It operates from a single 4.5V to 5.5V supply and delivers ±1 LSB DNL monotonicity with ±1 LSB INL linearity. The full-scale output current is 2 mA ±20%, set by an external reference voltage, and an internal feedback resistor (RFB) simplifies I-to-V conversion when combined with an external op amp such as the AD8038. A multiplying DAC is a converter whose output is the product of a digital input code and an analog reference voltage, enabling four-quadrant operation when bipolar signals are applied. The AD5545 belongs to the current-output multiplying DAC category, which sits within the broader hierarchy of digital-to-analog converters -> data converters -> mixed-signal ICs -> semiconductor devices. Current-output architectures are favored where the reference must vary with a signal (such as in gain control, attenuators, or automatic test equipment) rather than being a fixed precision voltage. Key features include a 2Q multiplying reference input, 0.5 µs full-scale settling time, and a bipolar output swing of up to ±15 V when used with an external high-voltage op amp.

A multiplying DAC is a converter whose output is the product of a digital code and an analog reference input. This category sits within the broader hierarchy of digital-to-analog converters -> data converters -> mixed-signal ICs -> semiconductors. Multiplying DACs are typically implemented with R-2R ladder networks because the architecture allows the reference input to vary (including AC) without disturbing monotonicity, and is therefore preferred over resistor-string designs when 4-quadrant multiplication, bipolar operation, or wide reference range is required. Key features of the AD5545 include +/-1 LSB DNL (monotonic), +/-1 LSB INL, a 3-wire serial interface (SDI, CLK, CS) compatible with microcontrollers, and an LDAC function that allows simultaneous update of both DAC outputs. The internal reset logic supports power-on preset and dynamic reset at either zero or midscale, configurable via the MSB pin. Input reference voltages are accepted in the range of -12 V to +12 V with a constant nominal input resistance of 5 kohm +/-30%, enabling 4-quadrant multiplication. Internally the AD5545/AD5555 use a matched thin-film R-2R ladder network per channel with CMOS switches steered by the input register, a precision bandgap-based reference input conditioning network, and an LDAC-triggered double-buffered latch architecture. This topology delivers low gain error and excellent DC accuracy while keeping digital feedthrough low. AC reference inputs are also accommodated, making the part suitable for waveform generation and audio gain control. Typical applications include precision instrumentation, automatic test equipment (ATE) level setting, digitally controlled calibration, waveform synthesis, audio gain control, and industrial process control. The wide bipolar output swing and multiplying capability make it especially attractive for four-quadrant signal chains and high-accuracy analog output modules in PLC and data-acquisition systems. When designing with the AD5545, choose a low-offset, low-noise op-amp such as the AD8038 or AD8065 for the I-to-V conversion stage, and lay out the TSSOP footprint with analog/digital ground partitioning. Reference decoupling with 0.1 uF close to the REF pin is recommended, and the LDAC line should be tied high for simultaneous update operation.

Typical uses include industrial process measurement, temperature and pressure instrumentation, laboratory data acquisition, legacy industrial controls, and embedded systems requiring an eight-bit measurement channel. Its extended-temperature specification makes it appropriate for harsh environments when the system must preserve full eight-bit accuracy and avoid missing output codes. Designers should preserve the required supply sequencing and logic-level constraints stated in the manufacturer datasheet. Because the output interface uses multiplexing and three-state outputs, the system must place each output into a valid state only when its associated data is being read. Decoupling, input grounding, and acquisition timing should be evaluated against the approximately 25-microsecond conversion requirement. This page combines converter architecture, temperature-range guidance, application fit, pin-package considerations, and drop-in replacement analysis. It also distinguishes standard, military, and extended-temperature AD570 family options so engineers can select the appropriate package and qualification level for the target system.

The Analog Devices AD571JD is a 10-bit, single-input successive-approximation analog-to-digital converter with an internal voltage reference and clock, packaged in an 18-pin ceramic DIP. It performs conversions in 40 microseconds maximum and provides three-state parallel digital outputs for connection to microprocessors, controllers, and data-acquisition systems. The converter integrates a DAC, voltage reference, clock, comparator, successive-approximation register, and output buffers on one monolithic chip. An ADC converts a time-varying analog voltage into a digital number representing its amplitude. The AD571 belongs to the SAR ADC hierarchy, where an internal DAC produces successive approximation voltages that are compared with the input. Its complete-converter architecture places the reference, clock, and output circuitry together, reducing the number of external components required for basic acquisition systems. The AD571JD provides 10-bit resolution, one analog input channel, and a maximum conversion time of 40 microseconds. Three-state outputs permit multiple converters to share a common data bus when only one device is selected at a time. The monolithic construction supports a compact implementation, while the 18-pin ceramic DIP package facilitates replacement and prototyping in through-hole systems. The AD571 combines a 10-bit DAC, voltage reference, oscillator or clock section, comparator, successive-approximation register, and buffered outputs. According to the manufacturer documentation, the converter is designed for no missing codes over temperature up to +125 degrees Celsius. The parallel interface exposes the conversion result directly rather than using a serial protocol, making the device suitable for processor-controlled instrumentation where interface simplicity is important. Typical uses include industrial process measurement, laboratory data acquisition, digital panel meters, and embedded control systems that sample slowly varying analog signals. Its integrated reference and clock also suit educational or prototype systems where a complete standalone converter is more useful than a bare ADC core. The parallel output can connect to suitable data buses when the host processor provides the required control signals and output enable timing. Designers should verify the analog input range, reference accuracy, acquisition timing, and output logic levels against the complete manufacturer datasheet before layout. Because this is a ceramic DIP rather than a surface-mount device, board footprint and mechanical clearance must match the specified 18-pin package exactly. Replacement should also account for temperature grade and screening options rather than relying only on the 10-bit resolution and 40-microsecond conversion-speed labels. This page consolidates verified manufacturer and distributor information, package-level replacement guidance, and practical selection considerations that help distinguish a true drop-in ceramic-DIP replacement from merely similar ADC products.

Its primary characteristics are 10-bit resolution, commercial temperature grade, through-hole construction, and an 18-terminal rectangular DIP package. An ADC is an interface component that converts an analog voltage into a digital number for processing, measurement, display, or control. The AD571 belongs to the successive-approximation, or SAR, ADC family. In this architecture, an internal DAC generates successive trial voltages, the comparator evaluates each trial against the input, and the successive-approximation register records the conversion result. The AD571 integrates the supporting conversion elements on one chip, reducing the number of external components required for a complete conversion channel. The AD571's 10-bit conversion resolution provides 1,024 distinguishable digital codes across the converter's analog input range. This resolution is suitable for instrumentation and control systems that need moderate rather than high-resolution digital measurement. Its integrated reference, clock, comparator, DAC, register, and output buffers establish a self-contained conversion architecture, while the parallel output interface provides direct access to the converted code. The AD571KD/+ is identified as a commercial-grade, through-hole device in an 18-pin SBCDIP package.

AD571SD

AD571SD - 10-Bit SAR ADC with Reference | Analog Devices

The Analog Devices AD571SD is a 10-bit, single-input successive-approximation analog-to-digital converter integrated with a digital-to-analog converter, voltage reference, clock, comparator, successive-approximation register, and output buffers in an 18-pin SBDIP package. The device operates from a +5 V supply with a -12 V or -15 V analog supply, and it supports standard 0 V to +10 V unipolar or -5 V to +5 V bipolar input ranges. It is not recommended for new designs. A successive-approximation ADC is a data-converter category that compares an unknown analog voltage with successive internally generated reference levels. Each clock cycle resolves one additional bit, allowing a complete conversion to be completed in 10 clock periods. The AD571 integrates this conversion function with its supporting DAC and reference circuitry, reducing the number of external precision components required in conventional instrumentation designs. Key features include 10-bit resolution, one analog input channel, successive-approximation conversion, a complete on-chip reference and clock, parallel digital outputs, and integration of the principal converter blocks on one monolithic chip. The AD571 can be configured for 0 V to +10 V unipolar operation by connecting the bipolar-offset control to digital common, or for -5 V to +5 V bipolar operation by leaving that control open. The converter architecture compares the selected input against a DAC-generated trial voltage and uses a comparator to determine each successive-approximation decision. A 10-bit successive-approximation register retains the conversion result until the next conversion or a clear operation. Its integrated reference establishes the conversion scale, while the clock controls conversion timing and the output buffers provide compatible parallel digital outputs for external counters, processors, or display systems. Typical applications include digital voltmeters, process-control instrumentation, laboratory measurement equipment, industrial data-acquisition systems, and embedded measurement systems that require a parallel-output ADC. In these systems, the AD571 can reduce the need for a discrete reference and DAC, although its legacy interface and lifecycle status make it primarily appropriate for maintenance of existing equipment. Designers should account for the separate +5 V and negative analog supplies, connect analog and digital grounds according to the manufacturer's grounding guidance, and use suitable bypass capacitors at the supply pins. Sampling and clock timing should also be checked against the acquisition system so that acquisition time and conversion time provide sufficient settling before the result is read. This product page combines manufacturer specifications, lifecycle information, package details, application guidance, and verified cross-reference results for engineers maintaining an AD571SD-based design. It also distinguishes confirmed drop-in candidates from alternatives that would require different packages or electrical behavior.

AD572AD

AD572AD - 12-Bit Successive Approximation ADC | Analog Devices

The Analog Devices AD572AD is a complete 12-bit successive-approximation analog-to-digital converter with an internal clock, reference, comparator, and buffer amplifier, housed in a 32-pin through-hole DIP package. The converter supports parallel and serial data transfer, according to product listings, and uses a hybrid integrated-circuit construction that combines MSI digital circuitry with linear monolithic chips. Its high-stability thin-film resistors are actively laser trimmed to improve accuracy, repeatability, and production consistency. An ADC is a data-conversion IC that transforms a continuously varying analog voltage into a digital code for processing, measurement, or control. The AD572 belongs to the ADC hierarchy, where it is more specifically a successive-approximation converter, sometimes called a SAR ADC. Unlike a flash converter, this architecture compares the input against successively refined internal references and therefore supports relatively high resolution with a practical internal circuit arrangement. The AD572AD's principal specifications include 12-bit resolution, differential input capability, parallel and serial output options, and a 32-pin DIP package. Its internal reference and buffer amplifier reduce the number of external signal-conditioning elements required for many measurement systems. Active laser trimming of thin-film resistors helps establish stable conversion characteristics without relying on ordinary uncorrected resistor tolerances. The hybrid construction is significant because it divides the converter into digital and linear functional blocks. The MSI digital section manages conversion sequencing and data output, while the monolithic linear section supports the reference, comparator, and signal-buffer functions. This architecture allows the converter to operate as a largely complete acquisition element rather than requiring a separate clock, reference source, comparator, and input buffer. AD572AD is suited to industrial process measurement, instrumentation, laboratory data acquisition, closed-loop control, and test systems where a 12-bit conversion result and selectable parallel or serial data handling are useful. The through-hole DIP format also suits legacy industrial equipment and prototypes assembled with conventional through-hole insertion methods. Designers should follow the Analog Devices AD572 datasheet for the exact analog input range, conversion timing, logic levels, reference behavior, and recommended decoupling. Because this converter combines an internal reference with analog input conditioning, stable grounding and careful routing of the analog and digital return paths remain important. Review the complete pin description table before assigning board nets or selecting bypass-capacitor locations. This product page consolidates the known resolution, converter architecture, package, interface options, and construction details with practical sourcing, application, comparison, and design guidance. It also distinguishes verified drop-in alternatives from merely similar converters, helping engineers make package and pin-compatibility decisions before committing to a replacement.

AD572BD

AD572BD - 12-Bit SAR ADC | Analog Devices | SBCDIP-32

The Analog Devices AD572BD is a complete 12-bit successive-approximation analog-to-digital converter with parallel and serial interfaces, an internal clock, internal reference, comparator, and buffer amplifier, housed in a 32-pin SBCDIP package. The converter combines digital and linear monolithic elements with active laser trimming of high-stability thin-film resistors, providing a compact, complete solution for converting analog signals into 12-bit digital data. An ADC is an interface component that translates a continuously varying voltage into a numeric representation for processing by a microprocessor, controller, FPGA, or other digital system. The AD572 belongs to the data-converter hierarchy and uses the successive-approximation, or SAR, method. In this architecture, an internal successive-approximation register compares the input against a generated reference voltage, progressively refining the result until the converted code corresponds to the analog input. The AD572 integrates functions that would otherwise require separate clock, reference, comparator, and input-buffer circuitry. Its 12-bit resolution provides 4096 possible digital output codes. Parallel output supports direct connection to digital buses, while serial output reduces the number of signal interconnects when board space or connector availability is constrained. This combination gives engineers flexibility in how the converter is interfaced to the surrounding digital system. Active laser trimming of thin-film resistors improves the stability and matching of the internal resistor network. Trimming allows calibration during manufacture to reduce offsets and improve accuracy. The hybrid IC implementation combines MSI digital circuitry with linear monolithic chips, combining digital conversion control and analog measurement functions within one device. The internal reference and buffer amplifier also reduce the number of external precision components required for basic operation. The AD572 is suitable for industrial data acquisition, process-control instrumentation, test and measurement equipment, embedded control systems, and legacy computer interfaces. It is particularly appropriate when a design requires a complete 12-bit converter with both parallel and serial outputs rather than a high-speed streaming ADC. The tube packaging and 32-pin SBCDIP outline also suit instruments and industrial systems built around through-hole analog and mixed-signal assemblies. Designers should verify signal levels against the converter's input and reference ranges, establish the correct conversion timing for the selected interface, and provide suitable bypassing around the supply and analog input pins. Because this is a conventional through-hole hybrid converter, board area and interconnect length may favor a more modern surface-mount ADC, but the AD572BD can simplify qualification of older industrial platforms. This page combines the manufacturer's product information with engineering-oriented guidance on conversion interfaces, accuracy, application fit, and design considerations. It also distinguishes verified product characteristics from details that must be confirmed in the complete Analog Devices AD572 documentation before schematic release or production use.

Analog Devices AD573JD is a complete 10-bit successive-approximation analog-to-digital converter with an integrated reference, clock, and comparator, operating from +5 V and -12 V or -15 V supplies in a 20-pin hermetically sealed ceramic DIP package. It converts an analog input into a 10-bit digital result with a typical successive-approximation conversion time of 20 µs and supports full or 16-bit microprocessor-bus interfacing. An ADC is an interface IC that translates a continuously varying analog voltage into a digital code for processing, measurement, or control. The AD573 belongs to the SAR ADC family, whose internal comparator repeatedly selects residual-voltage bits until the 10-bit conversion is complete. Because the AD573 includes its reference, clock, and comparator, the manufacturer describes it as a complete converter requiring no external components to perform a conversion. The AD573's principal engineering features include a 10-bit conversion resolution, no missing codes over temperature, and operation from +5 V and either -12 V or -15 V supplies. These characteristics make it suitable for instrumentation, industrial monitoring, sensor measurement, data acquisition, and embedded control systems where a compact parallel-output ADC is appropriate. The AD573 family is available in multiple package configurations, including 20-pin hermetically sealed ceramic DIP. The manufacturer product page states that AD573J and AD573K versions can also be supplied in a 20-pin plastic DIP or 20-pin leaded chip carrier. The AD573JD ordering code identifies the hermetically sealed ceramic DIP configuration, whose package is suited to demanding temperature-range and reliability environments. Typical uses include digitizing transducer outputs in industrial measurement systems, acquiring slowly changing sensor signals in data-acquisition equipment, monitoring process variables in instrumentation, and feeding sampled analog data into microprocessor-based embedded controllers. The parallel digital interface simplifies connection to systems with dedicated data and control buses, while the integrated converter functions reduce external component count. Designers should verify the complete pinout, electrical limits, timing relationships, reference behavior, input range, and bus interface against the manufacturer datasheet before layout or replacement qualification. Because the device uses a negative supply alongside +5 V, bypassing and grounding must be planned carefully. A replacement should be accepted only when its package, pin assignment, logic levels, supply requirements, conversion timing, and temperature grade are verified as compatible. This page consolidates the verified AD573JD converter characteristics, package information, application guidance, sourcing caveats, and replacement constraints. It also distinguishes verified facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers avoid treating an incomplete distributor listing as a complete design specification.

AD573JN

AD573JN - 10-Bit SAR ADC with 20 us Conversion | Analog Devices

Analog Devices AD573JN is a complete 10-bit successive-approximation analog-to-digital converter with a 20 us typical conversion time, packaged in a 20-pin PDIP. It integrates a DAC, voltage reference, clock, comparator, successive-approximation register, and three-state output buffers on one monolithic chip, reducing the external circuitry required for a standalone data-acquisition front end. According to the Analog Devices AD573 product page, performance is guaranteed with +5 V and either -12 V or -15 V supplies, and a version compliant with MIL-STD-883 is available. An ADC converts a time-varying analog voltage into a numerical representation for processing by a microprocessor, controller, or other digital logic. The AD573 belongs to the SAR ADC hierarchy: during each conversion, its internal DAC generates successive trial voltages for the comparator, and the successive-approximation register records the binary result. This complete converter category includes the reference, clock, comparator, SAR logic, and digital output interface in one device. Key features include 10-bit resolution, one analog input, a typical successive-approximation conversion time of 20 us, no missing codes over temperature, operation from a +5 V supply with a negative -12 V or -15 V supply, and a monolithic implementation. Separate HBE and LBE inputs enable the eight most-significant bits or the two least-significant bits for straightforward connection to narrower microprocessor buses. The AD573JN uses a parallel digital interface rather than a serial protocol. The manufacturer datasheet identifies DB9 through DB2 on pins 10 through 3, with HBE on pin 20 and LBE on pin 19; DB1 and DB0 occupy pins 2 and 1. Its integrated reference, clock, comparator, and output buffering simplify system implementation, although the negative supply requirement and parallel-bus wiring remain important constraints. Typical uses include industrial process-control instrumentation, laboratory measurement equipment, legacy microprocessor data-acquisition systems, embedded control panels, and educational analog-measurement platforms. The 20 us typical conversion time favors sampled or multiplexed measurement systems rather than high-frame-rate waveform acquisition, while the 10-bit result provides approximately 1024 addressable output codes. Designers should verify input-range, reference, timing, and logic-level details against the manufacturer datasheet before layout. Decoupling, grounding, bus timing, and unused digital outputs require careful treatment because this legacy-style converter combines analog and digital functions in one package. The cited supply configurations should be followed exactly rather than assuming conventional single-supply operation. This product record consolidates manufacturer functionality, distributor package information, interface details, and verified drop-in candidates. It also separates documented specifications from unavailable parameters, making the engineering trade-offs and replacement uncertainty explicit rather than presenting unverified values as production-ready design data.

AD573JP

AD573JP - 10-Bit SAR ADC with Parallel Output | Analog Devices

The Analog Devices AD573JP is a complete 10-bit successive-approximation analog-to-digital converter with integrated reference, clock, comparator, successive-approximation register, DAC, and three-state output buffers, packaged in a 20-pin PLCC. It converts one single-ended analog input into a 10-bit parallel digital result. The verified product information identifies the AD573 as a 10-bit SAR ADC with a typical conversion time of 20 µs, no missing codes over temperature, and operation using +5 V and -12 V or -15 V supplies. The AD573JP is specified for 20-PLCC, 9 x 9 mm packaging and is offered by distributors as a single-input, single-channel ADC. An ADC is an analog-to-digital converter, a category of data-conversion ICs that translates a continuously varying voltage into a numeric value. The AD573's successive-approximation architecture is a complete mixed-signal subsystem rather than only a comparator or front end. Within the hierarchy of semiconductor components, the AD573JP is an ADC, then a data-converter IC, then an integrated circuit. Its internal reference and parallel bus make it useful when an embedded controller needs direct digital access without an external reference or serial conversion interface. Key features include complete 10-bit conversion, integrated voltage reference and clock circuitry, parallel microprocessor-bus-compatible output, and three-state output buffers. The converter uses a successive-approximation conversion process rather than a flash or pipeline architecture. Its parallel interface can connect directly to suitable digital bus logic or microprocessor input circuitry, reducing the need for a serial protocol. The specified power-supply arrangement supports +5 V and either -12 V or -15 V analog supplies, so the device is intended for systems able to provide the required positive and negative rails. The AD573 architecture is relevant where a moderate-resolution measurement must be acquired deterministically and presented in parallel. Because the converter includes a DAC, voltage reference, clock, comparator, SAR register, and output buffers on one chip, the system designer can focus on input conditioning, bus interfacing, timing, and reference-quality requirements. Its 10-bit resolution represents 1024 quantization levels, while the 20 µs typical conversion time provides a defined sampling interval for industrial control, instrumentation, and legacy microprocessor systems. Typical applications include industrial process measurement, laboratory instrumentation, digital panel meters, transducer signal acquisition, and embedded control systems with parallel buses. The input front end still requires careful attention to source impedance, acquisition time, input range, grounding, and noise. The positive and negative supply requirements must be checked against the system power architecture before layout begins, especially when replacing the converter with a different ADC family. A key design consideration is bus contention. The three-state outputs allow multiple devices or bus transceivers to share parallel data lines, but the system must ensure that only one output driver is enabled at a time. Input settling, conversion control, and the relationship between the internal clock and external bus timing should be verified against the manufacturer datasheet. This product page consolidates verified manufacturer and distributor information, package details, sourcing links, functional guidance, and explicitly separated uncertainties. It distinguishes documented AD573JP characteristics from parameters that require confirmation from the complete manufacturer datasheet before layout or production release.

Its digital outputs are suitable for parallel-processing systems, instrumentation, and industrial control equipment. The AD573 family is a complete converter according to the manufacturer product page, and no external components are required to perform a conversion. This simplifies analog front-end design when the available input range and acquisition rate meet the application requirements. The single-ended input arrangement also keeps the signal interface straightforward, although system-level grounding and signal conditioning remain essential for reliable measurements. Typical uses include process monitoring, industrial data acquisition, instrumentation, laboratory equipment, and embedded control systems. Designs must accommodate the converter's separate positive and negative supply requirements and interface its parallel outputs correctly to the host controller, counter, latch, or digital bus. When laying out the AD573KD/+, place the device close to the analog source and provide suitable bypass decoupling on the supply pins. The ceramic DIP package is suited to conventional through-hole assembly rather than high-density surface-mount designs. Confirm the complete pinout and timing behavior against the manufacturer datasheet before finalizing routing. This page consolidates verified manufacturer and distributor information for the AD573KD/+, adds application-focused design context, distinguishes confirmed specifications from unavailable details, and clearly records that no verified pin-to-pin substitute was found rather than presenting a merely similar converter as a drop-in replacement.
