A54SX72A-PQ208

A54SX72A-PQ208 - 108K Gate Antifuse FPGA, 208-PQFP | Microchip

The Microchip Technology A54SX72A-PQ208 is an SX-A family antifuse FPGA with up to 108,000 system gates, 4,024 logic cells, 171 user-programmable I/O pins, and a toggle frequency up to 217 MHz, housed in a 208-pin PQFP (208-BFQFP) package. It operates from a 2.25V to 5.25V supply over a commercial 0C to +70C temperature range. An antifuse FPGA is a type of field-programmable gate array in which the programmable interconnect is formed by one-time-programmable antifuse elements rather than SRAM configuration cells or flash. Within the programmable logic hierarchy (FPGA -> programmable logic device -> digital IC), antifuse devices occupy the non-volatile, configuration-retention niche: the programmed connections are permanent, so no external configuration ROM is required at power-up, and the bitstream cannot be read out of the device. Key features of the A54SX72A-PQ208 include the 0.25 um CMOS process technology, up to 2,012 dedicated flip-flops, multiple global and quadrant clock networks (CLKA, CLKB, and QCLK), and low static power consumption enabled by the antifuse architecture. The 171 available user I/O on the PQ208 package supports mixed-voltage interfacing across the wide 2.25V to 5.25V supply range. The SX-A architecture uses a sea-of-modules fabric with combinational and sequential logic modules, giving deterministic interconnect delays that simplify timing closure compared with SRAM FPGAs. According to the Microchip SX-A Family FPGAs datasheet, the A54SX72A delivers high performance at low power, and the family is positioned for integrating multiple functions into a low-cost, single-chip solution. Typical applications include industrial control and automation, glue logic integration and system consolidation, bridge and interface functions, and prototyping for the rad-tolerant RT54SX-S space devices, which Microchip documents as pin compatible in CQ208/PQ208 packages. A key design consideration: antifuse devices are one-time programmable, so all functional verification must be completed in simulation before programming; budget spare I/O and logic capacity of at least 20% for design changes. This page synthesizes distributor pricing, same-package drop-in speed/temperature-grade variants, and practical design notes not consolidated in the manufacturer datasheet.

A54SX72A-PQ208I - 108K-Gate Antifuse FPGA, 208-PQFP | Microchip
A54SX72A-PQ208I

A54SX72A-PQ208I - 108K-Gate Antifuse FPGA, 208-PQFP | Microchip

The Microchip Technology A54SX72A-PQ208I is a 108,000-system-gate antifuse FPGA from the SX-A family, delivering up to 171 user-programmable I/O pins, 2,012 dedicated flip-flops, and up to 217 MHz system performance in a 208-pin BFQFP (PQ208) surface-mount package. It operates from a 2.25V to 5.25V supply and is rated for the industrial temperature range of -40C to +85C. An antifuse FPGA is a type of field-programmable gate array in which programming connections are permanent one-time fuses. Unlike SRAM-based FPGAs, antifuse devices retain their configuration through power cycles without an external configuration memory, and the programming element adds very little routing capacitance, which yields inherently low power, high speed, and improved resistance to configuration corruption - placing this device in the broader hierarchy of FPGA, programmable logic, and semiconductor integrated circuits. Key features include the 0.25 um CMOS process technology, 4,024 logic cells organized into 6,036 logic array blocks (LABs), multiple global clock networks (CLKA, CLKB and quadrant QCLK routing), and the single-chip, non-volatile architecture that removes the external boot flash required by SRAM FPGAs. These traits make the SX-A family a cost-effective solution for integrating multiple functions into one low-power, high-performance device. Architecturally, the A54SX72A is the largest member of the SX-A family, using Actel's (now Microchip) antifuse routing fabric with dedicated hard-wired interconnect that minimizes switching capacitance and pin-to-pin delays. The quadrant clock structure described in the SX-A Family FPGAs datasheet enables predictable clock skew across large designs, while the sea-of-modules routing supports high gate utilization. Typical applications include telecommunications and networking line cards, industrial automation controllers, consumer electronics glue logic integration, and aerospace/defense designs that benefit from the configuration immutability of antifuse technology. When designing with this part, note that antifuse programming is permanent: design changes require a new device, so fully verify timing in Libero/Designer before programming. Also confirm I/O current budgeting across the 171 available user I/O. This page synthesizes distributor pricing, drop-in alternatives, design notes, and comparison data not found in the manufacturer datasheet, giving engineers and buyers a single authoritative reference for the A54SX72A-PQ208I.

A54SX72A-PQ208M

A54SX72A-PQ208M - 108K-Gate SX-A Antifuse FPGA | Microchip

The Microchip Technology (Actel/Microsemi) A54SX72A-PQ208M is a 108,000-gate SX-A family antifuse FPGA with up to 2,012 dedicated flip-flops and 171 user-programmable I/O pins, housed in a 208-pin PQFP (208-BFQFP) surface-mount package operating from a 2.5V core supply. An antifuse FPGA is a type of field-programmable gate array whose interconnect is permanently configured at power-up programming time via antifuse links. Unlike SRAM-based FPGAs from Xilinx or Intel (Altera), antifuse devices are non-volatile and one-time programmable: the configuration is stored physically in the silicon, requires no external configuration ROM, boots instantly, and is inherently resistant to configuration readback, making the SX-A family a historical choice for secure, high-reliability industrial and aerospace logic designs. Key features of the A54SX72A include 108,000 available system gates, a 0.25 um CMOS process technology, system-level toggle rates up to 217 MHz on the core, and up to 360 user-programmable I/O across the full family. The device provides multiple global and quadrant clock networks (CLKA, CLKB and QCLK resources) for low-skew clock distribution, and single-chip integration replaces multiple ASSPs or glue-logic devices for system-wide cost savings. Architecturally, the SX-A fabric consists of combinatorial modules and sequential modules arranged in clusters, with a fine-grained routing architecture. The 0.25 um process delivers low static power compared to SRAM FPGAs of the same era, and the antifuse interconnect adds near-zero routing capacitance, supporting performance with low power consumption. Typical applications include industrial control and automation, secure communications and encryption interfaces, military and avionics subsystems, test equipment, and bus-interface or bridge logic where instant-on, tamper-resistant, single-chip integration is valued. Designers should note that antifuse FPGAs are one-time programmable: a design change requires a new physical device, so thorough simulation before programming is essential. Also, being a legacy product line, new designs should verify lifecycle availability.

A54SX72A-PQG208A

A54SX72A-PQG208A - 108K Gate Antifuse FPGA | Microchip

The Microchip Technology (Actel/Microsemi) A54SX72A-PQG208A is a 108,000 system-gate antifuse FPGA from the SX-A family, offering up to 360 user-programmable I/O (171 I/O available in the 208-pin package), 2,012 dedicated flip-flops, and a 0.25 um CMOS process in a 208-pin PQFP (PQG208) package operating at a 2.5V core supply. An antifuse FPGA is a field-programmable gate array whose interconnects are permanently configured by electrically blowing antifuse links at programming time. Unlike SRAM-based FPGAs (Xilinx, Altera), antifuse devices are non-volatile, one-time programmable, and require no configuration ROM or boot sequence, which makes them inherently more resistant to configuration readback attacks and immune to configuration upsets at power-on. Within the FPGA hierarchy, the A54SX72A sits in the low-power, high-security, single-chip ASIC-replacement category. Key features include a sea-of-modules architecture with up to 6,036 logic cells, system performance up to 217 MHz, TTL/LVTTL/LVCMOS2/3.3V PCI and 5V PCI compatible I/O levels, quadrant clock inputs for low-skew clock distribution, and automotive qualification variants within the SX-A family. The 0.25 um CMOS process delivers low static power and high gate density at low cost. The A54SX72A implements logic in configurable Logic Modules (combinational and sequential) with dedicated flip-flops supporting high-frequency pipelined designs. The four quadrant clock pins (A, B, C, D) drive low-skew clock networks across the die. Because the antifuse fabric is programmed once, time-to-market beats ASIC development while achieving ASIC-like security and standby power. Typical applications include industrial control and automation, military/aerospace glue logic and co-processors, communications line cards, medical instrumentation, and automotive systems using the A-temperature-grade PQG208A variant. Design consideration: antifuse FPGAs are one-time programmable - reserve ample logic headroom (use the 72,000 typical gates of the 108K device budget) and validate the design fully before programming, since design changes require a new device. Note that the A54SX72A-PQG208 sister part is reported end-of-life (December 2025) by OnlineComponents; verify lifecycle on purchase.

An antifuse FPGA is a field-programmable gate array in which programmable interconnects are one-time-programmable antifuse elements. Unlike SRAM-based FPGAs, antifuse devices retain their configuration permanently with no external boot configuration memory, which reduces bill-of-materials cost, shortens power-up time, and improves design security because the bitstream is never stored externally. In the programmable logic hierarchy, the A54SX72A sits within the FPGA class alongside one-time-programmable and reprogrammable fabric devices. Key features include a 2.5V core supply with I/O supply support from 2.25V to 5.25V per distributor data, enabling direct interfacing with 3.3V and 5V legacy logic families. The segmented routing architecture delivers predictable interconnect delays, supporting the 217 MHz toggle capability reported by distributors. The non-volatile antifuse fabric also offers low static power consumption and inherent resistance to configuration readback attacks. The device is fabricated on a 0.25 um process and organized into logic modules with multiplexer-based combinational cells and register cells, a structure suited to wide-decode, state-machine, and glue-logic integration. Quadrant clock inputs (A, B, C, D per the Microchip SX-A datasheet) support multiple low-skew clock domains. Typical applications include industrial control and automation, communications line-card glue logic, aerospace and defense single-board computers where configuration volatility is unacceptable, and cost-reduction ASIC prototypes or bridge logic consolidating multiple ASSPs into one chip. Design consideration: because antifuse FPGAs are one-time programmable, thoroughly complete simulation and timing verification in Libero SoC before programming, and budget the programming service or in-house programmer into your production flow.

Key features include the 108K system gate capacity for integrating multiple logic functions into a single low-cost chip, the 217 MHz system speed supported by dedicated global and quadrant clock networks (CLKA, CLKB, QCLK), and the antifuse architecture which removes the need for an external configuration PROM and eliminates configuration bitstream loading time at power-up. Technically, the SX-A family uses a sea-of-modules architecture with combinational C-cells and sequential R-cells, implemented in a 0.25 um CMOS process. The device is designed in using Microchip's Libero SoC design suite (historically Actel Designer flow) and programmed at the board house or by the user with standard programming hardware. Typical applications include industrial control, networking line cards, glue logic integration,ASIC prototyping, and secure military/avionics systems where a non-volatile, single-chip programmable solution reduces BOM cost and board area. When designing with this device, remember the antifuse is one-time programmable - verify the design thoroughly in simulation before programming, and check that 2.5 V core and I/O voltage rails are properly sequenced.

ACPL-C790-500E - Precision Isolation Amplifier | Broadcom
ACPL-C790-500E

ACPL-C790-500E - Precision Isolation Amplifier | Broadcom

The Broadcom ACPL-C790-500E is a precision miniature isolation amplifier designed for current and voltage sensing in electronic power converters, packaged in an 8-SO Stretched (SSO-8) outline with a 6.8 mm body width. It is part of the ACPL-C79B/C79A/C790 family and offers a differential output with a typical small-signal bandwidth of 200 kHz and an isolation voltage rating suitable for high-voltage power electronics applications. The device is supplied in tape-and-reel packaging (suffix -500E) and is intended for surface-mount assembly on standard FR-4 boards. An isolation amplifier is an active analog component that combines an input-side amplifier, an isolation barrier (typically optical), and an output-side amplifier in a single package. It allows a small analog signal to be measured on a high-voltage or safety-isolated node and output as a ground-referenced analog signal. The category sits within instrumentation amplifiers (in-amps) -> operational amplifiers -> linear ICs -> power management and signal chain semiconductors. Isolation amplifiers are essential where a controller must measure current or voltage on a high-voltage bus (motor drives, solar inverters, EV traction) without galvanic connection to the high-voltage domain. Key features include a precision optical coupling mechanism, internal reference and gain-setting, differential output topology, and industry-standard SSO-8 footprint for drop-in layout reuse. The part is qualified for industrial and renewable-energy converter applications and is broadly used as a precision alternative to Hall-effect current sensors in motor drive and UPS designs. From a technical standpoint, the ACPL-C790-500E uses an optical isolation barrier that delivers high common-mode rejection (CMRR) and stable gain over temperature, enabling accurate phase-current measurement for field-oriented control (FOC) loops in three-phase motor drives. Compared with shunt-resistor + Hall sensor combinations, the optical isolation amplifier achieves tighter gain tolerance and lower temperature drift. Typical applications include motor-drive phase current sensing, solar inverter DC-bus and string-current monitoring, uninterruptible power supply (UPS) current measurement, EV charging station current sensing, and industrial servo amplifier analog front-ends. When designing with the ACPL-C790-500E, ensure adequate PCB creepage and clearance at the package sides, place the input-side filter capacitor close to the input pins, and follow Broadcom's reference layout for SSO-8 isolation amplifiers. Proper high-voltage spacing and reinforced insulation traces are required to realize the rated isolation voltage. This page synthesizes distributor pricing, drop-in alternatives (including -Q1 and reel-packaging siblings), and practical design notes not found in the manufacturer datasheet alone, providing an SEO/GEO/AEO-optimized reference for engineers sourcing isolation amplifiers.

ACPL-C87BT-000E

ACPL-C87BT-000E - Automotive Precision Isolation Amplifier | Broadcom

The Broadcom ACPL-C87BT-000E is an automotive-grade precision optically isolated amplifier designed for high-accuracy DC and AC voltage sensing across an isolation barrier. It integrates a sigma-delta (Σ-Δ) analog-to-digital converter, chopper-stabilized amplifiers, and a fully differential circuit topology in a stretched 8-pin SO (SO-8 Stretched) package, delivering ±1% gain accuracy, 100 kHz bandwidth, and 5 kV RMS isolation voltage. An isolation amplifier is a specialized analog isolation device that combines a high-impedance front-end, a galvanic isolation barrier (optical, magnetic, or capacitive), and an output stage that reconstructs a clean, isolated analog or bitstream signal proportional to the input. ACPL-C87AT/C87BT parts belong to the broader category of isolation amplifiers, sitting architecturally between shunt-resistor-based current-sensing chains and downstream ADCs, motor-control DSPs, or safety-monitoring MCUs. They solve ground-loop and high-common-mode-voltage problems in motor drives, battery management, and renewable-energy inverters. The ACPL-C87BT-000E features a 2 V linear input range with 1 GΩ input impedance (minimizing loading of high-impedance dividers), 15 kV/µs common-mode transient immunity (CMTI), and an active-high shutdown pin that cuts IDD1 to 15 µA. The sigma-delta modulator output stream can be filtered externally by an MCU's SINC³ decimation filter, or post-processed by a dedicated filter IC, enabling flexible resolution-versus-latency tuning. Single 5 V supply operation simplifies power-tree design. The device uses Broadcom's proven optical-coupling technology, where an LED emitter is modulated by the input differential amplifier and sensed by a photodiode receiver on the isolated side. Chopper stabilization cancels the amplifier's input offset drift over temperature, while the fully differential signal path provides excellent isolation-mode noise rejection in the harsh EMI environments of IGBT bridge circuits. Typical applications include isolated DC-bus voltage sensing in motor drives, battery-pack voltage monitoring in EV/HEV battery management systems (BMS), solar inverter string-voltage telemetry, and isolated analog front-ends in industrial PLCs. Designers select this part when system-safety isolation (reinforced) is mandated by IEC 61800-5-1 or UL 1577. Key design considerations include the external clocking requirement for the sigma-delta modulator, LED-current-setting resistor calculation (RLED), and the trade-off between decimation-filter order and output settling time. Decimation order SINC³ with a 10 MHz modulator clock and 256 oversample ratio yields an effective 39 kHz output rate with 14-bit ENOB.

AD - Generic AD Prefix Component | Cross-Reference Search
AD

AD - Generic AD Prefix Component | Cross-Reference Search

The component designated by the partial part number string "AD" is not a discrete, orderable electronic component. It is a two-letter prefix that appears across thousands of part numbers from multiple manufacturers, most notably Analog Devices (ADI) and the historical A&D company. In the context of electronic components, a "part number prefix" or "base MPN" is the leading alpha-numeric sequence used by a manufacturer to identify a device family before adding suffix codes that specify package, temperature grade, tape-and-reel packaging, or screening level. For example, Analog Devices uses prefixes such as AD8221, AD9854, AD9361, and ADuM3150 to group precision amplifiers, direct-digital synthesizers, RF transceivers, and digital isolators respectively. The two-letter string "AD" alone therefore maps to no single silicon device. Key characteristics of the "AD" prefix include: (1) it spans mixed-signal ICs, sensors, converters, amplifiers, isolators, and processors, (2) it has no single package, pinout, or electrical specification, and (3) it is used by at least two distinct semiconductor companies whose product lines share no common parametric ground. Treating "AD" as a discrete MPN returns ambiguous results from distributor databases such as Octopart, DigiKey, and Mouser. Engineers encountering "AD" in a BOM, schematic, or legacy document should first determine whether the intended MPN is an Analog Devices part (the dominant interpretation) or whether the two letters form only a marking code on a third-party device. Analog Devices marking codes commonly use the letters "AD" on packages such as SOT-23 and SC-70 where space constraints prevent full MPN printing. Typical next steps when "AD" appears in source documentation include: consulting the surrounding context (schematic reference, BOM line, manufacturer logo), searching the manufacturer's part-number decoder, and verifying the full MPN against the authoritative component database. When designing with any AD-prefixed part, always confirm the full MPN against the manufacturer datasheet before sourcing. A truncated or misread MPN causes wrong-footprint board builds, parametric mismatches, and avoidable supply-chain cost. This page exists as a disambiguation entry for the "AD" string; it does not represent an orderable component. For specific specifications, request the full MPN from your engineering documentation.

AD1376KD

AD1376KD - 16-Bit 17us SAR ADC | Analog Devices | Hermetic DIP-32

The Analog Devices AD1376KD is a complete 16-bit successive-approximation analog-to-digital converter with on-chip reference, internal clock, and laser-trimmed thin-film scaling resistors, housed in a 32-pin hermetic ceramic side-brazed DIP package (32-BBDIP-H). The device integrates the reference, clock, and thin-film resistors so engineers can drop it onto a board without building a separate reference or SAR timing network. It converts a unipolar 0-10V (or ±5V, 0-20V) input to a 16-bit parallel word with a maximum linearity of ±0.003% (1 LSB at 16 bits). A SAR ADC (successive-approximation register analog-to-digital converter) is a precision data converter category that performs one binary decision per clock cycle using an internal DAC and comparator, settling to full resolution in a fixed number of cycles. SAR converters sit between sigma-delta (slower, higher-resolution) and flash (fastest, lowest-resolution) in the data-converter hierarchy: they offer 12-20 bits of resolution at 10s to 100s of ksps with no pipeline delay, which makes them ideal for multiplexing multiple channels and for event-triggered sampling in industrial and instrumentation systems. Key features include ±0.003% (1 LSB) maximum nonlinearity, no missing codes to 14 bits over the full operating temperature range, a fast 17us (AD1376KD) to 14us (AD1377) conversion time, adjustable internal clock rate, and both parallel and serial digital outputs. The 32-BBDIP-H package is a hermetically sealed ceramic DIP, suitable for military, aerospace, and harsh-environment applications where plastic packages would outgas or fail. The AD1376/AD1377 architecture uses a precision buried-zener reference and a thin-film resistor ladder for the internal DAC, giving 16-bit monotonic conversion with excellent long-term stability. The internal clock is adjustable via an external trim potentiometer, allowing designers to trade conversion speed for power dissipation. Digital I/O is TTL-compatible and can be read as parallel or serial data. Typical applications include industrial process control, military and aerospace instrumentation, precision data acquisition front-ends, multiplexed data-logging systems, and bench-top laboratory instruments where a complete, self-contained 16-bit ADC saves board space and design time. When designing with this device, note the +/-15V and +5V analog supply requirements (separate AGND and DGND pins) and provide adequate decoupling at the supply pins; the input signal must be driven from a buffer amplifier with low output impedance to avoid conversion errors caused by the ADC input current transients. This page synthesizes distributor pricing, drop-in same-brand AD1376/AD1377 family alternatives, and practical design guidance not aggregated in any single manufacturer datasheet, helping engineers select, source, and implement this legacy hermetic 16-bit SAR converter.

AD14/085-0 - 8-bit ADC, 1-Channel | Analog Devices Inc.
AD14/085-0

AD14/085-0 - 8-bit ADC, 1-Channel | Analog Devices Inc.

The Analog Devices Inc. AD14/085-0 is a monolithic 8-bit, single-channel analog-to-digital converter (ADC) input device. Per the verified distributor listings, the part is described as an "8X1" ADC channel architecture, providing compact signal conversion for embedded systems. The device is sourced exclusively through the authorized Analog Devices distribution channel and is housed in a proprietary IC package suitable for industrial and instrumentation use. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts real-world analog signals - such as sensor voltages, audio waveforms, or RF envelopes - into discrete digital codes that a microcontroller or DSP can process. ADC categories are typically segmented by resolution (8-bit, 10-bit, 12-bit, 16-bit, 24-bit), architecture (SAR, Sigma-Delta, Flash, Pipelined), and channel count. The AD14/085-0 sits in the 8-bit, single-channel category - the most common ADC tier for low-resolution sensor reading, panel-meter, and control-loop applications. Key features reported across distributor listings confirm the part as a single-channel (8X1) ADC input from Analog Devices Inc. The "085-0" part of the MPN typically denotes the speed grade and temperature range within Analog Devices' legacy AD14 family nomenclature. As an 8-bit converter, the device provides 256 discrete quantization levels (LSB = VREF/256), making it suitable for coarse measurements such as temperature sensing, battery monitoring, panel meters, and digital potentiometer feedback loops rather than precision instrumentation. The AD14/085-0 belongs to the broader AD14 ADC family from Analog Devices, which historically targeted cost-sensitive embedded conversion applications.

AD1555BPRL

AD1555BPRL - 24-Bit Sigma-Delta ADC with PGA | Analog Devices

The Analog Devices AD1555BPRL is a 24-bit fourth-order sigma-delta analog-to-digital converter with an integrated programmable gain amplifier (PGA), housed in a 28-pin PLCC package. It delivers 116 dB minimum / 120 dB typical dynamic range, 256 kHz maximum sampling rate, and a 80 nV/√Hz low input noise floor for high-precision measurement applications. An ADC (Analog-to-Digital Converter) is a semiconductor device that converts continuous analog signals into discrete digital codes. Sigma-delta (Σ-Δ) ADCs use oversampling and noise-shaping to achieve very high resolution and dynamic range, making them ideal for low-frequency precision measurement. Within the converter hierarchy, the AD1555BPRL belongs to the precision-measurement ADC family, which sits under data converters and the broader category of analog signal chain ICs. Key features include 80 nV/√Hz input-referred noise at 4 ms conversion time with a gain of 128, −111 dB maximum / −120 dB typical total harmonic distortion, and 122 dB intermodulation distortion. The integrated PGA supports gains up to 128, allowing direct interfacing with low-level bridge, strain-gauge, and thermocouple sensors without external instrumentation amplifiers. The ones-density bitstream output pairs with the AD1556 digital filter to reconstruct 24-bit conversion results. The fourth-order modulator uses a switched-capacitor architecture with continuous-time calibration for low drift over temperature. The device operates from ±5 V analog supplies and a +3 V to +5 V digital supply, with the PLCC-28 package providing a thermal resistance suitable for industrial environments from −40 °C to +85 °C. Typical applications include seismic instrumentation, weigh scales, high-precision industrial process control, and low-frequency vibration analysis. The 120 dB dynamic range enables direct digitization of bridge outputs without front-end gain stages. When designing with this device, pair the AD1555BPRL with the AD1556 companion digital filter ASIC to obtain a complete 24-bit ADC solution. Provide separate analog and digital ground planes, decouple each supply pin with 10 µF tantalum in parallel with 0.1 µF ceramic, and keep the analog input traces away from the digital bitstream output to preserve 120 dB dynamic range.

AD1674AR-REEL

AD1674AR-REEL - 12-Bit 100kSPS Complete ADC | Analog Devices

The Analog Devices AD1674AR-REEL is a complete, multipurpose 12-bit successive-approximation analog-to-digital converter (ADC) with an integrated sample-and-hold amplifier (SHA), a 10 V on-chip voltage reference, an internal clock and three-state output buffers for direct microprocessor interface, packaged in a 28-SOIC (7.50 mm body width). It delivers 100 kSPS throughput and is specified over the industrial -40C to +85C temperature range. The 28-pin SOIC (R-28) form factor uses Tape & Reel (REEL) packaging per Analog Devices ordering code. A successive-approximation ADC is a converter architecture that resolves one bit per internal clock cycle by comparing the sampled input against a precision DAC. Modern SAR ADCs integrate a sample-and-hold amplifier on the input so the user does not have to drive the converter with a continuous low-impedance signal - this widens the input bandwidth and simplifies the front-end filter design. The AD1674 fits into the converter hierarchy as: ADC -> SAR ADC -> monolithic complete ADC -> data-acquisition IC, and bridges industrial analog signal chains and 8-/16-bit microprocessor buses. Key differentiating features of the AD1674 include its complete monolithic integration (SHA + reference + clock + buffers in one die), industry-standard pinout pin-compatible with the legacy AD574A and AD674A, 10 us conversion time, three-state bus outputs with logic/control pins (CS, R/C, CE, A0, 12/8, STS) for direct 8-bit or 16-bit microprocessor hookup, and bipolar/unipolar input ranges via pin strapping. The internal buried-Zener reference trims to 10.00 V +/-0.5%, eliminating external reference components. Internally, the converter uses a precision thin-film DAC array, a high-speed comparator and a successive-approximation register clocked by an internal RC oscillator. The SHA front-end can acquire full-scale inputs in under 1 us, supporting the 100 kSPS throughput; the wideband sample-and-hold supports 12-bit accuracy across the full Nyquist bandwidth, so AC inputs up to 50 kHz can be digitized with negligible aperture distortion. Output coding is user-selectable for unipolar (0-10 V, 0-20 V) or bipolar (-5 V to +5 V, -10 V to +10 V) input ranges. Typical applications for the AD1674AR-REEL include industrial process-control data acquisition front ends, instrumentation and measurement systems, multichannel analog input boards with multiplexer scanning, scan-digitizer cards and legacy AD574A/AD674A designs that need a faster, SHA-equipped upgrade. The R-grade (industrial) temperature range and 28-SOIC footprint make it a drop-in replacement for older designs requiring faster sample rates without a layout change. When designing, note that the converter draws significant supply current - place 10 uF tantalum and 0.1 uF ceramic bypass capacitors close to the AVcc and DVcc pins and use a star-ground topology. Avoid switching the analog input while STS (status) is low; violating this timing window injects conversion errors.

Delivering 100 kSPS throughput in a 28-pin SOIC (Wide) package, the AD1674BR is specified over the -40C to +85C industrial temperature range and supports both unipolar (0-10 V, 0-20 V) and bipolar (±5 V, ±10 V) input ranges. A successive-approximation-register (SAR) ADC is a converter architecture that resolves each conversion in a fixed number of internal comparison cycles, producing deterministic latency and excellent DC accuracy at moderate sample rates. SAR ADCs sit in the converter hierarchy between flash converters (fastest, lowest resolution) and sigma-delta converters (highest resolution, lowest bandwidth). The AD1674 family occupies the precision mid-speed tier, replacing AD574A/AD674A designs where sampling is required. Key performance features include guaranteed AC and DC specifications, ±1/2 LSB integral nonlinearity (typical), and full Nyquist bandwidth acquisition through the front-end SHA. The AD1674 is pin-compatible with the industry-standard AD574A and AD674A but adds the sampling front-end and faster 10 microsecond conversion time. Bipolar input ranges are factory-trimmed, eliminating external scaling resistors in many measurement paths. The AD1674BR is implemented using Analog Devices' BiMOS II process, which combines bipolar analog circuitry with CMOS logic on the same die. This monolithic integration is what enables the integrated SHA, reference, clock and tri-state bus interface without external components. Three-state output buffers simplify connection to common 8-bit and 16-bit microprocessor and DSP data buses. Typical applications include industrial process-control analog input modules, data-acquisition front-ends, precision instrumentation, vibration and seismic signal digitisation, and replacement of legacy AD574A / AD674A sockets where higher throughput is needed. With both AC and DC specifications guaranteed, the AD1674 is suitable for signal processing and traditional DC measurement paths. When designing with this part, ensure the analog and digital grounds are joined at a single star point near the device to avoid digital switching noise coupling into the analog input. Decouple VCC and VEE close to the pins with 10uF tantalum in parallel with 0.1uF ceramic, and observe the standard AD574A timing protocol for read and convert cycles. This page synthesises distributor pricing, same-brand drop-in alternatives and practical design notes that go beyond the manufacturer datasheet summary, giving engineers a single source for AD1674BR selection, sourcing, and substitution decisions.

It transports bidirectional synchronous PCM data, digital audio, clock, and synchronization signals over one unshielded twisted-pair differential cable. The verified product information identifies a 32-channel audio transceiver in a 7 x 7 mm 48-LFCSP package. An A2B transceiver is an automotive network interface that connects audio sources and receivers through a daisy-chained differential cable topology. It combines digital audio transport, clocking, synchronization, node discovery, and optional bus power in one interface. This places the AD2433 within the hierarchy of A2B transceiver, automotive network interface, audio interface IC, and integrated circuit. The AD2433 supports a direct point-to-point connection and a multi-node daisy chain, allowing one cable to serve more than two automotive audio nodes. Its single-pair architecture can reduce wiring weight compared with carrying separate clock, synchronization, and PCM signals. The I2S/TDM connection supports multichannel digital audio transfer, while the A2B link carries bidirectional synchronous PCM information and synchronization over the cable. A key feature of the AD2433WCCPZY20-RL is bus powering, which allows the main node to supply voltage and current to subordinate nodes over the same daisy-chained twisted pair used for communication. This is useful in automotive infotainment and distributed-audio systems where cable length, node count, and power-distribution constraints matter. The verified source also identifies the AD2433 as recommended for new designs. The AD2433 is suitable for automotive audio head units, cockpit controllers, audio amplifiers, digital sound processors, seat-zone audio nodes, navigation and telematics systems, and other vehicle infotainment platforms. The 48-LFCSP package helps support dense automotive electronic modules, although exact electrical and timing limits must be confirmed in the manufacturer datasheet. When laying out an AD2433 network, preserve the differential pair geometry and follow the manufacturer’s recommended termination, decoupling, grounding, and connector practices.

The Analog Devices AD2S82ALP is a monolithic variable-resolution resolver-to-digital (R/D) converter that delivers user-selectable 10-, 12-, 14- or 16-bit output word resolution in a 44-lead PLCC (J-leaded) surface-mount form factor. Packaged in a 16.59 x 16.59 mm PLCC-44, it integrates a Type II tracking loop, a velocity-output (VCO) section, a complementary direction output, and ESD-protected I/O rated at 2,000 V minimum (Class 2). A resolver-to-digital converter is a position-sensing signal conditioner that decodes the modulated sine/cosine signals from a rotary resolver stator into a parallel binary word representing absolute shaft angle. The R/D converter sits between a brushless resolver sensor and a host processor in the motor-control, robotics, and servo-loop signal chain, providing ratiometric conversion that is independent of excitation amplitude and immune to most wiring-induced drift. Key features of the AD2S82ALP include ±2 arc-minutes of angular accuracy at 16-bit resolution, user-programmable bandwidth, a typical 300 mW power consumption, BYTE SELECT and ENABLE pins for 8/16-bit bus compatibility, and INHIBIT capability for shared data-bus architectures. The tracking-loop dynamics - including reference frequency, maximum tracking rate, and acceleration tolerance - are set by external components selected by the designer. The device is built on a BiMOS II process that combines bipolar drive capability with CMOS logic for low quiescent current and high noise immunity. Ratiometric signal conversion is achieved through the synchronous demodulation of resolver SIN and COS windings, eliminating reference-amplitude-induced position errors and allowing the converter to operate with a wide range of resolver excitation amplitudes. Typical applications include CNC machine-tool spindle feedback, military and commercial servo systems, industrial robot joint-angle sensing, electric-vehicle traction motor commutation, and avionics flight-control position feedback. Aerospace and defense designs benefit from the converter's hermetic-grade robustness and Analog Devices' long-term support program. When designing with the AD2S82ALP, careful PCB layout around the resolver excitation amplifier and the SIN/COS analog front end is critical - keep analog grounds isolated and bypass the ±Vs and VDD pins with 0.1 µF ceramic plus 10 µF tantalum capacitors as close to the IC as possible.

AD2S82ALPZ

AD2S82ALPZ - Variable Resolution Resolver-to-Digital Converter | Analog Devices

The Analog Devices AD2S82ALPZ is a variable-resolution, monolithic tracking resolver-to-digital (R/D) converter with user-selectable 10-, 12-, 14-, or 16-bit resolution, supplied in a 44-terminal PLCC (J-Lead) package. It accepts sine and cosine resolver signals and converts angular position and velocity into a parallel digital word plus a velocity output, while consuming approximately 30 mA from a single supply. A resolver-to-digital converter (R/D converter or RDC) is a mixed-signal data acquisition IC that converts the analog angle information encoded on a brushless resolver (or synchro) into a digital position word. An RDC sits inside the larger category of data acquisition ADCs, but unlike a successive-approximation ADC that samples voltage, an RDC implements a Type-II tracking loop that continuously nulls the resolver inputs and reports shaft angle. AD2S82ALPZ is therefore the highest-precision member of the resolver-to-digital hierarchy, which itself falls under position/speed sensor signal conditioning in motor-control and motion-control designs. Key features include user-selectable resolution (10/12/14/16 bits), a parallel (byte-wide) digital interface, ratiometric conversion that eliminates absolute voltage errors, and a tracking bandwidth that the user sets with external R-C components. According to the manufacturer datasheet, accuracy is rated at ±2 arc-minutes in the 16-bit mode and the maximum tracking rate reaches 16.25 revolutions per second. The BiMOS II process combines bipolar precision analog blocks with CMOS logic on the same die, yielding monolithic integration without external sample/hold or sine/cosine multipliers. Typical applications include industrial servo amplifiers, robotics and CNC machine-tool spindle position sensing, electric-vehicle traction motor control, military/aerospace gimbal positioning, and high-resolution rotary feedback in renewable-energy pitch/yaw systems. The wide supply tolerance and temperature rating make it suitable for harsh-environment industrial installations. When designing with this device, allocate a small analog ground island under the resolver inputs and connect all VDD pins to a common +12 V (or +5 V) rail decoupled with 0.1 µF ceramics; the bandwidth-setting resistor/capacitor pair directly controls tracking rate and must be selected against the application’s worst-case slew.
