DAC80H-CBI-I - 12-Bit Digital-to-Analog Converter | Burr Brown
DAC80H-CBI-I

DAC80H-CBI-I - 12-Bit Digital-to-Analog Converter | Burr Brown

The Burr Brown DAC80H-CBI-I is a 12-bit digital-to-analog converter (DAC) designed for converting digital code streams into corresponding analog voltage or current signals. The verified distributor record identifies it as a digital-to-analog converter, while detailed electrical characteristics, supply requirements, interface format, output architecture, and package dimensions require confirmation from the manufacturer datasheet. The available source data does not provide enough verified information to safely populate those parameters. Its DAC80H naming places it in the family of precision and high-speed converter applications, but the exact device family architecture should be treated as unverified until the original datasheet is obtained. Engineers should use the DAC80H-CBI-I as a converter-level component rather than assume compatibility with a modern audio DAC without checking pinout, logic levels, settling time, and output circuitry. A digital-to-analog converter is a data-conversion integrated circuit that maps a digital input code to an analog output. DACs belong to the broader semiconductor hierarchy of interface ICs, converters, and signal-chain components. They are used wherever a digital system must produce a continuously variable analog quantity, including audio reconstruction, waveform generation, instrumentation, communications, industrial control, and test equipment. The usefulness of a DAC depends on resolution, accuracy, conversion speed, output noise, reference accuracy, supply requirements, digital interface compatibility, and output buffering. The verified record specifically identifies a resolution of 12 bits. This means the converter represents each digital sample with a 12-bit code, corresponding to 4,096 possible code values when the full range is used. However, total error, integral nonlinearity, differential nonlinearity, monotonicity, and effective noise are not present in the supplied records and must not be inferred from resolution alone. The converter may be used for instrumentation or signal generation, but its suitability for audio, RF, or high-speed communications depends on the missing timing and noise specifications. A DAC80-family design should be reviewed at the circuit level. Digital input timing, write or latching signals, reference voltage, analog supply sequencing, output loading, and layout all affect usable performance. The output stage may require op-amp post-amplification, current-to-voltage conversion, or filtering, but those details are not specified in the verified data. Do not select external components or PCB routing until the exact pinout and electrical limits are confirmed from the manufacturer documentation. Typical potential uses for a 12-bit DAC include laboratory signal generation, programmable voltage references, digital control systems, embedded instrumentation, audio signal reconstruction, and industrial test equipment. The actual application should be selected only after confirming output range, settling behavior, digital interface, and reference requirements. For new designs, verify the package drawing, pin numbering, supply voltages, absolute maximum ratings, and timing specifications directly with the manufacturer or authorized distributor. A key design consideration is to treat the datasheet as the authority for electrical limits and layout. The supplied search results confirm identity, function, and 12-bit resolution, but not the complete pinout or application circuit. Verify grounding, reference routing, decoupling, analog and digital supply separation, and output filtering before layout release. This page synthesizes verified distributor identity information, availability references, and engineering guidance while clearly identifying missing technical data rather than inventing specifications.

DAC81416RHA - 16-Ch 16-Bit High-Voltage Output DAC | Texas Instruments
DAC81416RHA

DAC81416RHA - 16-Ch 16-Bit High-Voltage Output DAC | Texas Instruments

The Texas Instruments DAC81416RHA is a 16-channel, 16-bit, buffered, high-voltage output digital-to-analog converter (DAC) integrated into a 40-pin VQFN (6x6 mm) package. It belongs to the DACx1416 family (which also includes the 12-bit DAC61416 and 14-bit DAC71416), and it provides up to 16 high-voltage analog outputs with 12 µs typical settling time, integrated low-drift 2.5 V internal reference, and a maximum analog output swing of ±20 V. The device communicates via a 4-wire serial peripheral interface (SPI) compatible with logic levels up to 5.5 V, enabling direct connection to most host microcontrollers, FPGAs, or DSPs. A high-voltage output DAC is a precision data converter that synthesizes analog voltage signals (rather than low-level current-mode outputs) directly from a digital codeword. Compared to current-output DACs (such as multiplying-R2R or R-2R ladder types), high-voltage-output DACs integrate the output amplifier on-chip, eliminating the need for an external op-amp and signal-conditioning stage in applications such as industrial process control, optical networking bias control, and automated test equipment. Within the broader power management and signal chain hierarchy, a high-voltage DAC sits between a digital controller and an analog actuator: microcontroller -> DAC -> driver amplifier -> load. Key features of the DAC81416RHA include 16-bit monotonic operation, high linearity of ±4 LSB (max) INL, integrated 2.5 V reference with 5 ppm/°C typical drift, per-channel programmable gain and offset calibration registers, hardware LDAC pin for simultaneous output updates, and a wide AVDD supply range up to 41 V. The integrated reference eliminates the need for an external precision reference in most applications, simplifying BOM count and saving board space. The DAC81416RHA uses a precision R-2R ladder architecture combined with an output buffer capable of sourcing and sinking 5 mA per channel. Per-channel calibration registers correct for system-level zero and full-scale errors, while the wide analog output voltage range allows direct drive of high-voltage actuators, PIN diode attenuators, and proportional control loops. The device is also pin-compatible with the 14-bit DAC71416RHA and 12-bit DAC61416RHA, providing design scalability. Typical applications include optical networking (laser bias control, VOA attenuators), industrial process control (valve and pump control), automated test equipment (ATE) pin electronics, programmable power supplies, and bias-current generation for MEMS devices. The 16 independent channels also suit multi-axis motion-control boards that require synchronized analog setpoints. When designing with this DAC, ensure that the AVDD supply provides adequate headroom for the desired output swing and that adequate bulk decoupling is placed near the AVDD and AVSS pins. The LDAC pin enables simultaneous output updates across all channels, which is critical for scope- and waveform-synchronized actuation. This page synthesizes distributor pricing for the DAC81416RHA from authorized sources, drop-in pin-compatible alternatives from the same DACx1416 family, and practical PCB layout notes not found in the manufacturer datasheet alone.

DAC8229FS-REEL

DAC8229FS-REEL - Dual 8-Bit Voltage-Output DAC | ADI

The Analog Devices DAC8229FS-REEL is a dual 8-bit, voltage-output, multiplying CMOS digital-to-analog converter with two independent DAC channels and a 20-lead SOIC package. Each channel provides 8-bit resolution, accepts a reference input of ±2.5 V, and uses an internal amplifier to generate an inverted voltage output. According to the manufacturer datasheet, the device can also accept a -10 V reference and produce a corresponding +10 V output. A DAC is a digital-to-analog converter, a semiconductor category used to translate digital codes into proportional voltage or current signals. The DAC8229 belongs to the voltage-output DAC family within the broader data-converter IC and signal-processing semiconductor hierarchy. Its multiplying architecture means that the output voltage scales with the applied reference signal, making the converter useful when designers need adjustable analog output under software or control-system direction. The primary features of the DAC8229 include dual-channel operation, 8-bit resolution, and voltage outputs with inverted polarity. The reference input range is ±2.5 V, while a -10 V reference is supported for operation extending to a +10 V output. The manufacturer datasheet also states that the converter dissipates less than 109 mW in the 20-pin 0.3-inch DIP or 20-lead SO surface-mount package, helping control heat in compact multi-channel equipment. Internally, the DAC8229 uses multiplying CMOS DAC elements and output amplifiers. Each digital input code controls the ratio between the external reference and the analog output, with the internal amplifier providing the required inversion. This structure allows one reference source to establish the scaling for both converter channels, although independent reference routing may be used when the two outputs require different scaling or isolation. Typical uses include programmable analog control, industrial test equipment, instrumentation, communications equipment, and digital-to-analog interface subsystems. It is particularly appropriate where two low-resolution analog outputs are required without allocating separate converter packages. Its multiplying reference architecture can support gain adjustment, waveform generation, and closed-loop actuator or test-signal control when paired with suitable external circuitry. The principal design consideration is reference polarity and range. A +2.5 V reference produces an inverted output with respect to the digital code, while a -10 V reference permits a corresponding +10 V output. Input and reference bypassing should be placed close to the device, and output loads must remain within the limits stated by the manufacturer datasheet. Designers should also account for supply sequencing and analog settling time. This page consolidates the verified manufacturer specifications, packaging information, sourcing links, comparison fields, and application guidance into a design-focused reference for the DAC8229FS-REEL. It also distinguishes verified values from specifications that still require confirmation from the datasheet or an authorized distributor.

DAC8408BIHP - Quad 8-Bit DAC with Memory | Analog Devices
DAC8408BIHP

DAC8408BIHP - Quad 8-Bit DAC with Memory | Analog Devices

The Analog Devices DAC8408BIHP is a monolithic quad 8-bit multiplying digital-to-analog converter with memory, integrating four DAC channels in a 28-pin plastic package. Each channel provides its own reference input, feedback resistor, and onboard data latch with read/write capability. The device supports TTL/CMOS-compatible microprocessor interfacing and four-quadrant multiplication. A verified manufacturer listing confirms the quad 8-bit CMOS architecture; detailed electrical limits not present in the supplied web data remain identified as data needed. A multiplying DAC is a digital-to-analog converter whose output is proportional to both an input reference and an 8-bit digital code. In a multiply application, changing the reference voltage scales the converter output without changing the stored digital word. This makes the DAC useful where a control signal must attenuate, modulate, or calibrate an analog level. Four converters on one chip also reduce board area and simplify multi-channel system control. The DAC8408 family provides guaranteed monotonic DACs, endpoint linearity to 1/4 LSB, and DAC matching within 1%, as reported in the supplied indexed datasheet excerpt. Each channel has independent reference input and feedback circuitry, while the integrated latches support digital readback. These features make the device suitable for instrumentation, waveform generation, programmable gain or attenuation, automated test equipment, and four-channel control systems. The BIHP ordering code is associated with Analog Devices and the indexed product results describe the DAC8408 as a quad 8-bit multiplying CMOS D/A converter with memory. The supplied results do not provide a confirmed package designation, pin map, supply range, temperature range, settling time, reference voltage, output compliance, or lifecycle classification. Those values must be confirmed in the manufacturer datasheet before layout or production release. Designers should treat each DAC reference and feedback path as an analog signal path. Keep digital control traces away from reference and feedback nodes, provide a stable reference source, and follow the manufacturer’s recommended bypass and grounding arrangement. Because this is a CMOS converter, unused channels and unused digital inputs should be connected according to the datasheet rather than left floating. Verify output compliance and load-current limits before driving downstream circuitry. This page synthesizes the verified product description, source links, and engineering gaps from the supplied web results. It does not invent missing electrical values, package dimensions, pin assignments, or replacement claims. Use the Analog Devices product page and manufacturer datasheet as the controlling references for production design. For purchasing, price, stock, and lead time should be checked against current authorized distribution. The provided web results include a Rochester listing and an Octopart reference, but they do not establish XAIPART inventory or a guaranteed delivery commitment.

DAC8408FS-REEL

DAC8408FS-REEL - Quad 8-Bit DAC with Memory | Analog Devices

The Analog Devices DAC8408FS-REEL is a monolithic quad 8-bit multiplying CMOS digital-to-analog converter with memory, packaged in a 28-pin SOIC. Each of the four converter channels has an independent reference input, feedback resistor, and onboard data latch with read/write capability. The device guarantees endpoint linearity to 1/4 LSB, maintains monotonic operation, and provides DAC matching within 1%. A digital-to-analog converter is an interface integrated circuit that translates digital code words into proportional analog voltages or currents. A multiplying DAC differs from a fixed-output converter because its output depends on both the digital input code and an external reference. Within the electronics hierarchy, the DAC8408 belongs to the ADC/DAC class of data-conversion ICs used to connect digital processing systems with analog instrumentation, control, or signal-generation circuits. The four-channel architecture reduces component count when a system requires several independently controlled analog outputs. Read/write-compatible latches allow the converter to retain digital information and support microprocessor or computer interfacing. The manufacturer description also identifies TTL/CMOS compatibility, four-quadrant multiplying operation, and processor-compatible control as important characteristics for deterministic digital-to-analog system integration. Each converter includes its own reference input and feedback resistor, allowing the four channels to use common or individual reference arrangements depending on the application. Independent references can support parallel channels with different scaling requirements, while a shared reference simplifies synchronization and tracking between channels. The guaranteed endpoint linearity and monotonicity support predictable transfer behavior in control, instrumentation, and waveform-generation systems. Typical uses include industrial process-control outputs, programmable test and measurement systems, multichannel instrumentation, industrial automation equipment, and embedded data-acquisition systems. The same-package DAC8408FSZ-REEL can serve as a directly comparable alternative when its grade and sourcing conditions are appropriate, but designers should verify the complete electrical specification and ordering information before substitution. The primary design consideration is reference and feedback implementation. Because the DAC is multiplying, reference quality and stability directly influence output accuracy. Layout should keep reference and analog-output paths compact, provide a low-impedance return for each channel, and isolate digital write activity from sensitive analog nodes. The 28-pin SOIC footprint also requires attention to thermal performance when all four channels operate continuously. This page consolidates the verified manufacturer description, distributor sourcing information, practical application guidance, and a conservative same-package comparison. Because the supplied search snapshot does not expose numerical pricing, pin assignments, or a qualified drop-in cross-reference set, unavailable engineering fields are explicitly identified rather than inferred.

DAC8512FS-REEL

DAC8512FS-REEL - 12-Bit Serial DAC | Analog Devices

The Analog Devices DAC8512FS-REEL is a complete 12-bit voltage-output digital-to-analog converter designed for single +5 V operation. It integrates a DAC, input shift register, latches, voltage reference, and rail-to-rail output amplifier in an 8-pin SOIC package. The serial interface uses three wires for data input, clock, and load strobe, with an additional chip-select function supported by the DAC8512 family. A digital-to-analog converter, or DAC, converts digital code words into proportional analog voltages or currents. The DAC8512 belongs to the voltage-output DAC hierarchy, combining a digital interface and conversion core with an analog output stage. This integration gives embedded and control designers a compact way to add programmable analog output to instruments, industrial equipment, and other +5 V systems without implementing a separate converter, reference, and output amplifier. The key verified features of the DAC8512 include 12-bit resolution, a +5 V supply requirement, natural binary coding, a serial input interface, an integrated reference, and a rail-to-rail output amplifier. Its three-wire serial interface is compatible with DSP-style data transfer using SDI, CLK, and load strobe signals. The chip-select capability also supports arrangements containing multiple converters, provided the system drives the interface signals correctly. Internally, the device combines a binary-weighted R-2R DAC core with a serial shift register and latching circuitry. The shift register accepts the digital word, while the latch preserves the selected code for conversion. The integrated reference establishes the conversion scale, and the rail-to-rail output amplifier supports the output range specified for the device. The manufacturer describes the DAC8512 as being built with CBCMOS process technology. Typical uses include programmable test and measurement equipment, industrial process-control outputs, instrumentation, laboratory interfaces, and embedded systems that require a compact 12-bit analog output. In each case, the serial interface reduces the number of required data lines, while the integrated reference and output amplifier simplify the analog output implementation. Designers should account for the +5 V supply requirement, reference-decoupling recommendations, logic-level compatibility with the host controller, and the available output range defined by the Analog Devices datasheet. The DAC8512FS-REEL is supplied on tape and reel for automated production assembly, while its 8-pin SOIC package supports conventional surface-mount PCB construction. This product record combines verified manufacturer information with distributor availability references, package details, technical specifications, selection guidance, and practical design notes. It also documents why the available same-family alternatives must be checked carefully rather than treating every similarly described DAC as a true pin-to-pin replacement.

DAC8740HRGER - Low-Power Fieldbus Modem | Texas Instruments
DAC8740HRGER

DAC8740HRGER - Low-Power Fieldbus Modem | Texas Instruments

The Texas Instruments DAC8740HRGER is a low-power HART, FOUNDATION Fieldbus, and PROFIBUS PA-compatible modem with a UART interface, offered in a 24-VQFN 4 x 4 mm package. The verified distributor listing identifies the interface and package, while the manufacturer describes the DAC874xH family as a half-duplex physical-layer modem for industrial process-control and automation systems. Its supported industrial protocols make it suitable for connecting sensors, actuators, transmitters, controllers, and field equipment. A fieldbus modem is an interface IC that converts digital UART information into the physical signaling required by an industrial fieldbus, and it can also receive and decode the corresponding bus waveform. In the HART mode described by Texas Instruments, the DAC8740H integrates the circuitry required for half-duplex HART physical-layer operation in slave or master configurations, reducing the amount of external circuitry needed by the transmitter. FOUNDATION Fieldbus and PROFIBUS PA compatibility broadens its relevance in process plants and industrial automation networks. The verified product data establishes the 24-VQFN 4 x 4 mm package and the UART-based architecture, but it does not provide a complete electrical parameter table in the supplied excerpts. Consequently, operating voltage, current consumption, baud rate, analog performance, temperature range, and protection limits are retained as datasheet-needed fields rather than inferred from the product family name. This conservative approach prevents protocol, supply, and signal-integrity assumptions from entering a design prematurely. The DAC8740HRGER is positioned for industrial measurement and control rather than ordinary consumer UART links. Its fieldbus compatibility is relevant when a controller must communicate with a 2-wire industrial process network through a defined physical layer. The UART interface gives the host processor a familiar digital connection, while the integrated modem circuitry reduces the design burden associated with waveform generation, reception, filtering, and bus coupling. Exact baud-rate and loading requirements should be checked against the complete manufacturer documentation before schematic release. Typical application areas include HART-connected pressure and temperature transmitters, FOUNDATION Fieldbus process instruments, PROFIBUS PA field devices, industrial controllers, sensor gateways, actuator interfaces, and factory automation equipment. The compact VQFN package helps reduce board area compared with larger leaded implementations, although exposed-pad layout, thermal performance, grounding, and high-speed signal routing must be handled according to the manufacturer's land pattern and layout guidance. The most important design step is to select the external network components and protection scheme around the exact bus topology, cable length, and operating mode. Fieldbus transceivers are exposed to industrial transients and long cables, so power-supply filtering, surge protection, grounding, connector design, and separation from noisy switching nodes deserve careful review. Verify pin-level multiplexing, supply sequencing, decoupling, and exposed-pad connections against the complete datasheet before layout sign-off. This page combines the verified manufacturer identity, protocol positioning, package information, distributor references, and engineering cautions. It is intended to help engineers locate the correct device, understand its industrial interface role, and identify which datasheet parameters still require confirmation before a production design is released.

DAC8740HRGET - 2.7V-5.5V HART/Fieldbus Modem | TI
DAC8740HRGET

DAC8740HRGET - 2.7V-5.5V HART/Fieldbus Modem | TI

The Texas Instruments DAC8740HRGET is a low-power HART and FOUNDATION Fieldbus modem integrated circuit with a 2.7 V to 5.5 V supply range, housed in a 24-pin VQFN 4 mm × 4 mm package. It belongs to the DAC874xH family, which supports HART, FOUNDATION Fieldbus, and PROFIBUS PA communications for industrial process-control and factory-automation equipment. The device can operate as either a half-duplex HART master or slave and is designed to minimize the number of external components required by a fieldbus physical layer. A HART modem is the physical-layer interface used to superimpose digital communication signals on 4–20 mA analog instrumentation circuits. A FOUNDATION Fieldbus or PROFIBUS PA interface similarly combines process communication with power delivery over an industrial fieldbus. These interfaces allow sensors, transmitters, controllers, and other field devices to exchange data over the same wiring infrastructure used for measurement and actuation. The DAC8740HRGET provides a compact 2.7 V to 5.5 V operating supply range for integration into modern industrial electronics. Its half-duplex operating arrangement supports both master and slave configurations, while its integrated modem functionality is intended to reduce board area and external circuitry. The VQFN-24 4 mm × 4 mm package also supports compact transmitter and receiver designs where PCB space is constrained. The DAC8740H family was created for industrial process-control and industrial-automation applications requiring interoperable fieldbus connectivity. In HART mode, the integrated circuitry is intended to perform the required half-duplex physical-layer functions with minimal external components. This makes the device applicable to transmitter boards, sensor interfaces, communication controllers, data-acquisition equipment, and connected process-control modules. Typical uses include 4–20 mA HART transmitters, FOUNDATION Fieldbus host and field equipment, PROFIBUS PA measurement devices, industrial sensor gateways, process-monitoring instruments, and factory automation controllers. Designers should verify the exact electrical limits, communication timing, external component requirements, and thermal limits against the manufacturer datasheet before finalizing a production design. A critical design consideration is selecting the correct fieldbus termination, coupling, protection, and decoupling network. The 2.7 V to 5.5 V supply range must remain valid under transient conditions, and exposed industrial connections may require surge and ESD protection beyond the modem's core communications function. Layout should keep sensitive analog and modem nodes away from high-current switching paths. This product page combines verified distributor pricing, package information, family capabilities, source links, and drop-in replacement analysis with practical industrial-interface design guidance. It distinguishes verified alternatives from broader functional equivalents so engineers can assess PCB replacement risk before committing to a redesign.

It is designed for industrial process-control and industrial-automation equipment requiring a dedicated digital communication interface for fieldbus networks. A HART modem is a physical-layer interface that adds digital communication over an analog instrumentation signal path. As a modem IC, the DAC8741H belongs to the interface-IC hierarchy, connecting embedded controllers with HART-compatible transmitters, sensors, actuators, and fieldbus equipment. The TI product page describes the device as a HART, FOUNDATION Fieldbus, and PROFIBUS PA-compliant modem suitable for both slave and master configurations in HART mode. The principal feature of the DAC8741HRGET is its SPI host interface. The verified product information states that the interface includes a DO pin for daisy-chain support, together with interrupts and other control features. This allows a host microcontroller or processor to configure the modem and exchange status and command information through a serial interface while the integrated physical-layer circuitry handles the fieldbus signal. The device is offered in a compact 24-VQFN package measuring 4 mm by 4 mm. Its industrial operating-temperature designation covers -55°C to +125°C, making the qualified ordering variant suitable for harsh industrial environments when the complete system requirements, qualification records, and application conditions are independently reviewed. The ordering suffix identifies the RGE package, and HRGET is supplied in tape-and-reel form. Typical uses include process transmitters, fieldbus sensor transmitters, industrial controllers, data acquisition equipment, remote I/O systems, and PROFIBUS PA-compatible field devices. In these systems, the DAC8741HRGET can reduce the need for discrete modem circuitry while providing a standardized host-side connection through SPI. Designers should confirm the exact receiver and transmitter implementation, timing limits, electrical levels, and external-component requirements against the manufacturer datasheet before release. The SPI signals, analog fieldbus connection, supply rails, grounding, and exposed-pad layout must be routed according to the recommended application circuit. Component availability and lifecycle commitments should also be checked for the intended production program.

DAC8742HPBS - HART Modem Interface | Texas Instruments

The Texas Instruments DAC8742HPBS is a HART modem interface integrated circuit with UART and SPI support, designed for HART, FOUNDATION Fieldbus, and PROFIBUS PA industrial communication systems. It is packaged in a 32-TQFP (5x5) package and serves as the signal-conditioning interface between a host controller and fieldbus wiring. The verified source data identifies the device specifically as a HART modem interface, while detailed electrical limits, temperature ratings, and internal interface timing remain unavailable in the supplied records. A HART modem interface is a signal-conditioning IC within the broader industrial communication and data-conversion hierarchy. It encodes and decodes Frequency Shift Keying signals used by HART-compatible fieldbus equipment. This allows an embedded controller to communicate over legacy 4-20 mA instrumentation loops without implementing the analog modulation and filtering as discrete circuitry. In a FOUNDATION Fieldbus or PROFIBUS PA installation, the modem interface supports the physical signaling layer while higher-level protocols and safety mechanisms remain the responsibility of the host system. The DAC8742HPBS is valued for integrating dedicated modem functionality into a compact 32-TQFP device. Its UART and SPI host interfaces provide selectable connectivity to embedded processors, allowing command and data transfer between the modem and application firmware. The 5x5 mm package also supports space-constrained industrial instrumentation, although exposed-pad layout and thermal verification must follow the manufacturer package drawing. Because the supplied data does not expose individual pin assignments, supply limits, isolation ratings, or accuracy figures, those details must be checked in the official DAC8742H documentation before schematic approval. Typical uses include HART-compatible sensor transmitters, pressure and flow instrument interfaces, industrial process-control modules, and FOUNDATION Fieldbus or PROFIBUS PA equipment. In these systems, the DAC8742HPBS reduces the discrete component count associated with analog modem circuitry and gives the host MCU a structured digital control path. The principal engineering trade-off is that the modem interface is only one part of the communication chain: the transmitter still requires suitable loop power, filtering, surge protection, grounding, and validated fieldbus wiring. For new designs, verify the exact device variant, supply rails, UART and SPI logic levels, receive bandwidth, transmit modulation limits, loop-current interface, and exposed-pad requirements in the official Texas Instruments datasheet. Do not derive those values from the distributor snippets. The manufacturer product page describes the DAC8742H as HART, FOUNDATION Fieldbus, and PROFIBUS PA compliant with UART/SPI support, making it the authoritative starting point for design review. This page combines verified distributor availability, manufacturer positioning, package information, replacement analysis, and practical integration guidance. It also separates confirmed facts from parameters that require datasheet verification, helping engineers avoid treating incomplete distributor metadata as a complete electrical specification.

The Texas Instruments DAC8775IRWFT is a quad-channel, 16-bit precision digital-to-analog converter with adaptive power management, programmable current output and voltage output modes per channel, housed in a 72-pin VQFN (RWF) package. It supports output ranges of 0-5V, 0-10V, ±5V, ±10V, 0-20mA, 4-20mA, and 0-24mA on each channel, and operates over -40°C to +125°C. A digital-to-analog converter (DAC) is an integrated circuit that converts a digital codeword into a corresponding analog voltage or current. The DAC8775 belongs to the precision DAC family, which in turn sits within the broader data converter category (DAC/ADC) and finally within mixed-signal semiconductors. Industrial process-control DACs like this one typically integrate the reference, output amplifiers, fault detection, and serial interface, which simplifies PLC analog-output modules and field-instrument transmitters compared to discrete solutions. Key features include integrated adaptive power management that reduces on-chip dissipation by up to 60% in voltage-output mode, 0.1% FSR total unadjusted error (TUE) for voltage outputs, ±0.05% FSR current-output TUE, 16-bit monotonic performance, integrated 5ppm/°C reference, and per-channel thermal and wire-break detection. Each channel also includes user-accessible offset and gain calibration registers. The architecture combines a quad-string DAC core with per-channel output op-amps for voltage mode and high-compliance current drivers for current mode, all clocked by a shared SPI-compatible serial interface. Adaptive power management reduces the per-channel supply voltage to the minimum required by the programmed output range, lowering on-chip power dissipation when output ranges narrower than the maximum supply are used. Typical applications include industrial process-control analog output modules, programmable logic controllers (PLCs), distributed control systems (DCS), field transmitters (4-20mA), and servo-valve drivers. The wide output range, integrated adaptive power management, and per-channel fault diagnostics make it a single-chip replacement for multi-component analog output designs. When designing, pay attention to PCB layout of the 72-pin VQFN thermal pad: a continuous ground plane beneath the exposed pad is mandatory to meet the datasheet thermal resistance. Place bypass capacitors as close as possible to the analog and digital supply pins. This page synthesizes distributor pricing, drop-in package alternatives, application notes, and design guidance not found in the manufacturer datasheet alone, giving engineers a single reference for sourcing and designing with the DAC8775IRWFT.

The Analog Devices DAC88BIEX is a 15 V companding digital-to-analog converter in an 18-pin CDIP package. It is designed for special-purpose data-acquisition applications requiring a U-255-law companding DAC, with the verified listing identifying the device as an ADCs/DACs special-purpose converter. Its architecture translates a compressed digital input representation into an analog output through a dedicated companding DAC rather than a conventional linear DAC transfer function. A companding DAC is a digital-to-analog converter that applies a nonlinear input code relationship to produce an analog level with a selected transmission-law characteristic. This class of converter belongs to the broader data-converter hierarchy: digital-to-analog converter, data converter, mixed-signal IC, and semiconductor. The U-255 law is the defining functional feature identified for DAC88BIEX in the verified manufacturer-related datasheet result. The verified data confirms a 15 V device designation and CDIP-18 package, while detailed electrical limits such as resolution, settling time, output current, reference voltage, noise, linearity, and power consumption were not included in the supplied search result. Those parameters must be confirmed in the complete DAC88BIEX datasheet before layout or production release. The listing describes the component as active data-acquisition hardware, and distributor results report availability and pricing, including a listed price of $13.62000 from icDirectory and a starting price of $14.3902 from LCSC. Typical engineering uses include compact industrial data-acquisition systems, telemetry interfaces, and legacy U-255-law signal chains where the receiving equipment expects a companding DAC. The device should be treated as a specialized converter rather than substituted for a general-purpose audio DAC. External clocking, reference, output conditioning, grounding, and decoupling must follow the datasheet recommended circuit. For new designs, verify availability, temperature grade, device revision, and electrical performance against the current manufacturer documentation. The supplied distributor evidence is sufficient for identity, category, package, function, and commercial leads, but not for unreported pin names or full timing specifications. The complete pin map is therefore left as [DATA_NEEDED] in the dedicated pinout field until the official pin table is consulted. This page consolidates verified distributor identity, pricing observations, package information, sourcing status, and application guidance while clearly separating confirmed facts from parameters that still require datasheet confirmation.

DDC112UK/1KG4

DDC112UK/1KG4 - 20-Bit Dual Current-Input ADC, 28-SOIC | TI

The Texas Instruments DDC112UK/1KG4 is a dual-input, 20-bit, charge-digitizing analog-to-digital converter (ADC) supplied in a 28-pin SOIC package (wide-body, 7.50 mm), integrating two independent continuous current-to-digital conversion channels on a single die. Each input uses a dual-switched-integrator front end that digitizes one channel while the other integrates the input charge, providing continuous integration with effectively zero dead time. According to the manufacturer datasheet, the part delivers 20-bit resolution and supports serial data output for downstream processors or FPGAs. An integrating ADC is a type of analog-to-digital converter that converts input charge (the time-integral of a current) into a digital code by transferring that charge onto an internal capacitor and measuring the resulting voltage with high precision. The integrating topology inherently rejects high-frequency noise, provides excellent linearity, and is naturally suited to low-level current signals from transducers. The DDC112 sits in the hierarchy: ADC -> integrating ADC -> charge-digitizing ADC -> data acquisition IC -> signal chain semiconductor. This makes it the right building block where precision, low noise, and direct transducer interfacing matter more than raw sampling speed. Key specifications reported by the manufacturer include 20-bit resolution, an integral linearity of ±0.005% of reading plus ±0.5 ppm FSR, and digital filter noise reduction of 3.2 ppm rms. Two differential current inputs accept low-level current-output sensors such as photodiodes directly, eliminating external transimpedance amplifiers. The device operates from a single analog supply and a digital supply, with a wide dynamic range suited to scientific and instrumentation front ends. Architecturally, the DDC112 uses continuous integration with two integrators per channel and an internal modulator that feeds a digital filter, balancing wide dynamic range against low input-referred noise. Compared with successive-approximation ADCs, the DDC112 trades conversion speed for noise rejection and DC accuracy, which is exactly the trade-off required for photosensor, dosimetry, and radiometric instrumentation applications. Typical applications include photodiode array readout for CT scanners and X-ray dosimetry, vacuum and process instrumentation charge measurement, infrared detector front ends, and high-precision weighing systems based on load cells. Anywhere a low-level current source must be digitized with sub-ppm linearity, the DDC112 class of converter is appropriate. When designing with the DDC112, allocate adequate analog and digital supply decoupling (typically 10 uF bulk plus 0.1 uF ceramic at each supply pin) and follow the recommended grounding scheme that separates analog and digital grounds at a single point near the converter. Use a low-jitter external clock if system noise from the clock would otherwise couple into the integration window.

DDC112YK/2K - Dual 20-Bit Current-Input ADC | Texas Instruments

The Texas Instruments DDC112YK/2K is a dual-input, 20-bit, charge-digitizing analog-to-digital converter (ADC) housed in a 32-pin TQFP (7x7 mm) surface-mount package. Built around continuous dual-integrator topology with simultaneous sampling and per-channel digital filtering, it delivers 3.2 ppm RMS noise and ±0.005% reading / ±0.5 ppm FSR integral linearity, programmable full-scale ranges, and a single +5V supply. What is a charge-digitizing ADC? A charge-digitizing ADC is a type of integrating analog-to-digital converter that converts input current or charge directly into a digital code, without an external front-end transimpedance amplifier. Each integrator channel continuously accumulates sensor current, while a paired second integrator on the same channel is being digitized, eliminating dead time. In the broader taxonomy, it sits within delta-sigma / integrating ADCs > data converters > signal chain ICs > mixed-signal semiconductors, and is most often deployed in photodiode, X-ray, and ionization-chamber front ends where picoamp-level currents must be resolved over a wide dynamic range. Key features include ±0.005% reading integral linearity, 3.2 ppm RMS digital-filter noise, programmable full-scale from approximately 12.5 pC to 350 pC, true integrating architecture, single +5V analog supply, cascadable serial interface, and a continuous integration scheme that maximizes channel throughput. Each of its two inputs uses two integrators in alternation, so one is integrating while the other is digitized, eliminating sample-loss gaps. The architecture combines a precision switched-capacitor integrator per channel with an on-chip 20-bit delta-sigma ADC and digital filter. Charge accumulated on the integration capacitor is digitized sequentially, while the second integrator buffers the input, giving near-100% channel duty cycle. The SPI/serial-compatible interface allows multiple DDC112 devices to be cascaded for higher channel counts. Typical applications include X-ray and CT detector readout (computed radiography arrays, baggage scanners), scintillation and photomultiplier tube front ends, nuclear medicine imaging (PET, gamma cameras), and precision analytical instrumentation such as chromatography detectors and UV/Vis absorbance spectrometers. Each role benefits from the part's ability to integrate picoamp currents directly without a noise-adding amplifier. When designing with this device, plan PCB layout around clean analog and digital ground partitioning, place the reference bypass capacitors close to the REFIN pin, and clock the converter from a low-jitter source to preserve linearity. Choosing the proper integrator capacitor value trades full-scale range against conversion rate.

DDC112YK/2KG4 - Dual Current Input 20-Bit Sigma-Delta ADC | TI

The Texas Instruments DDC112YK/2KG4 is a dual-input, wide dynamic range, charge-digitizing analog-to-digital converter with 20-bit resolution, supplied in a 32-pin TQFP (7x7 mm) package and shipped in Tape & Reel packaging. It combines two precision current-to-digital conversion channels on a single die, providing 3.2 ppm RMS digital-filter noise reduction and ±0.005% of reading (±0.5 ppm FSR) integral linearity for high-precision measurement. An ADC (Analog-to-Digital Converter) is a semiconductor device that transforms a continuous analog signal into a discrete digital code. The DDC112 belongs to the sigma-delta (Σ-Δ) ADC family — a converter architecture that oversamples the input and uses noise-shaping plus a digital filter to achieve very high resolution at moderate bandwidths. Sigma-delta ADCs sit within the broader hierarchy: ADC -> data converter -> signal chain IC -> power management & analog IC -> semiconductor. They are favored for precision sensor readout where bandwidth is traded for resolution and noise immunity. The DDC112 uses continuous charge integration with two integrators per channel — while one integrator digitizes, the other integrates — eliminating dead time and supporting up to approximately 3 kSPS per channel serial output. Low-level current-output devices such as photodiodes, photomultiplier tubes, and ionization chambers can be directly connected to its inputs, removing the need for external transimpedance amplifiers. The monolithic integration of integrators, ADC, and digital logic reduces board area, leakage paths, and noise pickup compared with discrete charge-measurement chains. Typical applications include digital X-ray detectors, charge-coupled device (CCD) signal chains, photomultiplier tube readouts, scintillation detectors, and precision analytical instrumentation such as mass spectrometers and chromatographs. The wide dynamic range suits photon-counting and low-light imaging front-ends where the input current may span six or more decades. When designing with this device, carefully manage the integration capacitors (CINTA/CINTB) and the system timing of the CONV signal to control conversion rate and full-scale range. Use guard rings around the input traces to suppress leakage, and provide low-impedance analog and digital supply decoupling close to the AVDD/DVDD pins.

The Texas Instruments DDC232CGXGR-2 is a 32-channel, 20-bit, current-input analog-to-digital converter that integrates 16 sigma-delta modulators and 32 low-level current inputs into a single monolithic device, housed in a 64-ball NFBGA (8 mm x 8 mm) package. It features a true dual-channel integrating topology with up to 3.1 kHz per-channel conversion rate, integral linearity of ±0.025% of reading ±1.0 ppm of full-scale range, and 5.3 ppm-of-FSR input-referred noise. The device operates from a +5 V analog supply and a +2.7 V to +3.6 V digital supply. What is a current-input analog-to-digital converter? A current-input ADC (sometimes called a current-to-digital converter or IDC) is a category of data converter that directly digitizes small input currents rather than voltage, replacing the traditional transimpedance amplifier (TIA) plus voltage ADC chain. Current-input ADCs belong to the broader hierarchy of analog-to-digital converters -> data converters -> mixed-signal ICs -> signal chain. By integrating charge directly on its input, a current-input ADC removes the TIA's noise, drift, and bandwidth trade-offs and is widely used in photodiode, ionization, and picoammeter front-ends where femtoampere-to-microampere signals must be digitized with high precision. Key features include 32 independent current-input channels, full-scale range from approximately 12.5 pC to 350 pC set by external capacitor and clock, serial digital interface for cascading, on-chip integration capacitors to reduce BOM, and very low power dissipation of approximately 7 mW per channel. The wide dynamic range and integrating architecture make the part well-suited for low-frequency, high-precision measurements where 50/60 Hz line rejection is required. The DDC232CGXGR-2 uses a charge-balancing, continuous-integration sigma-delta architecture per channel pair, with digital filtering that yields 20-bit noise-free codes when conversion time is sufficiently long. The -2 suffix indicates the 0 to +70 °C commercial operating temperature range, distinguishing it from the DDC232CKZXGR industrial-grade version. Two on-chip integration capacitors (CF1, CF2) can be combined or switched, allowing four full-scale ranges to be programmed without external capacitors in most applications. Typical applications include X-ray and CT detector arrays, photodiode array readout, gas chromatography detectors, multi-channel ionization chambers, scintillation detector front-ends, and analytical instrumentation such as mass spectrometers. The integrating topology intrinsically rejects 50/60 Hz line frequency interference, which is essential for sensitive laboratory and medical measurements. When designing with this device, ensure the input bias currents do not exceed the integrator's specified range and provide adequate input protection if the source can overdrive. Decouple analog and digital supplies with 0.1 µF and 10 µF capacitors placed as close to the supply balls as possible, and keep analog and digital grounds separated until tied at a single point.

DG187AA - SPST Analog Switch, JFET, TO-100-10 | Vishay

The Vishay Siliconix DG187AA is a single-channel SPST (single-pole single-throw) analog switch built around an N-channel JFET switching element with an integrated level-shifting driver. Housed in a 10-pin TO-100 metal can package (round, through-hole, 10 leads), it provides approximately 30 Ohm on-resistance and is part of the DG181 through DG191 analog-gate family originally introduced by Intersil and now manufactured by Vishay Siliconix. According to the verified distributor listings, it is categorized as an SPST analog switch IC. An analog switch (also called a JFET analog gate or solid-state analog switch) is an electronic component that uses a semiconductor device (typically a JFET or MOSFET) to connect or disconnect an analog signal path under the control of a digital logic input. Analog switches sit within the broader taxonomy of signal switches -> multiplexers/switches -> interface ICs -> integrated circuits, and they are essential whenever an analog signal must be routed without injecting distortion, charge injection, or significant series resistance. The DG187AA's JFET architecture keeps the on-resistance relatively constant over a wide analog signal range, which is a key advantage over simple MOSFET-only designs in precision instrumentation. Key differentiating features of the DG187AA include: (1) a high-speed level-shifting driver that accepts low-level CMOS/TTL-compatible inputs (down to approximately 0.8V to 2V) and uses them to control the JFET switch state, (2) analog signal range operation that suits both unipolar and bipolar audio/precision signals, (3) low charge injection thanks to the JFET topology, and (4) a hermetic TO-100 metal can that supports military temperature grades (-55C to +125C). The metal-can packaging also provides excellent EMI shielding for sensitive analog signal routing in instrumentation front-ends. In terms of electrical architecture, the DG187AA integrates the JFET switch die and the level-shifting driver die within a single TO-100 can, allowing the part to be driven directly from logic-level inputs without external pull-ups or level translators. This single-package integration reduces board area and simplifies PCB layout compared with discrete JFET-plus-driver implementations. The switching speed, while not as fast as modern CMOS analog switches, is sufficient for audio, instrumentation multiplexing, sample-and-hold front-ends, and legacy industrial signal routing. Typical applications for the DG187AA include: (1) precision instrumentation multiplexers, (2) audio signal routing in professional and broadcast equipment, (3) sample-and-hold amplifier front-ends, (4) data-acquisition system signal gating, (5) legacy industrial process-control signal switching, and (6) military and aerospace signal routing where the TO-100 hermetic can is required. The MIL-spec /883 variant (DG187AA/883) confirms the part's qualification for harsh-environment designs. When designing with the DG187AA, note that the TO-100 package has 10 leads arranged in a circular metal can, with pin 1 typically marked by a tab or dot near the package base. Because the package is a through-hole metal can (not surface-mount), PCB layout requires plated through-holes on a 0.230 inch lead circle typical of TO-100 cans. Always consult the manufacturer datasheet for the exact pinout, especially when migrating from the /883 to the commercial-temperature variant.

It supports dual-supply operation from ±4.5 V to ±18 V and is designed for general-purpose routing of analog signals in communications, instrumentation, process-control, and computer-peripheral equipment. An analog switch is a semiconductor device that routes signals between circuit nodes under digital control. The DG211CJ+ belongs to the hierarchy of analog switches, multiplexers, interface ICs, and semiconductor components. Its four single-pole single-throw channels provide normally closed paths, making it useful when a system must maintain a connection until an active control signal changes the selected route. The device provides a maximum on-resistance of 175 ohm and a 1:1 signal configuration across four circuits. The manufacturer identifies the DG211 family as CMOS analog switches with low cost and general-purpose switching functions. Operation across positive and negative supplies supports bipolar analog signals in instrumentation and signal-routing systems, while the individual digital controls allow each channel to be operated independently. The DG211 and DG212 devices are described by the manufacturer as normally closed, quad SPST CMOS analog switches that can operate with supplies from ±4.5 V to ±18 V. Maxim also states that the DG211 family will not latch up if the power supplies are disconnected while input signals remain connected, and the devices feature guaranteed break-before-make switching. These characteristics help control transient current and undefined states during control transitions. Typical uses include analog measurement front ends, process-control interfaces, communications equipment, test equipment, and peripheral signal routing. In a measurement system, separate DG211CJ+ channels can connect sensors or reference signals to a shared analog front end while keeping unused paths connected. The device can also support signal isolation and source selection when system behavior requires a default connection that remains active until commanded otherwise. When designing a circuit around the DG211CJ+, verify input and output signal amplitudes against the supply rails, observe the control-logic thresholds, and maintain the specified continuous and peak terminal currents. Decoupling capacitors should be placed close to the supply pins, and control traces should be kept away from sensitive analog routes. The PDIP package also requires adequate insertion clearance and appropriate socket or soldering practices during assembly. This product page combines the manufacturer family information, distributor listings, cross-reference findings, package details, and practical application guidance. It highlights verified distinctions among available DG211 ordering codes and focuses drop-in comparison on the same 16-pin PDIP footprint rather than presenting surface-mount or electrically different devices as direct replacements.

DG211CY+ - Quad SPST CMOS Analog Switch | Analog Devices

The Analog Devices DG211CY+ is a monolithic quad SPST CMOS analog switch in a 16-pin SOIC package. It provides four independent single-pole single-throw channels with a maximum on-resistance of 175 ohm, operates from dual positive and negative supplies of ±4.5 V to ±18 V, and supports true bidirectional signal conduction in the ON state. A CMOS analog switch is an integrated semiconductor device that routes analog signals between circuit nodes under digital control. The DG211 family belongs to the analog-switch and multiplexer hierarchy, which supports general-purpose signal routing in communications, instrumentation, process control, and computer peripheral equipment. The DG211 switches are normally closed, so each channel connects its input to its output whenever its control input is inactive. Key features include four SPST channels, a 175 ohm maximum on-resistance, operation across ±4.5 V to ±18 V dual-supply ranges, and a 500 ns maximum off-time. According to the Analog Devices DG211 data sheet, the DG211 will not latch up when the power supplies are disconnected while input signals remain connected. Break-before-make operation is also guaranteed, which helps prevent two signal sources from being momentarily shorted together. The devices can block signals up to 30 V peak-to-peak in the OFF condition, making them useful for protecting downstream circuitry from higher-voltage external signals. True bidirectional ON-state behavior allows the same switch to route either signal direction, while the normally closed configuration provides a defined signal path during power-up and control-failure conditions. Typical applications include multimeter and test-equipment input selection, process-control signal routing, communications equipment, and peripheral interface boards. Designers should verify the control-logic thresholds, switching timing, leakage, charge injection, and absolute maximum ratings against their signal amplitude and impedance before applying the switch. This page consolidates verified manufacturer and distributor information, package and supply details, application guidance, and qualified drop-in information for DG211CY+ designs.
