AD974AR - 4-Channel 16-Bit 200kSPS ADC | Analog Devices
The Analog Devices AD974AR is a 4-channel, 16-bit, 200 kSPS data acquisition system with a serial interface, housed in a 28-pin SOIC package. It operates from a single 5 V supply and integrates a four-channel input multiplexer, a successive-approximation switched-capacitor ADC, a 2.5 V internal reference, and a high-speed serial interface. Supported analog input ranges include 0 V to +4 V, 0 V to +5 V, and ±10 V. A data acquisition system combines analog signal conditioning, multiplexing, sampling, quantization, and digital conversion into one integrated device. The AD974AR belongs to the ADC family within data-converter and signal-processing semiconductors. Its four-channel multiplexer reduces the need for separate analog switches when several sensors or measurement nodes must be digitized with one converter. The main features are 16-bit resolution, 200 kSPS conversion throughput, four analog input channels, a 2.5 V internal reference, and a single 5 V supply. A power-down mode reduces consumption when acquisition is not required. The serial interface allows converted samples to be transferred efficiently to a digital controller, while the successive-approximation switched-capacitor architecture supports a practical balance among speed, resolution, power, and implementation complexity. The AD974AR can accommodate 0 V to +4 V, 0 V to +5 V, or ±10 V analog input ranges. These ranges make the converter applicable to unipolar industrial measurements, positive voltage sensing, and bipolar instrumentation. The exact input bandwidth, acquisition time, conversion timing, output logic levels, reference accuracy, and operating-temperature limits are not supplied in the verified excerpts and must be confirmed in the manufacturer datasheet before design release. Typical uses include industrial process monitoring, multichannel sensor acquisition, laboratory instrumentation, control systems, and embedded measurement platforms. In each case, the four-channel multiplexer is valuable when multiple signals must share one ADC. Designers should account for source impedance, sampling-charge requirements, serial-interface timing, analog grounding, and the selected input range rather than treating the converter as a direct voltage-measurement block. For reliable operation, place input and reference components close to their associated pins, provide a clean 5 V supply, and route high-speed serial signals away from sensitive analog inputs. Confirm pin functions, package details, acquisition timing, and electrical limits against the official AD974 datasheet. This page combines the verified product description, distributor availability information, package identity, and engineering guidance for legacy or redesign scenarios.
AD974ARS - 4-Channel 16-Bit 200 kSPS ADC | Analog Devices
Analog Devices AD974ARS is a four-channel, 16-bit, 200 kSPS data acquisition system with a serial interface in a 28-pin SSOP package. It combines an input multiplexer, a high-speed successive-approximation switched-capacitor ADC, and an internal +2.5 V reference. The device operates from a single +5 V supply and supports 0 V to +4 V, 0 V to +5 V, or ±10 V analog input ranges. An ADC is an analog-to-digital converter, a data acquisition component that converts continuous analog voltage signals into digital values for processing, measurement, or transmission. In the AD974, the four-channel multiplexer sits ahead of the 16-bit sampling ADC, allowing one converter core to service four single-ended analog inputs. This ADC belongs to the data converter and data acquisition IC hierarchy rather than the broad category of general-purpose analog or digital semiconductors. The primary specifications are a 16-bit conversion resolution, 200 kSPS throughput, four single-ended input channels, and operation from one +5 V supply. The integrated reference is +2.5 V and may be selected as either an internal or external reference. Additional power-management features include a power-down mode, while the on-chip clock reduces the need for external timing circuitry. Maximum power dissipation is listed as 120 mW. Internally, the AD974 uses a successive-approximation, switched-capacitor conversion architecture. The input multiplexer routes one of four single-ended channels to the ADC core, while the sampling system establishes the voltage to be converted. Its serial interface provides a compact connection to a controller, DSP, or embedded processor. The supplied range of 4.75 V to 5.25 V accommodates regulated +5 V system rails while providing defined operating limits. Typical uses include industrial process monitoring, laboratory data logging, multichannel instrumentation, embedded measurement systems, and control equipment. It is especially relevant where four analog inputs must be digitized through a shared 16-bit converter rather than through four separate ADC packages. For lower-throughput acquisition, the multiplexer also reduces conversion contention between channels by sharing the ADC core. A key design consideration is the input-range configuration. The circuit must present only signals within the selected 0 V to +4 V, 0 V to +5 V, or ±10 V range, and the interface and reference arrangement must follow the manufacturer datasheet. Designers should also budget decoupling around the single +5 V supply and account for the 120 mW maximum power dissipation when choosing PCB copper area and the surrounding thermal environment. This product record combines manufacturer and distributor information, verified alternatives, package details, pricing, and application-focused engineering guidance. It is intended to make AD974ARS selection, sourcing, and design-in decisions faster while clearly identifying parameters that require confirmation against the manufacturer datasheet.
AD974ARZ - 16-Bit 200 kSPS 4-Channel ADC | Analog Devices
The Analog Devices AD974ARZ is a 4-channel, 16-bit, 200 kSPS data acquisition system with a serial interface, an input multiplexer, a successive-approximation switched-capacitor ADC, and a 2.5 V internal reference in a 28-pin SOIC package. It operates from a single 5 V supply and supports 0 V to 4 V, 0 V to 5 V, and ±10 V analog input ranges. An ADC is an analog-to-digital converter, a semiconductor that converts continuous voltage signals into numeric data for processing, measurement, or transmission. The AD974 combines a four-channel multiplexer and a 16-bit sampling ADC in one device, making it a data acquisition system rather than a standalone converter. Its serial interface reduces the number of interconnects compared with a parallel converter while preserving the resolution needed for precision measurements. The AD974ARZ combines four single-ended analog input channels, a 200 kSPS maximum sampling rate, 16-bit resolution, and a 2.5 V internal reference. A single 5 V supply simplifies system power design. The device also provides a power-down mode, allowing its power consumption to be reduced when conversions are not required. These features suit multichannel industrial instrumentation, process control, sensor acquisition, laboratory measurement, and embedded data logging. Internally, the four-channel input multiplexer routes the selected input to a high-speed switched-capacitor successive-approximation ADC. Conversion results are transferred through the serial interface. The architecture combines channel selection, conversion, and reference functions in a single IC, reducing the component count required for a multi-input measurement subsystem. Selection of the analog input range is handled by the device architecture rather than requiring four independent converter packages. The AD974ARZ is appropriate when several analog sources must be digitized through one compact, low-power interface. It can be used in industrial process monitoring, factory automation, medical instrumentation, portable measurement equipment, and test systems. Its 16-bit resolution supports detailed signal representation, while the 200 kSPS throughput provides enough conversion bandwidth for many slowly varying or multiplexed measurements. System-level signal conditioning, grounding, and reference requirements still depend on the source impedance and measurement accuracy target. For layout, place input and reference-related components close to their associated pins and preserve a quiet return path around the analog inputs. Because the converter uses switched-capacitor internal nodes, stable reference and supply bypassing are important. A multilayer board with a solid ground plane is generally preferable to relying on long analog traces. Designers must also verify acquisition timing, serial-interface timing, input settling, and the selected voltage range against the complete acquisition cycle. This page combines verified manufacturer information, distributor listings, same-family package comparisons, and practical design guidance. It also distinguishes confirmed drop-in evidence from package variants and clearly identifies missing electrical details rather than estimating unverified specifications.

The supported analog input ranges are 0 V to +4 V, 0 V to +5 V, and ±10 V. An ADC converts continuously varying analog signals into numeric values for measurement, control, or signal processing. The AD974BN combines four single-ended analog inputs with a common 16-bit conversion engine, making it useful when several sensors or voltage signals must be sampled by a compact system. Its serial interface reduces the number of parallel data lines needed on the PCB and supports communication with a digital controller. The converter provides 16-bit nominal resolution and 200 kSPS throughput. These figures define the balance between measurement detail and acquisition speed: the device samples up to 200,000 times per second while representing each selected channel with 16-bit digital data. The integrated reference is +2.5 V, and the system operates from a single +5 V supply. A power-down mode is also included for applications that need to reduce consumption when conversion is not required. The AD974 architecture uses a four-channel input multiplexer and a successive-approximation switched-capacitor conversion process. The input multiplexer selects one of four single-ended analog channels for conversion, while the serial interface transfers conversion results. The integrated 2.5 V reference provides a defined internal reference option, and the datasheet states that the device supports either external or internal reference selection. Typical applications include industrial process monitoring, sensor signal acquisition, laboratory instrumentation, communications equipment, and embedded measurement systems. The four-channel structure is useful when monitoring multiple voltages sequentially, while the 200 kSPS rate supports measurements where moderate-to-high sampling throughput is needed without requiring a parallel ADC output interface. When designing around the AD974BN, preserve adequate analog and digital return paths, place input-conditioning components close to the relevant pins, and account for the selected input range when defining signal scaling. The serial interface timing and power-down behavior should be checked against the controller requirements in the Analog Devices AD974 datasheet.
AD974BNZ - 4-Channel 16-Bit 200 kSPS ADC | Analog Devices

The serial interface provides the converted result to a digital controller or processor. According to the Analog Devices product page and manufacturer datasheet, the internal +2.5 V reference supports the converter without requiring a separate reference source, while the common +5 V supply simplifies system-level power distribution. Typical uses include four-channel process monitoring, sensor signal acquisition, laboratory measurement systems, industrial data logging, and embedded control equipment. The 0 V to +5 V range is particularly useful for systems whose sensor outputs remain within a unipolar 5 V envelope, while the ±10 V option can simplify interfacing with conventional bipolar industrial signals when the surrounding circuitry provides suitable protection and conditioning. Designers should account for input settling, conversion timing, serial-interface implementation, and the voltage headroom required by each selected range. External filtering or source impedance can affect acquisition accuracy, so the signal source and conditioning network should be evaluated together with the acquisition timing. The available manufacturer information identifies a maximum power dissipation of 120 mW but does not provide a verified thermal-resistance value in the supplied data. This page combines manufacturer specifications, distributor availability, verified package information, drop-in comparison options, and practical acquisition-system guidance. It separates documented performance from unavailable details so engineers can review the AD974BNZ for data acquisition, test, and industrial control designs without relying on unverified replacement claims.

The device accommodates several input ranges, including 0 V to +4 V, 0 V to +5 V, and ±10 V. A power-down mode helps reduce consumption when acquisition is not required, while the serial interface supports integration with digital controllers. The manufacturer describes the AD974 as a low-power data acquisition system, and the verified product information identifies a maximum power dissipation of 120 mW. The AD974 uses a successive-approximation switched-capacitor conversion architecture. This architecture is appropriate for acquisition systems that need deterministic sampling, compact implementation, and direct digital output without a complex high-frequency pipeline. The four-channel multiplexer allows one ADC core to process multiple analog inputs sequentially. The serial interface is useful when the converter is connected to a microcontroller, DSP, programmable controller, or other data-processing device; however, the exact supported clock, framing, and output timing must be confirmed from the manufacturer datasheet before final interface design. Typical applications include industrial process monitoring, laboratory instrumentation, sensor-interface systems, factory automation, medical instrumentation, and embedded measurement platforms. The four-channel structure is useful when several analog sensors or conditioned signals must be scanned through one converter. The 200 kSPS sampling rate supports applications requiring periodic measurement rather than high-bandwidth waveform capture. The 16-bit format provides fine numerical resolution for control loops and measurement systems, while the single +5 V supply simplifies power architecture. Designers should confirm the package pinout, analog input configuration, reference selection, clock requirements, and serial-interface timing from the AD974 datasheet. Input conditioning, filtering, grounding, and protection must be selected for the intended voltage range. The SOIC package also requires attention to thermal dissipation and copper routing, particularly when the converter operates continuously at its maximum sampling rate. This page combines verified Analog Devices product information, distributor listing details, package data, and practical acquisition-system guidance. It distinguishes documented parameters from information that still requires datasheet confirmation, helping engineers evaluate the AD974BR for precision multichannel measurement without relying on unverified specifications.
AD974BRS - 4-Channel 16-Bit 200 kSPS ADC | Analog Devices

It is designed for multichannel measurement systems where several analog signals must be converted through a compact serial interface. An ADC is an analog-to-digital converter, a semiconductor that transforms continuously varying analog voltage into numerical data. Within the broader hierarchy, the AD974BRS is a data acquisition system and sampling ADC, belonging to the ADC/DAC and integrated-circuit categories. Its internal multiplexer reduces the number of physical input channels required from the host processor while retaining independent conversion capability for four single-ended analog inputs. The principal features include 16-bit resolution, 200 kSPS throughput, four single-ended analog inputs, a 5 V single-supply architecture, and both internal and external 2.5 V reference options. The on-chip clock reduces the number of external timing components required in a basic acquisition circuit. Power-down operation can also reduce consumption when the measurement system is not actively sampling, although the complete converter specifications and timing behavior must be checked in the manufacturer datasheet before sequencing external analog switches. The AD974BRS uses a successive-approximation, switched-capacitor conversion architecture. This approach provides a compact ADC core suitable for precision multichannel measurement. Its serial interface reduces the number of data connections required between the converter and a digital controller, but it also makes software timing and clock configuration important. Because all channels share one internal ADC and reference system, calibration considerations and channel-to-channel performance should be evaluated for the intended instrumentation system. Typical uses include industrial process monitoring, laboratory data acquisition, environmental sensing, portable instrumentation, and embedded measurement systems. The four-channel multiplexer is useful when several sensor outputs must be sampled into one controller. The ±10 V input option is particularly relevant for legacy industrial interfaces, while the narrower ranges can be used with appropriately conditioned low-voltage sensors. The 5 V supply requirement also simplifies integration with systems that already operate from a regulated 5 V rail. Designers should preserve the analog input range and reference requirements of each channel, verify acquisition timing against the serial-interface clock, and use source and termination networks that do not distort the sampled signal. External reference and input filtering choices can affect accuracy and settling behavior, so the manufacturer’s recommended application circuit should be treated as the baseline design. This page consolidates the verified manufacturer specifications, distributor sourcing information, package details, application guidance, and same-family replacement information into a design-focused reference for engineers evaluating the AD974BRS.

The device also supports analog input ranges suitable for bipolar instrumentation as well as unipolar sensor signals. The internal architecture uses a four-channel analog multiplexer followed by a high-speed successive-approximation, switched-capacitor sampling ADC. Multiplexing four inputs through one converter provides a practical balance between channel count, conversion throughput, power consumption, and package size. This architecture is appropriate when several sensors share a common sampling rate and data-conversion clock rather than requiring simultaneous independent conversion on every channel. Typical uses include multichannel process monitoring, laboratory data logging, factory automation, sensor-interface modules, and embedded measurement systems. The 200 kSPS rate is suitable for many industrial and instrumentation signals, while the 16-bit format provides 65,536 digital codes across the selected input range. For applications requiring simultaneous sampling, substantially faster conversion, or more input channels, a different ADC architecture should be evaluated. A critical design consideration is the relationship between input amplitude, selected range, source impedance, and acquisition time. The 120 mW maximum power dissipation and single +5 V supply simplify power planning, but analog input conditioning and grounding remain essential for accurate conversion. Protect unused channels and control signals according to the manufacturer datasheet, and verify the complete pinout and signal names before PCB layout. This page consolidates verified manufacturer and distributor information, procurement guidance, application analysis, and the limits of available drop-in replacements. It also distinguishes published AD974 family options from genuine pin-compatible substitutes, helping engineers avoid treating different package variants as drop-in components.

The low-glitch architecture highlighted by the manufacturer is relevant to reducing unwanted transient energy during digital-code transitions, although exact glitch specifications require the complete AD9768 datasheet. Typical circuit use places the converter between an 8-bit digital source and a current-to-voltage or load network. Because the output is current-based, external analog circuitry, impedance matching, and careful grounding strongly influence signal quality. The manufacturer describes operation as a standard DAC or as a two-quadrant multiplying DAC, giving designers flexibility for both ordinary waveform generation and multiplier-style signal paths. When designing a board around the AD9768JQ, verify the exact pinout, supply requirements, input logic levels, output compliance, and timing margins from the AD9768 datasheet. The 18-pin CERDIP package is not interchangeable with a surface-mount DAC without a deliberate PCB redesign. The verified distributor result identifies the package as 18-CERDIP, while other electrical values not present in the supplied data are intentionally not guessed.
AD976ABN - 16-Bit 200kSPS SAR ADC, 5V, 28-PDIP | Analog Devices
The Analog Devices AD976ABN is a 16-bit, 200 kSPS successive-approximation analog-to-digital converter housed in a 28-pin PDIP through-hole package, designed for high-speed, low-power data acquisition on a single 5 V supply. Headline specifications include 200 kSPS throughput (the AD976 without the "A" suffix is 100 kSPS), 100 mW maximum power dissipation, and an internal 2.5 V reference that can be overridden with an external source for ratiometric or precision systems. The part contains a successive-approximation switched-capacitor ADC core with self-calibration logic, an on-chip clock, a high-speed parallel interface, and a choice of internal or external reference operation. What is a SAR ADC? A successive-approximation-register analog-to-digital converter is a sampling converter that uses a binary-search algorithm against an internal DAC and comparator to resolve one bit per clock cycle. SAR ADCs sit at the intersection of precision (16-bit and higher) and moderate speed (tens of kSPS to a few MSPS), outperforming flash and pipelined converters in power efficiency and latency while trading off raw speed. They are widely used in industrial process control, instrumentation, and data-acquisition boards where dc-to-audio bandwidth signals must be digitized without the pipeline delay of a pipelined ADC. Key features include single 5 V supply operation, 100 mW max power dissipation, internal 2.5 V reference (with external override), on-chip clock generator, factory-calibrated linearity (no user calibration required), and a high-speed parallel interface for direct connection to microprocessors, FPGAs, or DSP data buses. Input ranges are configured for unipolar 0-5 V or bipolar ±10 V operation with the proper front-end scaling. The 200 kSPS throughput of the AD976A is double the AD976 100 kSPS rate, making it the preferred choice where the bus and downstream logic can sustain the higher sample rate. Architecturally, the AD976ABN is built on a BiCMOS process that combines bipolar precision devices for the input front-end and reference buffer with CMOS logic for the SAR engine, clock, and digital interface. The switched-capacitor input architecture provides inherent sample-and-hold operation, simplifying front-end driver design. Factory calibration trims integral and differential nonlinearity to datasheet limits, removing the iterative software-calibration routine required by many older 16-bit SAR parts and accelerating design-in. Typical applications include industrial process control front ends, multi-channel data-acquisition boards, weigh-scale and strain-gauge instrumentation, motor-control current-sense digitizers, and portable test instruments that need a proven 16-bit ADC on a single 5 V rail. The high throughput and parallel interface make it well suited to closed-loop control where deterministic conversion latency is essential. Design consideration: the input driver amplifier must settle the switched-capacitor input within the acquisition window at full throughput, and the parallel interface traces should be length-matched and series-terminated to avoid digital bus coupling into the analog input. A 100 nF ceramic decoupling cap must be placed within a few millimeters of the supply pins, with bulk capacitance at the regulator output. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement but do not replace the Analog Devices datasheet.

It provides one analog input, a parallel digital interface, selectable internal or external 2.5 V reference, and an on-chip clock. The AD976A is manufactured using Analog Devices' proprietary BiCMOS process, combining high-performance bipolar circuitry with CMOS logic. An ADC converts an analog voltage into a digital value. Within the broader semiconductor hierarchy, the AD976ABR is a data-converter IC and specifically a successive-approximation, or SAR, ADC. SAR converters repeatedly compare the sampled input with a reference and internal bit weights, making them well suited to instrumentation, industrial measurement, communications, and control systems where accurate conversion and predictable parallel data output are required. Key features include 16-bit resolution, 200 kSPS throughput, operation from one 5 V supply, a factory-calibrated analog section, and a high-speed parallel interface. The input range extends to 10 V maximum according to the verified distributor listing, while the converter offers a choice of internal or external 2.5 V reference. Its specified linearity error is 0.0031%, and maximum power dissipation is listed as 100 mW. The AD976A architecture combines a switched-cap ADC core, an accurate reference, and an on-chip clock. Factory calibration and testing address signal-to-noise ratio, total harmonic distortion, offset, gain, and linearity. This integration reduces the number of external timing and reference components required in a 16-bit acquisition circuit while preserving a direct, parallel data path. Typical applications include digital instrumentation, industrial process measurement, communications equipment, data acquisition, control systems, and precision test equipment. The AD976ABR is particularly suitable where a 200 kSPS conversion rate and 16-bit code width must coexist with a conventional 5 V analog supply and parallel digital interface. Designers should follow the manufacturer's pinout and application guidance for input-range, reference, clock, and bypass-capacitor configuration. Input settling, source impedance, analog-noise placement, digital-interface timing, and thermal performance require PCB attention because acquisition accuracy depends on the complete analog signal path rather than conversion resolution alone. This product record consolidates the verified manufacturer and distributor data, distinguishes available family alternatives, and adds practical selection and design guidance that are not presented as a single manufacturer-datasheet summary.
AD976ACR - 16-Bit 200 kSPS SAR ADC | Analog Devices
Analog Devices AD976ACR is a 16-bit successive-approximation analog-to-digital converter with a 200 kSPS throughput rate, single 5 V supply operation, and a 28-lead SOIC package. The device uses a switched-capacitor BiCMOS architecture and provides a parallel data interface for high-speed signal acquisition. It supports either an external reference or an on-chip 2.5 V reference, includes an on-chip clock, and is specified for a maximum power dissipation of 100 mW. A successive-approximation ADC, or SAR ADC, is a type of data-converter IC that determines each digital output code through a sequence of internal comparisons. The AD976ACR belongs to the SAR ADC hierarchy, which sits within analog-to-digital converters and broader data-conversion and semiconductor categories. Its parallel output architecture reduces the external multiplexing burden commonly associated with serial-interface converters, making it suitable for systems that sample waveforms or process digitized measurements at high sample rates. The principal features include 16-bit resolution, a 200 kSPS conversion throughput, single 5 V operation, low power dissipation, and a high-speed parallel interface. The switched-capacitor internal architecture supports the conversion speed specified for the AD976A family. Designers can select an external precision reference or use the internal 2.5 V reference, depending on calibration, drift, and accuracy requirements. An on-chip clock reduces the need for an external timing component when the converter's internal clock is suitable for the application. The AD976 and AD976A family combines a 16-bit switched-capacitor SAR ADC with parallel data outputs in 28-lead DIP, SSOP, and SOIC packages. The AD976A reaches 200 kSPS, while the original AD976 is specified at 100 kSPS. This distinction is important when comparing exact orderable MPNs because a package match alone does not guarantee identical throughput, temperature grade, or lead-finish characteristics. The AD976ACR ordering code specifically denotes the Analog Devices AD976A configuration in a 28-lead SOIC package. Typical applications include industrial instrumentation, communications equipment, data-acquisition systems, medical or laboratory measurement equipment, and embedded DSP signal processing. The 200 kSPS rate is suitable for sampling control and sensor signals when the system requires higher throughput than the 100 kSPS AD976 configuration. The parallel interface can connect directly to suitable digital buses or input stages, although signal conditioning, reference design, and acquisition timing still require careful validation. The main design consideration is preserving the accuracy of a 16-bit conversion while controlling noise, reference stability, and digital-interface timing. Designers should account for the specified 100 mW maximum power dissipation when designing the 5 V supply and board layout. Input and reference routing should minimize noise coupling, while clock and data timing must meet the requirements of the selected parallel interface. The manufacturer datasheet remains the authoritative source for pinout, timing, electrical limits, and application details. This page consolidates the verified manufacturer and distributor information for AD976ACR, distinguishes the 200 kSPS AD976A from the 100 kSPS AD976, records verified sourcing links, and identifies the limited availability of true pin-compatible alternatives. It also provides practical application guidance and transparent data gaps rather than presenting unverified specifications or packaging variants as drop-in replacements.
AD976AN - 16-Bit 100 kSPS ADC | Analog Devices | Signal Acquisition
The Analog Devices AD976AN is a high-speed, low-power 16-bit successive-approximation analog-to-digital converter with a 100 kSPS throughput rate, single 5 V supply operation, and a 28-pin PDIP package. It accepts an analog full-scale input range of ±10 V, includes an internal 2.5 V reference, and provides a high-speed parallel interface. An ADC is a data-acquisition semiconductor that converts an analog voltage into a digital code. The AD976 family uses a switched-capacitor SAR architecture, combining high sampling throughput with factory calibration intended to minimize linearity errors. Its role in the broader hierarchy is ADC > data converter > data-acquisition IC > semiconductor. The AD976A family supports 200 kSPS throughput, while the AD976 supports 100 kSPS throughput. The verified product-page search result identifies the AD976 as a 16-bit converter and confirms the 100 kSPS rate. Other verified features include single 5 V operation, ±10 V input range, internal or external 2.5 V reference selection, an on-chip clock, and a parallel output interface. Because the AD976AN is supplied in a 28-pin PDIP package, it is primarily suited to through-hole legacy, industrial, instrumentation, and educational designs rather than compact surface-mount assemblies. Its parallel bus can require 16 data traces plus control and interface signals, making board routing and input conditioning important design considerations. Typical applications include industrial process measurement, laboratory data-acquisition systems, instrumentation amplifiers, waveform capture, and legacy control equipment. The ±10 V input range can simplify interfacing with suitable sensor and amplifier stages, while the internal reference helps reduce external component count when sufficient accuracy is available. When selecting this part, verify the complete AD976AN datasheet, pinout, timing requirements, reference configuration, input bandwidth, and acquisition timing before layout. This page synthesizes the verified manufacturer information, distributor listing, package data, and design considerations for engineers evaluating the AD976AN.
AD976ANZ - 16-Bit 100kSPS SAR ADC | Analog Devices | 28-PDIP
The Analog Devices AD976ANZ is a 16-bit, 100 kSPS successive-approximation-register (SAR) analog-to-digital converter housed in a 28-pin PDIP (N-28) through-hole package, operating from a single 5 V supply. The device delivers 16-bit resolution with a single-ended analog input and a parallel digital interface, drawing approximately 100 mW of maximum power. The BiCMOS switched-capacitor architecture provides a wide input range and excellent AC/DC performance for industrial data-acquisition systems. An SAR ADC is a successive-approximation-register analog-to-digital converter that uses a binary search algorithm against an internal precision DAC to resolve N bits in N clock steps. SAR ADCs are a subtype of Nyquist-rate data converters that sit within the broader data acquisition IC category, which itself is part of the signal-chain and mixed-signal semiconductor hierarchy. Compared to delta-sigma ADCs, SAR converters offer lower latency, deterministic throughput, and no pipeline delay, which makes them preferable for multiplexed multi-channel acquisition and event-triggered sampling. Key features include 100 kSPS guaranteed throughput, single 5 V supply operation, internal 2.5 V reference (with external reference override), and analog input range of ±10 V when using proper input scaling. The AD976ANZ integrates a high-speed parallel interface that directly connects to 16-bit microprocessors and DSPs, and includes flexible analog input conditioning for unipolar (0 V to 5 V or 0 V to 10 V) and bipolar (±5 V or ±10 V) ranges using a single +5 V supply. Throughput latency is negligible, which is critical for closed-loop control and multiplexed systems. From an architecture standpoint, the AD976 and its higher-speed sibling AD976A share Analog Devices' proprietary BiCMOS process, combining bipolar precision devices with CMOS logic for low power and high accuracy. The device is offered in three pin-compatible packages - skinny 28-pin PDIP (this AD976ANZ variant), 28-pin SOIC, and 28-pin SSOP - giving designers flexibility for prototyping, volume production, or surface-mount reflow. Typical applications include industrial process control, multi-channel data acquisition boards, instrumentation front-ends, and medical monitoring equipment. The 100 kSPS throughput is well matched to multiplexed analog input cards that sequentially sample multiple 12- or 16-bit channels. The wide analog input range also suits vibration, strain, and pressure measurement systems where high common-mode rejection is needed. When designing with the AD976ANZ, place the analog input decoupling capacitor as close to the AIN pin as possible, maintain solid ground stitching between the analog and digital ground planes, and ensure the REFCAP pin is properly buffered with a 2.2 µF ceramic capacitor to minimize conversion noise. This page synthesizes distributor pricing, drop-in compatible variants, and practical PCB layout guidance not found in the manufacturer datasheet - including a same-package, same-pinout comparison against the AD976A 200 kSPS upgrade path.
AD976AR - 16-Bit 100 kSPS SAR ADC | Analog Devices
The Analog Devices AD976AR is a 16-bit successive-approximation analog-to-digital converter with a 100 kSPS throughput rate, one single-ended input, and a 28-lead SOIC package. It operates from one 5 V supply, supports internal or external reference selection, includes an on-chip clock, and provides a high-speed parallel output interface. These characteristics make it a compact mixed-signal conversion component for industrial control, instrumentation, signal acquisition, communications, and embedded measurement systems. An ADC is an analog-to-digital converter, a semiconductor that transforms a continuous analog voltage into a numeric code. The AD976AR belongs to the successive-approximation, or SAR, ADC family. Unlike a pipeline ADC, a SAR ADC compares the sampled input against successive trial thresholds during a sequence of conversion cycles. Its sampled input, bit resolution, throughput, reference method, and parallel interface determine the balance between measurement speed, signal detail, circuit complexity, and downstream data handling. The AD976 family combines several conversion functions in one device. Its 16-bit resolution provides 65,536 possible code levels, while the AD976 version in this MPN operates at 100 kSPS. The AD976A family member reaches 200 kSPS, but it is not an interchangeable speed upgrade unless its complete pinout, timing, reference, and interface requirements are independently verified. Operation from a single 5 V supply simplifies system power planning, while internal or external reference choices support different accuracy and calibration strategies. The converter uses a switched-capperitor SAR architecture implemented with Analog Devices BiCMOS technology, combining bipolar and CMOS devices. Its internal 2.5 V reference can provide a self-contained conversion solution, while the external-reference option permits board-level reference selection. The high-speed parallel interface presents converted codes directly across digital output pins, making it suitable for logic devices, DSPs, microprocessors, or data latches capable of capturing the required output timing. Typical uses include closed-loop industrial process monitoring, low-frequency sensor digitization, laboratory measurement equipment, communications receivers, and embedded control systems. The 100 kSPS rate is appropriate for signals that do not require video-bandwidth conversion, while the 16-bit code width can preserve fine amplitude detail. Designers should verify input range, acquisition time, digital timing, output coding, reference requirements, and electrical limits against the manufacturer documentation before fixing the system architecture. A key design consideration is the relationship between sampling, acquisition, conversion, and output timing. The system must provide a stable input during the sample-and-hold interval and capture the parallel output according to the converter timing. The selected reference must satisfy the required accuracy, noise, temperature, and startup behavior, while external decoupling and grounding should follow the datasheet recommendations. This product record combines the verified manufacturer and distributor details with application guidance, design cautions, and a transparent distinction between verified specifications and unavailable data. It is intended to support initial engineering selection while avoiding unsupported assumptions about parameters, compliance, lifecycle guarantees, or replacement parts.
AD976ARZ - 16-Bit 100 kSPS SAR ADC | Analog Devices
The Analog Devices AD976ARZ is a single-channel, 16-bit successive-approximation analog-to-digital converter with a sampling rate of 100 kSPS, operating from a single 5 V supply in a 28-pin SOIC package. It accepts a single-ended input and uses a high-speed parallel interface, while an integrated 2.5 V reference and on-chip clock reduce the external circuitry required for a complete conversion system. The converter is fabricated on a BiCMOS process that combines high-performance bipolar devices with CMOS transistors. An ADC is an analog-to-digital converter, a semiconductor that samples a continuous voltage and converts it into a numeric value for processing, storage, or transmission. The AD976 belongs to the successive-approximation ADC, or SAR ADC, family within the broader ADC and data-converter hierarchy. SAR converters repeatedly compare the sampled input against a generated reference and progressively determine each output bit. Their architecture is widely used where moderate conversion speed, accurate results, and a compact parallel interface are more important than very high sampling rates. The AD976 provides a 16-bit conversion resolution and a throughput rate of 100 kSPS. It operates from a single 5 V supply, accepts a single-ended analog input, and offers a parallel data interface. An internal 2.5 V reference and on-chip clock are integrated into the converter. According to Analog Devices, the AD976 and AD976A are factory calibrated and fully tested for signal-to-noise ratio and total harmonic distortion as well as offset, gain, and linearity characteristics. Maximum power dissipation is specified at 100 mW, allowing the converter to fit industrial, instrumentation, communications, and embedded-control systems without requiring a high-power thermal design. The AD976A member of the family reaches 200 kSPS, but the AD976ARZ specifically operates at 100 kSPS. This distinction is important when selecting a replacement because throughput is one of the key parameters used to determine drop-in compatibility. Typical uses include precision process measurement, industrial transducer acquisition, laboratory instrumentation, communications equipment, and embedded systems that need a parallel 16-bit conversion result. The 100 kSPS throughput supports waveforms and control loops that require substantially more resolution than a conventional 8-bit converter while avoiding the complexity and power requirements of a much faster high-speed ADC. When designing around the AD976ARZ, verify the analog input range, reference configuration, acquisition timing, and digital interface mapping against the manufacturer datasheet. Input conditioning should limit noise and establish a signal range compatible with the converter. PCB layout should keep the analog input path short and isolate parallel data routing from sensitive input nodes to reduce conversion error and digital coupling. This page consolidates the verified manufacturer and distributor information for AD976ARZ, including pricing, technical distinctions, package constraints, and selection guidance that are more useful for an engineering decision than a distributor title alone. It also distinguishes the confirmed 28-pin SOIC AD976AR option from faster AD976A and AD976B variants that cannot be treated as drop-in equivalents.
AD976BN - 16-Bit 100kSPS ADC | Analog Devices | 28-PDIP
The Analog Devices AD976BN is a 16-bit, 100 kSPS successive-approximation register (SAR) analog-to-digital converter operating from a single 5 V supply, housed in a 28-pin PDIP (skinny DIP) through-hole package. The part integrates a switched-capacitor SAR ADC core, an internal 2.5 V reference (selectable as external via the REF pin), and a high-speed parallel data interface with byte- and word-mode access, plus a single-ended analog input with input range up to ±10 V (with proper input scaling) or 0-4 V unipolar in default configuration. Background. A SAR ADC (successive-approximation register analog-to-digital converter) is a class of Nyquist-rate data converter that resolves one bit per internal clock cycle by comparing the sampled input against a binary-weighted internal DAC. SAR ADCs are valued for their deterministic latency, no-pipeline-delay sampling, and excellent DC linearity, making them a workhorse for industrial process control, instrumentation, and precision data acquisition. The AD976 family sits at the upper end of ADI's legacy 16-bit SAR portfolio and uses BiCMOS process technology that combines low-noise CMOS analog with bipolar drive for the internal reference and high-speed parallel bus. Key features include 100 kSPS throughput (the AD976A variant in the same family runs at 200 kSPS), 100 mW typical power dissipation from a single +5 V analog supply, internal 2.5 V reference with external override, a high-speed parallel interface configurable as 8-bit (byte mode) or 16-bit (word mode), on-chip clock, and selectable bipolar/unipolar analog input ranges. The bipolar BiCMOS process delivers low analog input current and excellent integral non-linearity (INL), suitable for precision measurement. Typical applications include industrial process control and instrumentation, data acquisition boards for legacy backplanes, medical instrumentation interfaces, and bench-top test equipment where deterministic SAR latency is preferred over pipelined ADCs. The single 5 V supply and parallel interface make it particularly well-suited for retrofits of older +5 V-only designs. When designing with this part, ensure the analog input is buffered by a low-impedance, low-noise op-amp (such as the AD845 or AD797 family) because the SAR's switched-capacitor input presents a transient kick-back at every conversion cycle. Decouple AVDD and DVDD separately, and place a 10 µF tantalum in parallel with a 0.1 µF ceramic adjacent to each supply pin. This page synthesizes current distributor pricing, drop-in 28-PDIP alternatives, application notes and PCB layout guidance not collected in any single source, so an engineer evaluating the AD976BN can make a sourcing and design decision in one pass.
AD976BNZ - 16-Bit 100 kSPS SAR ADC | Analog Devices
The Analog Devices AD976BNZ is a 16-bit successive-approximation analog-to-digital converter with a 100 kSPS throughput rate, a single 5 V supply, parallel I/O, and a 28-pin through-hole DIP package. Its specified supply operating range is 4.75 V to 5.25 V, and the AD976 family also supports a 200 kSPS AD976A counterpart. An ADC is an interface IC that converts an analog voltage into a digital code for processing, storage, transmission, or control. The AD976 belongs to the successive-approximation ADC family, which repeatedly compares the input against a generated reference to resolve a digital result. This architecture sits within the broader ADC and data-converter hierarchy and is commonly used where moderate speed, resolution, and parallel data output are practical. Key features include 16-bit resolution, 100 kSPS throughput, one analog input, and a 5 V single-supply operating range. The manufacturer describes the converter as a high-speed, low-power switched-capacitor ADC. Parallel output reduces the need for a serial interface, while the 28-pin DIP package supports conventional through-hole assembly and prototyping. The industrial temperature grade makes the part relevant to industrial instrumentation, although a numerical temperature range is not present in the supplied data. The AD976 uses a successive-approximation, switched-capacitor architecture. Its parallel interface can connect directly to suitable digital acquisition hardware or an embedded system with appropriate voltage levels and timing. The manufacturer datasheet also describes 200 ohm and 33.2 kilohm external resistors used to compensate the internal offset and gain adjustment, allowing calibration with a single supply. These details distinguish calibration behavior from the ADC's core conversion specifications. Typical uses include industrial process-control instrumentation, laboratory data acquisition, digital panel meters, waveform measurement, and embedded control systems. The 16-bit resolution supports fine-grained representation of a measured voltage, while the 100 kSPS rate is appropriate for slow-changing or bandwidth-limited analog signals. It is not positioned as a high-frequency waveform converter compared with devices operating at hundreds of kilomegasamples per second or faster. Designers should preserve the specified 4.75 V to 5.25 V supply range, provide suitable reference and decoupling arrangements, and verify that the parallel interface timing is compatible with the receiving logic. Because only verified package, resolution, throughput, supply, architecture, and related-family information was available here, input range, SNR, INL, DNL, clock requirements, and absolute maximum ratings should be confirmed in the manufacturer datasheet before release to production. This page consolidates verified AD976 family specifications, current distributor sourcing, package details, and practical replacement guidance. It also separates confirmed AD976BNZ attributes from parameters that still require direct verification, helping engineers compare procurement choices without presenting unsupported electrical values as established facts.
AD976BR - 16-Bit 100 kSPS ADC | Analog Devices
The Analog Devices AD976BR is a 16-bit successive-approximation analog-to-digital converter with a 100 kSPS throughput rate, a single 5 V supply, and a 28-lead SOIC package. It provides one analog input, an internal 2.5 V reference option, a high-speed parallel interface, and an on-chip clock. The AD976 family is positioned for precision signal acquisition where 16-bit resolution and moderate conversion speed are required. The AD976A, in contrast, is identified in the manufacturer material as the 200 kSPS member of the same AD976/AD976A family. An ADC is an analog-to-digital converter, a semiconductor that transforms a continuously varying analog voltage into a numeric code. Within the broader hierarchy, an ADC is a data-acquisition and signal-conversion IC; a successive-approximation ADC performs conversion by comparing the input voltage with an internally generated DAC and successive trial bit decisions. This architecture provides a practical balance between conversion throughput, resolution, power consumption, and implementation complexity for industrial, communications, instrumentation, and embedded control systems. Key verified features of the AD976BR include 16-bit resolution, 100 kSPS throughput, one analog input, single 5 V operation, selectable external or internal 2.5 V reference, an on-chip clock, a high-speed parallel interface, and a maximum input range stated in the retrieved data as 100 mV. The manufacturer material also identifies low-power operation and both external and internal reference choices. The 28-lead SOIC package is confirmed by distributor and comparison listings. The AD976BR uses a switched-capacitor successive-approximation architecture. During conversion, the internal sample-and-hold network captures the input, while the comparison and DAC network determine successive code bits. Because the converter uses a parallel interface, the host system must capture or latch the 16-bit result and handle the associated digital timing. The AD976BR is therefore most useful when moderate sampling rates are sufficient but software-based or low-speed serial conversion would be inadequate. Typical applications include industrial process monitoring, sensor-interface systems, communications equipment, data-acquisition instruments, and embedded measurement platforms. The 100 kSPS rate is suitable for acquiring slowly changing or burst-sampled signals, while the 16-bit code width supports precision measurement and control. The single-supply architecture can simplify system design when a 5 V analog rail is already available, although input conditioning, reference stability, digital grounding, and timing remain important engineering concerns. When designing around the AD976BR, place input, reference, and decoupling connections according to the manufacturer datasheet and keep the analog input path away from high-current digital switching nodes. Check acquisition time, input impedance, source drive capability, reference configuration, and the host parallel-interface timing. Do not substitute a converter merely because its resolution matches; pin compatibility, sampling architecture, input range, reference behavior, and acquisition timing must also be verified. This page combines verified Analog Devices product information, distributor package and interface details, application guidance, comparison fields, and design notes. It also explicitly identifies where pricing, pinout, lifecycle, or replacement data are not present in the supplied web evidence.
AD976BRZ - 16-Bit 100 kSPS SAR ADC | Analog Devices
The Analog Devices AD976BRZ is a 16-bit, single-channel successive-approximation analog-to-digital converter with a 100 kSPS sampling rate, operated from a single 5 V supply and housed in a 28-pin SOIC package. Its principal operating characteristics are 16-bit resolution, 100 kSPS throughput, a 4.75 V to 5.25 V analog supply range, and a 100 mW maximum power dissipation. An ADC is a data-acquisition interface that converts a continuously varying analog voltage into a numeric value for processing, storage, or transmission. The AD976 belongs to the successive-approximation ADC hierarchy within mixed-signal semiconductors. It uses a switched-capacitor internal architecture, an internal 2.5 V reference, and a high-speed parallel digital interface to provide deterministic conversion results in instrumentation and signal-processing systems. Key features include 16-bit resolution, a 100 kSPS throughput rate, single-ended analog input, a 5 V analog supply, and parallel data output. The internal reference reduces the number of external precision components required for basic converter operation. The manufacturer datasheet also describes external offset and gain calibration using 200 ohm and 33.2 kilohm resistors, allowing system-level calibration when operating from a single supply. The AD976 uses a successive-approximation, switched-capper architecture implemented with Analog Devices proprietary BiCMOS technology. The BiCMOS process combines high-performance bipolar devices with CMOS transistors, supporting the internal reference, sampling network, and parallel interface. The AD976A family shares this architecture but offers a 200 kSPS throughput rate, so it is not a parameter-equivalent drop-in choice for a design specifically requiring the 100 kSPS AD976. Typical uses include industrial measurement, instrumentation, signal acquisition, data logging, and embedded control systems that accept single-ended analog inputs. It is especially relevant where a 16-bit conversion result, parallel data bus, and moderate sampling rate are more useful than the maximum throughput of a high-speed flash or pipeline converter. Designers should use a suitable acquisition, reference, and decoupling network around the converter and account for analog input settling time before sampling. Because the AD976BRZ uses a 28-pin SOIC package, its footprint is relatively large compared with modern fine-pitch mixed-signal packages. The verified source set does not expose the complete pin names, so this page does not reproduce an unverified pin assignment. This page combines verified manufacturer specifications, distributor availability, application guidance, and procurement information. It also distinguishes the 100 kSPS AD976BRZ from the faster AD976A, preventing a speed-related substitution from being presented as a true drop-in replacement.
AD976CN - 16-Bit 100 kSPS BiCMOS ADC | Analog Devices
The Analog Devices AD976CN is a 16-bit, 100 kSPS successive-approximation BiCMOS analog-to-digital converter operating from a single 5 V supply and housed in a 28-lead ceramic DIP package. The converter accepts one single-ended input and uses a high-speed parallel interface for direct digital data transfer. Its family supports selectable external or internal 2.5 V references and includes an on-chip clock. An ADC is an analog-to-digital converter, a data-acquisition IC that transforms a continuously varying voltage into a numeric code for processing, storage, or control. The AD976 belongs to the successive-approximation ADC hierarchy within integrated circuits and data-conversion semiconductors. At 100 kSPS and 16-bit resolution, it balances conversion speed with precision while preserving a straightforward parallel-output architecture. The AD976CN's headline parameters are its 16-bit resolution, 100 kSPS conversion throughput, and single 5 V supply operation. According to the Analog Devices AD976 product page, the closely related AD976A reaches 200 kSPS, while the AD976 is specifically identified as the 100 kSPS member. The family also supports external or internal 2.5 V references, a feature that gives designers flexibility in establishing full-scale conversion range. The BiCMOS implementation combines bipolar and CMOS process characteristics to support precision sampling, comparison, and digital output functions. Maximum power dissipation is listed as 100 mW, while typical power-supply current is specified at 14 mA under stated conditions. The converter uses a parallel data interface, which can simplify connection to older digital buses and dedicated data-acquisition controllers when timing and bus-width constraints are managed correctly. Typical uses include industrial process monitoring, instrumentation, digital measurement equipment, waveform acquisition, and embedded control systems. Its single-ended input architecture is useful when the source can be referenced and scaled to the selected input range. The internal or external 2.5 V reference choice also makes the ADC suitable for laboratory and industrial systems where traceability or system-level reference partitioning affects measurement accuracy. When designing around the AD976CN, preserve the manufacturer's recommended analog and digital grounding and decoupling arrangements, and account for acquisition, conversion, and output-update timing at the system level. The 28-lead DIP package is less common in new high-density assemblies, so designers should verify connector availability and assembly process requirements before committing the footprint. Because the verified data identifies AD976CN as obsolete or EOL, lifecycle planning and sourcing risk are significant selection considerations. This page consolidates the verified manufacturer specifications, lifecycle information, sourcing context, and design implications for AD976CN. It also distinguishes verified facts from parameters that remain unavailable in the supplied data, helping engineers evaluate legacy replacements without assuming unverified electrical or pin-level compatibility.
AD976CNZ - 16-Bit 100kSPS BiCMOS ADC | Analog Devices
The Analog Devices AD976CNZ is a 16-bit, 100 kSPS successive-approximation analog-to-digital converter in a 28-pin PDIP (N-28) through-hole package. It operates from a single 5 V supply (4.75 V to 5.25 V), accepts input ranges of ±10 V, 0-10 V, and 0-4 V, and delivers 100 mW typical power dissipation, suiting it to industrial instrumentation, data acquisition, and process control front ends. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts a continuous-time, continuous-amplitude analog input into a discrete-time, discrete-amplitude digital codeword. Within the broader signal-chain taxonomy, an ADC belongs to data converters, which sit alongside DACs (digital-to-analog converters) in mixed-signal ICs. Successive-approximation-register (SAR) ADCs use a binary-search algorithm and an internal precision DAC to converge on the input voltage in N clock cycles, achieving high resolution at moderate sampling rates with very low latency and zero pipeline delay. Key features include 16-bit resolution, 100 kSPS throughput, a parallel data interface, single 5 V supply operation, and an internal 2.5 V reference. The device is specified over the -40 °C to +85 °C industrial temperature range, uses a switched-capacitor input architecture, and dissipates only 100 mW maximum. The 28-pin PDIP (N-28) package simplifies prototyping and breadboarding in laboratory and factory-floor applications where socketed through-hole parts are preferred. Architecture-wise, the AD976 employs BiCMOS process technology, combining bipolar precision analog blocks with CMOS logic for the SAR engine and output latches. The BiCMOS integration reduces analog-domain noise while keeping digital control current low, supporting the part's 100 mW dissipation budget at full throughput. An external or internal reference option allows designers to trade absolute accuracy against system cost. Typical applications include industrial process control, multichannel data-acquisition systems, portable instrumentation, and PC/embedded signal-conditioning front ends. The single-5 V supply and parallel interface make it easy to interface to legacy microcontrollers, DSPs, and FPGAs without level translation. When designing with the AD976CNZ, observe the input-common-mode and acquisition-time requirements; an external input buffer amplifier is normally required to drive the switched-capacitor input. Use a low-impedance ground plane and decouple AVCC and DVCC separately to preserve the converter's 16-bit linearity. This page synthesizes distributor pricing, drop-in same-family and cross-brand equivalents, and practical design notes not found in the bare manufacturer datasheet, helping engineers source and qualify the AD976CNZ quickly.
