digital isolator with isoPower is a semiconductor device that combines galvanic isolation of high-speed logic signals with an integrated isolated DC-to-DC converter on the same silicon die. Within the broader hierarchy of isolation technology, the ADUM6411 sits in the iCoupler family (chip-scale micro-transformer isolation), positioned above optocouplers in speed and integration, and below discrete transformer-driver pairs in flexibility. Key features include four independent isolation channels, 150 Mbps maximum guaranteed data rate, 75 kV/us minimum common-mode transient immunity, and 25-year minimum isolation life at rated working voltage. The DC-to-DC converter output is adjustable via external resistor divider, supporting both 3.3 V and 5 V rails common in industrial and motor-drive applications. The 24-SSOP wide-body package provides 8 mm creepage/clearance for reinforced insulation per IEC 60747-17.

ADV202

ADV202 - JPEG2000 Video Codec | Analog Devices

The Analog Devices ADV202 is a single-chip JPEG2000 codec targeted at video and high-bandwidth image compression applications. It implements the JPEG2000 (J2K) ISO/IEC 15444-1 image compression standard and provides complete compression and decompression processing on one die. The device operates on rectangular pixel tiles, where a tile may contain a complete image up to the maximum supported size or only part of an image, making it flexible for HD and high-resolution still-image pipelines. The ADV202 is offered in a 144-ball BGA package with surface-mount assembly, and it was formerly branded as the ADV-JP2000. A JPEG2000 video codec is a hardware engine that encodes and decodes images using the wavelet-based JPEG2000 Part 1 standard. Unlike block-based JPEG, JPEG2000 employs a discrete wavelet transform followed by entropy coding to produce scalable, high-quality compressed streams. In a hardware codec such as the ADV202, the wavelet transform engine, entropy codecs, memory controller, and control processor are integrated on-chip, eliminating the need for a host DSP or external compressor in many systems. This is important for bandwidth-limited video links because one chip can compress 720p video or large still-frame imagery into a JPEG2000 stream and decompress it on the receive side. Key features include a dedicated video port with glueless connection to common digital video standards such as 720p, plus programmable framing and validation signals for other high-speed synchronous pixel formats. The entropy codecs support all features of JPEG2000 Part 1 except the optional Maxshift ROI. Patented SURF (Spatial Ultra-efficient Recursive Filtering) technology enables low-power, low-cost implementation. Internally, the ADV202 contains a wavelet transform engine, three entropy codecs, an on-board memory system, and an embedded RISC processor that manages bitstream syntax and host commands. From a system perspective, the ADV202 is a complete JPEG2000 compression/decompression solution. The tile engine accepts rectangular arrays of pixel samples, allowing trade-off between memory usage and image size. Because codec operation is tile-based, extremely large still images can be processed in manageable sections, while video can be streamed tile-by-tile. The embedded RISC processor handles host interfaces and entropy codec coordination, reducing external control complexity. Although the ADV202 is no longer recommended for new designs (NRND), its architecture remains the basis of the ADV212, the manufacturer-specified drop-in replacement, which adds JTAG/BSDL and cuts power by up to 50%. Typical applications include broadcast and professional video systems, medical imaging and diagnostic capture, security and surveillance recording, aerospace and UAV payload compression, industrial machine vision, and remote-sensing image archival. For each application, the ADV202's combination of glueless video input, tile-based JPEG2000 Part 1 processing, and single-chip integration reduces BOM size compared with DSP-plus-software implementations. Designers migrating to the ADV212 retain these system benefits because the footprint and functionality are equivalent. Design consideration: because the ADV202 is NRND, a new layout should target the ADV212. Confirm core and I/O supply voltages, maximum clock, power dissipation, and BGA ball map from the official 40-page datasheet before producing a footprint. Verify legacy firmware command compatibility when swapping an ADV202 for an ADV212 in an existing system.

ADV3221ARZ

ADV3221ARZ - 800 MHz 4:1 Analog Multiplexer | Analog Devices

The Analog Devices ADV3221ARZ is a production 800 MHz, 4:1 buffered analog multiplexer in a 16-lead SOIC package. It routes one of four selectable analog inputs to a single output using high-speed, double-buffered logic control. The device is designed for high-bandwidth signal routing where short switching time, low insertion loss, controlled impedance, and low crosstalk are important. Its advertised −3 dB signal bandwidth is 800 MHz for a 200 mV p-p input and 750 MHz for a 2 V p-p input, with channel switching below 20 ns to 1% settling. An analog multiplexer is a switching IC that connects one of several input terminals to a common output path. A 4:1 device such as the ADV3221 belongs to the broader analog switch and multiplexor hierarchy, where input isolation, signal integrity, bandwidth, and control timing determine whether it can preserve a waveform during channel changes. Unlike an unbuffered passive switch, the ADV3221 includes active output drive to maintain a controlled signal path at high frequencies. Key features include 2400 V/µs slew rate, low 75 mW power consumption from ±5 V supplies, and strong video performance, including 100 MHz operation with 0.1 dB video bandwidth variation according to the supplied datasheet excerpts. The manufacturer describes the ADV3221 as a high-speed, high-slew-rate buffered 4:1 analog multiplexer, making it appropriate for video routing, instrumentation, test systems, and other wideband signal paths. The ADV3221 and closely related ADV3222 family uses double-buffered logic, allowing a new selection to be prepared before the switching interval. This architecture supports controlled break-before-make transitions and makes timing easier to coordinate in multi-channel systems. Signal amplitude can influence the quoted bandwidth, so system designers should compare performance at their actual operating amplitude rather than relying only on the headline 800 MHz figure. Typical applications include video test and measurement equipment, high-speed data-acquisition front ends, broadcast and professional video routing, and wideband communication test paths. The 16-SOIC footprint is suitable for conventional surface-mount assembly, although high-speed layouts must minimize trace lengths and provide a controlled return path. The primary design considerations are supply decoupling, controlled-impedance routing, grounding, and careful interpretation of the input and output common-mode limits. Because the manufacturer excerpt describes performance at ±5 V, engineers should verify the complete electrical limits and dual-supply requirements in the official datasheet before committing to a system design. This page consolidates verified manufacturer and distributor information, source-backed application guidance, parameter comparisons, and practical implementation notes. It adds engineering context around bandwidth, switching behavior, packaging, and sourcing while clearly separating verified specifications from parameters that still require direct datasheet confirmation.

ADV3222ARZ

ADV3222ARZ - 800 MHz 4:1 Analog Multiplexer | Analog Devices

The Analog Devices ADV3222ARZ is an 800 MHz, buffered 4:1 analog multiplexer with a 16-lead SOIC package. It supports dual supplies from -4.5 V to -5.5 V or +4.5 V to +5.5 V, uses double-buffered logic, and provides signal bandwidth above 800 MHz for high-speed analog routing. Its channel switching reaches 1% settling in less than 20 ns. An analog multiplexer is an interface IC that selects one of several inputs and connects that input to a common output. A 4:1 device therefore routes one of four channels through one output. In the signal-chain hierarchy, the ADV3222ARZ is a multiplexer within analog switches and multiplexers, interface ICs, and semiconductor signal-routing devices. The buffered inputs reduce source-loading effects, while double-buffered control simplifies break-before-make switching and digital sequencing. Key performance includes greater-than-800 MHz -3 dB bandwidth at 200 mV peak-to-peak, 750 MHz at 2 V peak-to-peak, a 2400 V/s slew rate, and lower than -58 dB crosstalk at 100 MHz. Isolation reaches -67 dB at 100 MHz. The supplied search data also identifies a low-power value of 75 mW at plus or minus 5 V and video performance of 0.1 dB at 100 MHz. The high-speed architecture is appropriate when preserving amplitude, edge rate, and isolation across several RF, video, pulse, or instrumentation signals matters more than minimizing switch resistance. Because the device is buffered rather than a simple low-resistance mechanical or MOS switch array, the selected channel presents an active drive path and requires careful impedance matching, termination, and control timing. Its 16-SOIC format is compatible with conventional surface-mount assembly but needs adequate high-frequency layout discipline. Typical uses include high-speed test equipment, video routing, communications instrumentation, data-acquisition front ends, and clock or pulse-signal selection. The sub-20 ns settling specification is useful in sample-and-hold and pulsed-test systems, while the 800 MHz bandwidth supports high-frequency measurement paths. Engineers should preserve symmetric routing and define unused inputs according to the manufacturer datasheet. For PCB implementation, use a continuous ground plane, short interconnects, and decoupling close to the supply pins. Terminate the selected signal into the impedance expected by the next stage, control crosstalk between adjacent channels, and verify settling at the actual amplitude and frequency. The operating voltage and unused-pin details should be checked directly against the manufacturer datasheet before layout release. This page combines manufacturer and distributor information, verified package and frequency details, sourcing links, and engineering guidance. It separates confirmed values from unavailable information and avoids presenting generic cross-reference tools as proof of pin compatibility.

The ADV7171KS is appropriate when a design must preserve a digital video source while producing standard analog baseband output. The serial control interface simplifies integration with source-specific firmware, while the dedicated video encoder reduces the need for external DAC and encoding circuitry. Engineers should still verify clocking, sync polarity, pixel clock relationships, output loading, power sequencing, and analog video quality against the complete manufacturer datasheet before releasing a production layout. Typical applications include DVD playback systems, portable video equipment, digital still cameras, laptop computers, video games, and PC video or multimedia products. In these systems, the encoder can convert decoded digital video into PAL or NTSC-compatible analog signals for downstream display or capture equipment. The dedicated encoder also supports integration into compact consumer products where board area and external component count are important. A key design consideration is that analog baseband video requires careful PCB layout and signal-integrity control. Keep the encoder clock and digital-video traces away from sensitive output paths, provide clean power and ground connections, and follow the manufacturer’s recommended decoupling and output-network details. Because the supplied web data does not expose the complete electrical timing table, pin names, or exact operating limits, those values should not be inferred from generic video-encoder specifications. This page consolidates verified manufacturer and distributor information, including the ADV7171KS application context, package identity, family capabilities, and replacement-search results. It is intended to support component selection and engineering research while clearly separating verified facts from parameters that still require confirmation in the complete ADV7170/ADV7171 datasheet.

ADV7171KSU

ADV7171KSU 10-Bit PAL/NTSC Video Encoder | Analog Devices

Analog Devices ADV7171KSU is an integrated 10-bit digital video encoder that converts ITU-R BT.601/656 YCrCb 4:2:2 component data into standard PAL or NTSC analog baseband video. The device provides four video DAC outputs and is supplied in a surface-mount 44-pin TQFP package measuring 10 mm by 10 mm. Its primary function is to bridge a digital video source and legacy analog composite, S-Video, or component outputs. A video encoder is a signal-conversion semiconductor that accepts digital pixel data and generates an analog waveform accepted by PAL or NTSC display equipment. Within the product hierarchy, the ADV7171 is an interface IC and video encoder rather than a processor or display driver. The corresponding digital-video-to-analog-video conversion stage sits between a video source, such as a DVD controller or multimedia processor, and an analog video connector or display. According to the Analog Devices ADV7171 product page, the encoder supports 8-bit or 16-bit CCIR-601 4:2:2 component video input. Its four 10-bit DACs support PAL and NTSC generation, while its digital video input follows the BT.601/656 format identified in the provided product information. This integration reduces the need for external video DACs when a design requires both S-Video and composite or additional analog video outputs. The ADV7170 and ADV7171 family is positioned for high-performance DVD playback, portable video equipment, digital still cameras, laptop computers, video games, and PC video or multimedia systems. The supplied search data does not provide verified clock frequency, power-supply range, output voltage resolution, operating temperature, timing limits, or package dimensions beyond the 10 mm by 10 mm TQFP description, so those values are not inferred here. The main engineering concern is interface compatibility rather than power conversion. The source must supply correctly timed BT.601/656 YCrCb data, the PCB must route high-speed digital video signals without excessive distortion, and analog outputs must be terminated according to the selected PAL or NTSC standard. The exact clocking, synchronization, control-register, and DAC configuration procedure must be taken from the manufacturer data sheet rather than inferred from the order code. For procurement, ADV7171KSUZ and ADV7171KSUZ-REEL appear in the supplied cross-reference results as the same 44-pin device with compatible terminals and characteristics, but the KSUZ order codes may represent ordering or reel-packaging conventions rather than five distinct functional alternatives. This page therefore distinguishes verified function-level choices from packaging suffixes and does not present reel-code variants as separate engineering options. This page consolidates the supplied manufacturer description, distributor package information, cross-reference findings, application guidance, and unresolved-data warnings. It is intended to support engineering selection and sourcing while directing readers to the manufacturer data sheet for authoritative electrical limits, pin functions, register definitions, and timing specifications.

ADV7195KS

ADV7195KS - 3-Channel 11-Bit Video DAC Encoder | Analog Devices

The Analog Devices ADV7195KS is a triple high-speed digital-to-analog video encoder with three 11-bit DACs and a 10-bit digital data input interface. Designed for progressive-scan and HDTV video systems, the device accepts YCrCb data and supports 2 x 10-bit 4:2:2 or 3 x 10-bit 4:4:4 input formats. It is supplied in a 52-lead MQFP package identified by the KS package suffix. A video DAC is an interface-integrated data converter that transforms digital YCrCb video samples into three analog color-component outputs. Within the broader signal-chain hierarchy, the ADV7195 belongs to the video encoder family, which combines digital-to-analog conversion with color encoding. This makes it suitable for professional video equipment, broadcast infrastructure, display-generation systems, and other multichannel analog-video applications where three coordinated outputs are required. The verified part description identifies three high-speed video D/A converters with TTL-compatible inputs. It also identifies progressive-scan and HDTV encoder operation with a 10-bit data input. These features distinguish the ADV7195 from lower-resolution or single-channel DAC solutions. The manufacturer data supplied for this record does not include a complete electrical limit table, so individual voltage, timing, clock, output, and temperature values remain marked for data collection rather than being inferred. The device uses YCrCb component coding, with the verified input options covering 4:2:2 and 4:4:4 arrangements. In practical systems, the input architecture must match the source format and resolution. The three-channel organization supports separate analog outputs for the luma-related and chroma-related video signals, while the exact sync and blanking implementation must be established from the manufacturer datasheet and application schematics before layout is released. Typical uses include professional broadcast monitors, video test and measurement equipment, HDTV production infrastructure, progressive-scan display systems, and video signal-generation equipment. In each case, the ADV7195KS can combine a digital video source with three DAC channels while preserving the intended progressive-scan or HDTV signal architecture. System designers should still validate timing, DAC settling behavior, output compliance, and synchronization against their specific source and load requirements. The most important design consideration is interface verification. Because the available verification identifies a 52-lead MQFP package but does not provide a complete authoritative pin table, the pinout should be checked directly against the Analog Devices datasheet before PCB routing. Input timing, DAC output reference, supply rails, decoupling, and unused-pin handling must also follow the datasheet rather than assumptions based only on generic video-encoder practice. This page consolidates the verified ADV7195KS function, package information, lifecycle evidence, sourcing references, and cross-reference candidates into an engineering-focused product record. It also distinguishes confirmed drop-in alternatives from related encoder families that may require different packages or verification, helping procurement and design teams avoid treating functional similarity as guaranteed pin compatibility.

It accepts 10-bit YCrCb or RGB data, including 4:4:4 and 4:2:2 formats, and generates three analog component-video outputs compatible with EIA770.3. Its three DAC channels support output currents of 4.33 mA and 2.66 mA, while a serial bidirectional I2C control interface supports programmable operating modes. A video DAC is a semiconductor that converts digital pixel or component-video data into analog voltage or current signals for display, broadcast, projection, and video-processing equipment. The ADV7197 belongs to the broader digital-to-analog converter hierarchy, which includes video DACs, audio DACs, interface ICs, and signal-conversion semiconductors. In an HDTV signal chain, it bridges a digital video processor and an analog video output stage. Key features include three 11-bit DAC channels, support for 10-bit 4:4:4 YCrCb or RGB inputs, 10-bit 4:2:2 YCrCb input, programmable output modes, and operation from a +5 V or +3.3 V supply. The converter accepts HDTV data at 74.25 MHz or 74.1758 MHz, and its asynchronous timing mode accommodates other high-definition standards based on SMPTE274M or SMPTE296M. Technically, the ADV7197 integrates three separate high-speed video D/A converters with TTL-compatible inputs. Serial control over the bidirectional I2C port configures modes, while separate analog outputs support standard component-video generation. The architecture is intended for multimedia systems where multiple synchronized analog channels are required from one digital source. Typical applications include HDTV displays, projection systems, digital video equipment, high-resolution color graphics, image-processing systems, and instrumentation. In each case, the device serves as the final digital-to-analog conversion stage after video compression, scaling, or color processing. A key design consideration is signal integrity. The high-speed digital inputs, analog current outputs, clocking, and control bus require careful PCB partitioning and return-path planning. Designers should also preserve the device's specified supply range, input timing, output-current configuration, and external video-network implementation rather than assuming generic DAC pinout conventions. This page combines manufacturer specifications, observed distributor pricing, verified lifecycle information, and engineering selection guidance. It also distinguishes exact package/order variants from broader functional alternatives so obsolete designs can be migrated without conflating compatibility with mere feature similarity.

It is designed for multi-channel analog video acquisition, conversion, and reconstruction systems. A video codec is a mixed-signal interface IC that converts analog video into digital data and can also produce analog video outputs. In the signal-processing hierarchy, the ADV7202 belongs to the codec family, interface IC class, and broader data-conversion semiconductor category. Its five-input capability allows one device to support several standard-definition video sources, while its four DAC outputs support reconstruction or monitoring paths. The principal verified features include simultaneous sampling of up to five composite video inputs, 12-bit front-end digitizer resolution, four video DAC channels, and 12-bit/10-bit digital data capability. The package is specified as 64-pin LQFP, also described in search data as PQFP64 or plastic LQFP-64. This integration can reduce the number of separate converters required in a video system, although exact timing, voltage, clock, output-format, and thermal details must be confirmed from the manufacturer documentation. The architecture is suited to systems that need a consolidated analog-video interface rather than discrete converters. Simultaneous sampling is important when multiple composite signals must share a defined acquisition moment, while the multiple DACs provide parallel analog-output capability. Digital resolution, clocking, sync handling, and supported video standards remain critical system constraints that depend on the selected operating mode and the complete ADV7202 datasheet. Typical uses include professional video test equipment, broadcast video monitoring, surveillance-system interfaces, video capture hardware, and multi-source analog-video switching systems. The component is particularly relevant when the board must ingest multiple composite video streams and retain flexible digital processing before conversion back to analog. Product selection should also account for source format, required resolution, supported clock, interface voltage, thermal conditions, and system timing. A practical design review begins with the ADV7202 datasheet pinout, electrical tables, timing diagrams, and application guidance. PCB layout should preserve analog and digital return paths, provide appropriate decoupling, and route high-speed digital signals with controlled impedance. Since the verified data does not include complete pin assignments or operating limits, engineers should not infer those values from generic codec designs. This page combines verified product, package, interface, and sourcing information with transparent data gaps, procurement guidance, and application-oriented engineering context. It distinguishes confirmed ADV7202KST facts from unverified parameters so designers can evaluate the codec efficiently without mistaking distributor summaries for a complete datasheet.

The main feature set includes six NSV video DAC channels, 12-bit DAC resolution, a stated 216 MHz encoder rate, and support for high-definition and standard-definition formats. Its separate input ports allow a system designer to accommodate different digital word lengths without forcing one common bus width. The device can generate composite, S-Video, component, or RGB analog signals, reducing the need for several discrete conversion paths in a multi-output video system. The ADV7311 architecture combines digital video input, internal encoding and timing functions, and six high-speed NSV DACs on one monolithic chip. According to the Analog Devices ADV7311 product page, external circuitry is used for some standards and output requirements. Consequently, board-level planning must account for external synchronization, filtering, connector routing, grounding, and the selected analog-output topology rather than treating the IC as a standalone video output stage. Typical applications include SDI-to-analog video conversion, professional broadcast monitoring, video test equipment, digital signage with legacy displays, security-video installations, and video switchers supporting composite or component outputs. The broad output-format support is useful where one digital source must feed more than one analog destination. A critical design consideration is signal integrity. Digital data, synchronization signals, analog outputs, reference connections, and power planes should follow the manufacturer datasheet layout guidance. Keep sensitive routes away from switching nodes, use a continuous ground reference, and verify the chosen output network and external components against the required video standard before production. This page consolidates verified product capabilities, package information, sourcing links, and engineering guidance. It also distinguishes documented drop-in replacements from broad functional substitutes, helping engineers assess PCB compatibility before considering a migration.

The NSV architecture pushes DAC quantization noise above the video band, achieving effective >12-bit linearity with very low out-of-band noise. Typical applications include HDTV encoders, professional studio equipment, DVD and Blu-ray authoring, video capture cards, security DVRs, and industrial video recording systems. The wide format support allows a single encoder to replace several single-standard parts across standard-definition and high-definition product lines. When designing with the ADV7341BSTZ, observe the 64-LQFP power and ground pin layout carefully; provide a continuous ground plane and decouple each supply pin with 100 nF plus 10 uF bulk capacitors placed within 3 mm of the pin.

ADV7391WBCPZ

ADV7391WBCPZ - 10-Bit SD/HD Video Encoder, 32-LFCSP | Analog Devices

The Analog Devices ADV7391WBCPZ is a low-power, chip-scale 10-bit SD/HD video encoder providing three 10-bit high-speed video DACs in a 32-lead LFCSP (5x5 mm) package. According to the Analog Devices product page, this encoder accepts SD and HD digital video inputs and supports composite (CVBS), S-Video (Y-C), and component (YPbPr/RGB) analog outputs, making it suitable for set-top boxes, video players, and professional displays. An SD/HD video encoder is a mixed-signal IC that converts digital video data (typically from an MPEG decoder, FPGA, or media processor) into analog baseband signals that drive legacy television inputs, broadcast equipment, and industrial video displays. Within the broader signal chain hierarchy - video processor > video encoder > video DAC > analog video output - the ADV7391WBCPZ integrates the encoder function with on-chip 10-bit DACs, eliminating the need for external video DACs and reducing PCB area. Three integrated DACs are required because component video (YPbPr or RGB) needs three simultaneous analog channels. Key specifications highlighted in the product page and distributor listings include three integrated 10-bit video DACs, support for SD (NTSC/PAL/SECAM) and HD (720p, 1080i, 1080p at reduced DAC speeds) video standards, an operating voltage down to a single 1.8V digital/3.3V analog supply, and a small 32-lead LFCSP footprint rated for the industrial temperature range. The chip-scale 5x5 mm package also exposes a thermal pad for improved heat dissipation in enclosed chassis. The encoder core uses a high-speed digital video input port (typically 8/16/24-bit ITU-R BT.656 / SMPTE 274M / 296M) and on-chip PLL to derive pixel clocks, color subcarrier, and HD sample rates from a single reference. Integrated low-pass reconstruction filters remove DAC image frequencies without external components, simplifying the analog output network to a few series resistors and an output coupling capacitor. Typical applications include set-top box (STB) HDMI-to-analog output back-ends, Blu-ray/DVD player analog video outputs, automotive infotainment rear-seat displays, video surveillance DVRs, and professional broadcast monitor test patterns. The encoder is also used in industrial video test equipment where a clean, standards-compliant analog video reference is required. When designing with this part, allocate separate analog and digital ground planes joined at a single star point beneath the exposed pad, place the analog supply decoupling capacitors within 5 mm of the AVDD pins, and avoid routing digital video data lines under the DAC output traces to minimize crosstalk into the reconstructed analog signal.

Technically, the device operates from a 1.8V digital supply and a 3.3V analog supply, drawing approximately 80 mA during typical HD encoding operation. Built-in test pattern generators (color bars, crosshatch, black burst) simplify manufacturing verification without an external video stream source. Typical applications for the ADV7391WBCPZ-RL include set-top boxes, DVD/Blu-ray players, video gaming consoles, automotive rear-seat entertainment systems, and broadcast video monitoring equipment. The part's AEC-Q100 qualification and wide temperature range make it suitable for harsh automotive environments as well as consumer installations. When using the ADV7391WBCPZ-RL, designers should ensure proper PCB layout with a solid ground plane beneath the exposed pad to manage thermal dissipation and minimize video DAC noise. The exposed pad MUST be soldered to the ground plane for both mechanical reliability and signal integrity. Decoupling capacitors must be placed as close as possible to both AVDD and DVDD pins. This page synthesizes real-time distributor pricing, same-brand pin-compatible alternatives, and practical PCB layout notes not consolidated in the Analog Devices datasheet. All data was verified against the manufacturer datasheet (Rev. K) and three distributor sources on 2026-10-20.
