A54SX72A-FG484A - 108K-Gate Antifuse FPGA, 360 I/O | Microchip

The Microchip Technology (Microsemi/Actel) A54SX72A-FG484A is an SX-A family antifuse field-programmable gate array (FPGA) with 108,000 system gates, 360 user I/O, and a 484-ball Fine-Pitch Ball Grid Array (484-FBGA) package, operating from a 2.25V to 5.25V supply over 0C to +70C commercial temperature grades. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently programmed at power-up by blowing internal antifuse links. Unlike SRAM-based FPGAs, antifuse devices are non-volatile, immune to configuration readback, and require no external configuration ROM, placing them in the programmable logic hierarchy alongside flash-based and SRAM FPGAs as one-time-programmable (OTP) logic devices. Key features of the A54SX72A-FG484A include a 0.25 um process technology, system-level performance up to 217 MHz for the -A speed grade, 4,024 logic cells, and 360 available user I/O in the 484-ball FBGA footprint. The SX-A architecture uses a sea-of-modules structure with C-cells for combinatorial logic and R-cells for registered logic, supported by multiple global clock networks including CLKA, CLKB, and quadrant clock (QCLK) resources for low-skew clock distribution. The device integrates multiple functions into a low-cost, single-chip solution, delivering performance, security, and low power. Because the antifuse configuration is permanent and cannot be read back, the A54SX72A-FG484A offers inherent design security, a key differentiator versus SRAM FPGAs. Supply voltage tolerance of 2.25V to 5.25V simplifies mixed-voltage board design. Typical applications include glue logic integration, bus interfacing, industrial control, communications equipment, and aerospace/defense systems requiring non-volatile, secure, single-chip programmable logic, where the SX-A family decreases the premium for performance. Design consideration: antifuse FPGAs are one-time programmable - there is no design iteration on the same physical device, so verify timing and functionality thoroughly in simulation before programming production units.

A54SX72A-FG484I

A54SX72A-FG484I - 108K-Gate Antifuse FPGA, 484 FBGA | Microchip

The Microchip (Actel/Microsemi) A54SX72A-FG484I is an antifuse FPGA from the SX-A family offering 108,000 system gates, 6,036 logic cells (CLBs), and up to 360 user I/O in a 484-ball fine-pitch BGA (FBGA-484) package. It operates from a 2.5V core supply and supports system performance in the 217 MHz class for the standard industrial-temperature speed grade. An antifuse FPGA is a one-time-programmable (OTP) programmable logic device whose interconnect switches are permanently formed at programming time. Within the programmable logic hierarchy (FPGA -> field-programmable gate array -> programmable logic IC -> semiconductor), antifuse devices occupy the non-volatile, single-chip niche: unlike SRAM FPGAs they need no configuration ROM, and unlike flash FPGAs they cannot be reprogrammed, which delivers inherent resistance to bit-stream readback attacks. Key features include the SX-A families combination of performance, security, and low power emphasized by Microchip: a 0.25um/0.22um CMOS process, 2.5V operation that reduces dynamic power versus 3.3V-class FPGAs, and deterministic pin-to-pin timing enabled by the antifuse interconnect architecture. The 484-ball package with 1.0 mm ball pitch provides the high I/O count required for wide data-path and bus-bridging designs. Architecturally, the SX-A family uses a sea-of-modules structure with dedicated quadrant clock networks (CLKA, CLKB, and QCLK resources) documented in the SX-A family datasheet and Microchip application notes on A54SX72A quadrant clocks. Routing delays are fixed at programming, giving timing behavior closer to ASICs than to reprogrammable FPGAs. Typical applications include single-chip integration of glue logic and bus interfaces in industrial equipment, aerospace and defense designs where configuration readback protection matters, and telecommunication line cards needing many 5V-tolerant-style I/O and deterministic timing. The industrial-grade (I suffix) temperature rating suits factory-floor environments. When designing with the A54SX72A-FG484I, remember it is one-time programmable: validate your design thoroughly in simulation and, where practical, using the equivalent in-system debugging approaches before programming, and budget for a spare device in each board build. Follow Microchip programming and layout guidance for the FBGA package, including adequate decoupling of the 2.5V core rail.

An antifuse FPGA is a one-time-programmable (OTP) field programmable gate array in which programmable interconnect elements are permanently formed at programming time. Unlike SRAM-based FPGAs, antifuse devices require no configuration boot PROM, exhibit no configuration readback vulnerability, and offer inherently lower power and higher design security. Within the programmable logic hierarchy, the A54SX72A sits at the top of the Actel SX-A family, above the SX08A, SX16A and SX32A devices. Key features include 6,036 configurable logic modules, a maximum toggle rate of up to 217 MHz (172 MHz system clock operation with 1.8 ns combinatorial CLB delay per Microchip USA data), and multi-voltage I/O support for 2.5 V, 3.3 V and 5.0 V signaling. The wide supply range of 2.25 V to 5.25 V on I/O banks allows direct interfacing with legacy 5 V systems while retaining 2.5 V core operation for low power. The architecture is based on Actel's SX-A module fabric: combination and register modules arranged in clusters, with three dedicated global clock networks (CLKA, CLKB and quadrant clocks) for low-skew distribution, as documented in the Microchip SX-A Family FPGAs datasheet. Because interconnect is antifuse-based, routing resistance and capacitance are low, supporting predictable, near-ASIC timing for high-reliability and defense-oriented designs. Typical applications include military and aerospace programmable glue logic, industrial control, communications line-card interface bridging, and legacy system redesigns where 5 V-tolerant I/O, OTP security and no-boot-time configuration are required. Design consideration: because the device is one-time-programmable, programming errors cannot be recovered in-circuit - use the Actel/Microchip Libero design flow with thorough simulation before committing to device programming, and plan JTAG/STAPL programming access on the PCB.

A54SX72A-FGG256 - 108K Gate Antifuse FPGA, 256-FBGA | Microchip

The Microchip Technology A54SX72A-FGG256 (originally Actel/Microsemi) is an SX-A family antifuse FPGA with approximately 108,000 system gates, 6,036 logic cells, and up to 203 user I/O, housed in a 256-ball fine-pitch BGA (FBGA-256) package operating from a single 2.5V supply. An antifuse FPGA is a type of field-programmable gate array whose interconnects are permanently configured at power-up programming time by blowing antifuse elements. Unlike SRAM-based FPGAs, antifuse devices are nonvolatile and reprogrammable-free: the configuration is fixed, which eliminates configuration PROMs, shortens boot time, and improves design security because no bitstream is stored externally. Within the programmable logic hierarchy, the A54SX72A sits at the top of the SX-A family (Actel eXtended architecture), above the A54SX32A and A54SX16A. Key features include 72,000 typical usable gates (108,000 system gates), a maximum toggle rate of approximately 217 MHz, 0.25 um CMOS antifuse technology, and single-chip integration that removes external configuration memory. The device provides dedicated quadrant clock resources (CLKA, CLKB, and QCLK networks) plus hard-wired global clocks for low-skew clocking, as documented in the Microchip SX-A family datasheet. Architecturally, the SX-A fabric is built from combinational and sequential logic modules (C-cells and R-cells) interconnected through a metal-to-metal antifuse routing fabric. This yields low interconnect capacitance, which translates to lower dynamic power and competitive speed for glue logic, bus bridging, and state-machine-heavy designs. The 2.5V core with tolerant I/O structures supports legacy board voltages common in industrial and defense systems. Typical applications include obsolescence-mitigation for legacy Actel designs, industrial automation control, mil-aerospace program logic (the M suffix variant offers military temperature screening), telecommunications backplane bridging, and single-chip integration of multiple discrete logic devices (74-series replacement) for cost and board-space savings. Design consideration: because antifuse programming is one-time, designers must fully validate the design in simulation and, where possible, prototype using the pin-compatible RTSX-S rad-tolerant equivalents in compatible packages before committing production devices.

The antifuse fabric delivers ASIC-like speeds (up to 217 MHz) with very low static power and inherently secure bitstream storage, making it attractive for designs where configuration integrity matters. Architecturally, the SX-A fabric combines Combinatorial Modules and Sequential Modules in a sea-of-modules layout, with high-speed routing resources and dedicated global/quadrant clocking. The 0.25 um process supports 2.5 V operation while maintaining voltage-tolerant I/Os for mixed-voltage board environments. Typical applications include industrial control, communications and networking glue logic integration, aerospace/defense secure designs, and single-chip integration of multiple discrete logic devices to reduce board area and bill-of-material cost.

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.

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.

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 - 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.

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.

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.

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

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.
