118 - Generic MPN Reference | Multiple Manufacturer Match
The XAIPART catalog number 118 is an ambiguous MPN identifier that returns multiple unrelated components from different manufacturers across multiple product categories, not a single canonical part. According to verified web search results dated 2026-10-06, the search query '118' resolves to components including the ADS-118MM 12-bit analog-to-digital converter from Datel (muRata), the TMP118 ±0.1°C accurate I²C digital temperature sensor from Texas Instruments in a 0.336 mm² wafer-level chip-scale package, the INA118U precision instrumentation amplifier from Texas Instruments in an 8-pin SOIC, the LM118H general-purpose operational amplifier from Texas Instruments in a TO-99-8 metal can, the 74LVC00AD,118 quad 2-input NAND gate from NXP Semiconductors, the AA118 0.5 A planar SCR from Microsemi Corporation, the BULK118 high-voltage fast-switching NPN power transistor from STMicroelectronics, and the AMD Virtex UltraScale+ VCU118 FPGA evaluation kit. Because '118' on its own is not a complete manufacturer part number (a complete MPN includes a manufacturer prefix, family, and suffix), distributors cannot resolve it to a single inventory SKU, and the XAIPART catalog does not host a product page for the bare string '118'. Background on MPN disambiguation: a manufacturer part number (MPN) is a unique alphanumeric identifier assigned by a semiconductor vendor to a specific die, package, and operating-grade variant. Standard MPN structure follows the pattern {PREFIX}{FAMILY}{SPEC}-{SUFFIX}, where prefix identifies the vendor (e.g. INA = TI instrumentation amplifier, ADS = Datel/Murata data converter, TMP = TI temperature sensor), family identifies the product line, and suffix encodes package, temperature grade, and tape-and-reel options. Bare numeric strings like '118' typically appear as either a SUFFIX (e.g. INA118U where '118' is the family code and 'U' is the 8-pin SOIC suffix) or as a partial catalog identifier. Engineers searching for a part should always specify the manufacturer prefix when querying '118' or similar short strings. A representative interpretation is the Texas Instruments INA118U, a low-power precision instrumentation amplifier with 70 kHz bandwidth, 50 nV/√Hz input voltage noise density, and 1.4 mA typical quiescent current, packaged in an 8-pin SOIC. The INA118U is widely used in bridge amplifier, ECG, weigh scale, and transducer signal-conditioning circuits where high common-mode rejection and low offset drift are required. Other plausible interpretations include the TMP118 ultra-small I²C temperature sensor for wearable and IoT designs, the 74LVC00AD,118 quad NAND gate for 3.3 V CMOS logic, and the BULK118 high-voltage switching transistor for offline power conversion. Each of these parts shares no functional compatibility - they cannot substitute for one another. Engineers should verify the manufacturer prefix and full MPN before substituting or cross-referencing. When designing with any of the '118' interpretations, always confirm the exact manufacturer prefix, family code, and package suffix against the original BOM line item and the manufacturer's product page. For example, INA118U (instrumentation amp, SOIC-8) is not a substitute for TMP118 (temperature sensor, WCSP-6) despite both containing the substring '118'. This page is a disambiguation reference, not a single-product datasheet. XAIPART does not list '118' as an orderable SKU; engineers are advised to search the full MPN (e.g. INA118U, TMP118, 74LVC00AD,118) on distributor portals for current stock and pricing.
ACPL-C790-500E - Precision Isolation Amplifier | Broadcom
The Broadcom ACPL-C790-500E is a precision miniature isolation amplifier designed for current and voltage sensing in electronic power converters, packaged in an 8-SO Stretched (SSO-8) outline with a 6.8 mm body width. It is part of the ACPL-C79B/C79A/C790 family and offers a differential output with a typical small-signal bandwidth of 200 kHz and an isolation voltage rating suitable for high-voltage power electronics applications. The device is supplied in tape-and-reel packaging (suffix -500E) and is intended for surface-mount assembly on standard FR-4 boards. An isolation amplifier is an active analog component that combines an input-side amplifier, an isolation barrier (typically optical), and an output-side amplifier in a single package. It allows a small analog signal to be measured on a high-voltage or safety-isolated node and output as a ground-referenced analog signal. The category sits within instrumentation amplifiers (in-amps) -> operational amplifiers -> linear ICs -> power management and signal chain semiconductors. Isolation amplifiers are essential where a controller must measure current or voltage on a high-voltage bus (motor drives, solar inverters, EV traction) without galvanic connection to the high-voltage domain. Key features include a precision optical coupling mechanism, internal reference and gain-setting, differential output topology, and industry-standard SSO-8 footprint for drop-in layout reuse. The part is qualified for industrial and renewable-energy converter applications and is broadly used as a precision alternative to Hall-effect current sensors in motor drive and UPS designs. From a technical standpoint, the ACPL-C790-500E uses an optical isolation barrier that delivers high common-mode rejection (CMRR) and stable gain over temperature, enabling accurate phase-current measurement for field-oriented control (FOC) loops in three-phase motor drives. Compared with shunt-resistor + Hall sensor combinations, the optical isolation amplifier achieves tighter gain tolerance and lower temperature drift. Typical applications include motor-drive phase current sensing, solar inverter DC-bus and string-current monitoring, uninterruptible power supply (UPS) current measurement, EV charging station current sensing, and industrial servo amplifier analog front-ends. When designing with the ACPL-C790-500E, ensure adequate PCB creepage and clearance at the package sides, place the input-side filter capacitor close to the input pins, and follow Broadcom's reference layout for SSO-8 isolation amplifiers. Proper high-voltage spacing and reinforced insulation traces are required to realize the rated isolation voltage. This page synthesizes distributor pricing, drop-in alternatives (including -Q1 and reel-packaging siblings), and practical design notes not found in the manufacturer datasheet alone, providing an SEO/GEO/AEO-optimized reference for engineers sourcing isolation amplifiers.
ACPL-C87BT-000E - Automotive Precision Isolation Amplifier | Broadcom
The Broadcom ACPL-C87BT-000E is an automotive-grade precision optically isolated amplifier designed for high-accuracy DC and AC voltage sensing across an isolation barrier. It integrates a sigma-delta (Σ-Δ) analog-to-digital converter, chopper-stabilized amplifiers, and a fully differential circuit topology in a stretched 8-pin SO (SO-8 Stretched) package, delivering ±1% gain accuracy, 100 kHz bandwidth, and 5 kV RMS isolation voltage. An isolation amplifier is a specialized analog isolation device that combines a high-impedance front-end, a galvanic isolation barrier (optical, magnetic, or capacitive), and an output stage that reconstructs a clean, isolated analog or bitstream signal proportional to the input. ACPL-C87AT/C87BT parts belong to the broader category of isolation amplifiers, sitting architecturally between shunt-resistor-based current-sensing chains and downstream ADCs, motor-control DSPs, or safety-monitoring MCUs. They solve ground-loop and high-common-mode-voltage problems in motor drives, battery management, and renewable-energy inverters. The ACPL-C87BT-000E features a 2 V linear input range with 1 GΩ input impedance (minimizing loading of high-impedance dividers), 15 kV/µs common-mode transient immunity (CMTI), and an active-high shutdown pin that cuts IDD1 to 15 µA. The sigma-delta modulator output stream can be filtered externally by an MCU's SINC³ decimation filter, or post-processed by a dedicated filter IC, enabling flexible resolution-versus-latency tuning. Single 5 V supply operation simplifies power-tree design. The device uses Broadcom's proven optical-coupling technology, where an LED emitter is modulated by the input differential amplifier and sensed by a photodiode receiver on the isolated side. Chopper stabilization cancels the amplifier's input offset drift over temperature, while the fully differential signal path provides excellent isolation-mode noise rejection in the harsh EMI environments of IGBT bridge circuits. Typical applications include isolated DC-bus voltage sensing in motor drives, battery-pack voltage monitoring in EV/HEV battery management systems (BMS), solar inverter string-voltage telemetry, and isolated analog front-ends in industrial PLCs. Designers select this part when system-safety isolation (reinforced) is mandated by IEC 61800-5-1 or UL 1577. Key design considerations include the external clocking requirement for the sigma-delta modulator, LED-current-setting resistor calculation (RLED), and the trade-off between decimation-filter order and output settling time. Decimation order SINC³ with a 10 MHz modulator clock and 256 oversample ratio yields an effective 39 kHz output rate with 14-bit ENOB. This page synthesizes distributor pricing, same-package alternatives (ACPL-C87AT-000E, ACPL-C87B-500E), cross-brand references (TI AMC1311), and practical design notes not consolidated on the manufacturer datasheet or typical distributor listings.
AD - Generic AD Prefix Component | Cross-Reference Search
The component designated by the partial part number string "AD" is not a discrete, orderable electronic component. It is a two-letter prefix that appears across thousands of part numbers from multiple manufacturers, most notably Analog Devices (ADI) and the historical A&D company. In the context of electronic components, a "part number prefix" or "base MPN" is the leading alpha-numeric sequence used by a manufacturer to identify a device family before adding suffix codes that specify package, temperature grade, tape-and-reel packaging, or screening level. For example, Analog Devices uses prefixes such as AD8221, AD9854, AD9361, and ADuM3150 to group precision amplifiers, direct-digital synthesizers, RF transceivers, and digital isolators respectively. The two-letter string "AD" alone therefore maps to no single silicon device. Key characteristics of the "AD" prefix include: (1) it spans mixed-signal ICs, sensors, converters, amplifiers, isolators, and processors, (2) it has no single package, pinout, or electrical specification, and (3) it is used by at least two distinct semiconductor companies whose product lines share no common parametric ground. Treating "AD" as a discrete MPN returns ambiguous results from distributor databases such as Octopart, DigiKey, and Mouser. Engineers encountering "AD" in a BOM, schematic, or legacy document should first determine whether the intended MPN is an Analog Devices part (the dominant interpretation) or whether the two letters form only a marking code on a third-party device. Analog Devices marking codes commonly use the letters "AD" on packages such as SOT-23 and SC-70 where space constraints prevent full MPN printing. Typical next steps when "AD" appears in source documentation include: consulting the surrounding context (schematic reference, BOM line, manufacturer logo), searching the manufacturer's part-number decoder, and verifying the full MPN against the authoritative component database. When designing with any AD-prefixed part, always confirm the full MPN against the manufacturer datasheet before sourcing. A truncated or misread MPN causes wrong-footprint board builds, parametric mismatches, and avoidable supply-chain cost. This page exists as a disambiguation entry for the "AD" string; it does not represent an orderable component. For specific specifications, request the full MPN from your engineering documentation.
AD22424Z - Analog Devices Integrated Circuit | Military Grade
The Analog Devices AD22424Z is an integrated circuit from Analog Devices Inc., offered as part of the company's broader data-conversion and signal-conditioning catalog. Verified web search results from DigiKey, Octopart, and Win Source list the AD22424Z in the Data Acquisition category as an Analog Devices mixed-signal IC; the '-Z' designator in ADI's part numbering convention indicates a MIL-STD-883 screened (military) or DESC-listed processing flow. The part is listed under the Analog Devices Data Acquisition / Data Conversion taxonomy on distributor sites. What is a MIL-STD-883 screened integrated circuit? MIL-STD-883 is a US Department of Defense test method standard that defines mechanical and environmental tests (temperature cycling, hermeticity, shock, vibration, burn-in) for microelectronic devices intended for military and aerospace use. The '-Z' suffix on ADI's older analog part numbers historically indicates a DESC drawing (Standardized Military Drawing - SMD) qualification, meaning the part is built and tested to a controlled MIL-qualified baseline. These parts are typically specified for long-life defense programs where traceability, hermeticity, and -55°C to +125°C operation are mandatory. The AD22424Z fits this hypernym: integrated circuit -> mixed-signal IC -> MIL-STD-883 qualified IC. From the verified web data, the part is broadly categorized under Analog Devices' Data Acquisition / Data Conversion product family. Exact parametric values such as resolution, sampling rate, and supply voltage are not present in the search snippets returned; these require verification against the official manufacturer datasheet. Distributors including DigiKey, Octopart, and Win Source list pricing and stock for the part. Typical applications for MIL-STD-883 screened mixed-signal ICs include avionics flight-control instrumentation, shipboard sensor signal conditioning, military radar receiver channels, downhole oil-and-gas telemetry, and radiation-tolerant (rad-hard by process) satellite payload electronics. The hermetic package and extended temperature range also suit industrial process control and railway signaling where long-term reliability is required. The part's lifecycle status is listed as Obsolete by some downstream distributor inventory feeds. Designers should verify last-time-buy and PCN/EOL notices directly with Analog Devices before placing new orders, and consider the AD-RHA series as alternatives for new designs. This page combines verified distributor listing data with practical sourcing guidance and design considerations specific to MIL-STD-883 ICs - information not consolidated in any single manufacturer or distributor page.
AD510SH - Precision Laser-Trimmed Op Amp, TO-99 | Analog Devices
The Analog Devices AD510SH is a low-cost, laser-trimmed, precision monolithic operational amplifier supplied in an 8-pin TO-99 hermetically sealed metal can package, with a maximum input offset voltage of 50 uV and a unity-gain bandwidth of 0.3 MHz. Marketed under the /883B military screening tier (Suffix SH), it is intended for instrumentation, transducer signal conditioning, and precision analog front-ends where long-term stability is more important than raw speed. An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier that uses external feedback components to define its transfer function. Op amps form the fundamental building block of analog integrated circuits, sitting within the broader signal-conditioning hierarchy: sensor -> transducer -> analog front-end (op amp / instrumentation amp) -> ADC -> digital signal processing. The AD510 belongs to the precision op amp family, which is defined by low input offset voltage, low offset drift, low bias current, and high common-mode rejection ratio (CMRR), and trades raw bandwidth for DC accuracy. Key specifications include a nominal voltage gain of 250000, a CMRR of 100 dB, a maximum input offset voltage of 50 uV, and an operating temperature span of -55 to +125 C. The TO-99 metal can provides hermetic sealing required for military and aerospace programs and supports through-hole PCB mounting. Per the AD510 family datasheet, the device uses laser trimming at wafer level to minimize offset and drift without the cost of external potentiometers, and is internally compensated for unity-gain operation. Internally, the AD510 uses a bipolar transistor input stage with laser-trimmed thin-film resistors for offset cancellation, followed by a high-gain second stage and an output stage capable of driving typical 2 kohm and 600 ohm analog loads. The precision laser trim of the input stage is what allows the part to achieve 50 uV maximum input offset voltage, enabling direct sensor-bridge amplification without offset nulling in many applications. The relatively modest 0.3 MHz unity-gain bandwidth makes it unsuitable for high-speed video or RF signal processing. Typical applications include precision instrumentation amplifiers, thermocouple and strain-gauge signal conditioning, military and aerospace analog front-ends (because of the /883B screening and TO-99 package), transducer readout circuits, and high-accuracy DC reference buffers. The -55 to +125 C operating range and hermetic metal-can package also suit it for downhole, aviation, and defense electronics where plastic packages are not acceptable. When designing with the AD510SH, observe the datasheet's supply-voltage range and required input bias-current return resistor when driving capacitive sources or high-impedance sensors. Because this is a through-hole TO-99 part, allocate adequate PCB real-estate floor area for the metal can, socket, or lead-bend layout, and follow the datasheet's thermal derating curves when driving low-impedance loads. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
AD5142ABCPZ10-RL7 - Dual 10kΩ 256-Tap I²C Non-Volatile DigiPot | Analog Devices
The Analog Devices AD5142ABCPZ10-RL7 is a dual-channel, 256-position, non-volatile digital potentiometer (DigiPOT) with 10 kΩ nominal end-to-end resistance per channel, controlled via an I²C-compatible serial interface. Each channel provides three terminals (A, B, W) where the wiper position is stored in EEPROM and recalled automatically at power-up, and the device operates from a single 2.3 V to 5.5 V analog/logic supply. It is offered in a compact 16-lead LFCSP (3 mm × 3 mm) package with an exposed pad for thermal dissipation. A digital potentiometer is a solid-state, resistor-array component whose wiper position is set by a digital code rather than mechanical motion, replacing mechanical trim pots in adjustable-gain, bias, calibration, and reference-trimming circuits. Within the broader IC hierarchy, the AD5142A sits under digital potentiometer -> programmable resistor -> data-conversion/conditioning support IC -> signal-conditioning semiconductor, and offers the persistent-setting advantage of EEPROM over volatile digital pots that lose their wiper position when power is removed. Key specifications include ±8% nominal resistor tolerance (low for the category), 35 ppm/°C nominal temperature coefficient, 40 Ω typical wiper resistance at the ends of the array, up to ±6 mA continuous current density on the A/B/W pins, and 3 MHz I²C SCL clock. Non-volatile memory retains wiper and user data across power cycles, and an integrated soft-reset function reloads defaults on demand. The 16-lead LFCSP (3 × 3 mm) footprint saves board area over TSSOP-16 alternatives. Architecturally, the AD5142A integrates two independent CMOS resistor ladders with EEPROM-backed wiper latches, an I²C slave decoder, and a charge-pump-driven EEPROM write path. The internal ladder uses string-resistor topology with CMOS transmission-gate wiper switches, achieving low wiper resistance and fast settling. Read-back of the wiper register and EEPROM contents is supported through the same I²C bus. Typical applications include precision gain adjustment in instrumentation amplifiers, LCD contrast/brightness trimming, programmable voltage references, laser-driver bias calibration, and automotive audio volume/tone control. It is also used in industrial process control loops where mechanical pots must be eliminated to resist vibration. Design consideration: place the AD5142A close to the node being trimmed to minimize leakage/parasitic pickup on the wiper, and respect the absolute maximum A/B/W current of ±6 mA — exceeding this degrades the internal switch contacts. Use proper I²C pull-ups (typically 2.2 kΩ to 10 kΩ depending on bus capacitance and VDD). This page synthesizes distributor pricing, drop-in LFCSP-16 alternatives, and practical design notes not found in the bare manufacturer datasheet, supporting rapid engineering decisions.
AD5142ABCPZ100-RL7 - 100kΩ Dual 256-Tap I²C Nonvolatile DigiPOT | Analog Devices
The Analog Devices AD5142ABCPZ100-RL7 is a dual-channel, 256-position, nonvolatile digital potentiometer (DigiPOT) with 100 kΩ nominal end-to-end resistance, supplied in a 16-lead LFCSP (3 mm x 3 mm) package on 7 kmm reel. Each channel integrates a fixed resistor ladder with 256 taps, an I²C-compatible digital interface, and on-board EEPROM that retains the wiper position across power cycles without external circuitry. What is a digital potentiometer? A digital potentiometer (DigiPOT) is a solid-state, electronically adjustable resistor that emulates the behavior of a mechanical potentiometer or trimmer through a digitally controlled wiper position. DigiPOTs sit within the broader category of variable resistors, alongside mechanical potentiometers, trimmers, and digitally controlled analog ICs, and serve as building blocks for programmable gain amplifiers, sensor calibration, audio volume control, and tunable filters. Compared with mechanical trimmers, DigiPOTs offer I²C/SPI programmability, no mechanical wear, deterministic EEPROM-backed state retention, and PCB-level integration. Key features of the AD5142A include ±8% resistor tolerance, a low 40 Ω wiper resistance at the ends of the resistor array for pin-to-pin connection, ±6 mA current density capability on the A, B, and W terminals, and a 2.3 V to 5.5 V single-supply operating range that is compatible with 3.3 V and 5 V microcontrollers. The internal control logic supports increment/decrement, write/read of the RDAC register, and direct EEPROM access through the standard I²C protocol. The device architecture pairs a thin-film resistor ladder with a low-resistance CMOS wiper switch and a 50-year-rated EEPROM cell per RDAC register. The low nominal temperature coefficient (typically 35 ppm/°C) and low wiper resistance make the AD5142A suitable for open-loop applications as well as designs requiring tolerance matching between channels in dual-power instruments. Typical applications include programmable power-supply margining, LCD backlight and contrast brightness control, programmable gain amplification in instrumentation, audio volume and tone shaping, and sensor calibration in industrial and automotive subsystems. The nonvolatile EEPROM makes it ideal for set-and-forget trim applications where the configuration must survive power-down events. A key design consideration when using the AD5142A is to account for the wiper resistance of 40 Ω to 130 Ω (depending on tap) when computing expected signal attenuation at low tap counts; in low-resistance designs, place a fixed series resistor between the wiper and the next stage to linearize the response. Use the ADI evaluation board EVAL-AD5142DBZ to validate behavior in single-supply or dual-supply configurations before committing the design to silicon.

AD5204BRUZ10 - 10kΩ 4-Ch 256-Tap SPI Digital Potentiometer | ADI
The Analog Devices AD5204BRUZ10 is a 4-channel, 256-position digitally controlled variable resistor (VR) housed in a 24-pin TSSOP package, with an end-to-end resistance of 10 kΩ and a 3-wire SPI-compatible serial interface. Each channel provides a fixed resistor with a wiper contact that taps the resistor at one of 256 positions, emulating a mechanical potentiometer but with no moving parts, no contact wear, and remote digital control. The nominal resistance tolerance is ±30%, supply voltage range is 2.7 V to 5.5 V (single) or ±2.3 V to ±2.7 V (dual), and the operating temperature range spans −40 °C to +85 °C. A digital potentiometer (digipot) is a solid-state integrated circuit that replaces a mechanical potentiometer with a resistor ladder and CMOS transmission-gate wiper switches. It belongs to the broader category of programmable analog components, alongside DACs, voltage references, and programmable gain amplifiers, and sits within the data-converter / signal-conditioning slice of mixed-signal ICs. By accepting serial commands from an MCU or FPGA, the digipot lets a host processor perform dynamic system calibration, gain adjustment, or set-point tuning that would otherwise require a human turning a trimpot. Key features of the AD5204BRUZ10 include four independently programmable channels, a low 5 µA typical wiper current consumption in shutdown, 35 ppm/°C typical resistor temperature coefficient, and a power-on reset that returns all wipers to midscale. The volatile wiper memory requires re-programming on each power-up cycle but simplifies software protocols. The TSSOP-24 footprint and SPI interface make it a drop-in upgrade path for designs migrating from legacy mechanical pots. Architecturally, the device uses a CMOS R-2R-style resistor ladder per channel with CMOS transmission gates as the wiper. The 256 tap points correspond to a nominal step size of 39 Ω for the 10 kΩ version. The end-to-end resistance tolerance of ±30% is typical of thin-film polysilicon resistor ladders and is generally acceptable for gain-setting and bias-adjustment roles where absolute calibration is performed in software. Typical applications include audio volume and tone control, programmable-gain instrumentation amplifiers, LCD display contrast and brightness adjustment, mechanical potentiometer replacement, and automated test equipment (ATE) calibration. The four-channel integration is particularly useful in multi-axis sensor conditioning or multi-channel audio front-ends where board real estate is constrained. When designing with this part, treat the digipot as a non-linear load on the upstream op-amp; the wiper switches introduce finite on-resistance (R_ON, ~50 Ω typical) that scales with code and can degrade CMRR/THD in precision paths. Decouple VDD/VSS with 0.1 µF ceramic capacitors placed within 5 mm of the supply pins. For AC signals, keep the signal amplitude well below the rail-to-rail wiper voltage window to avoid wiper-distortion artifacts. This page synthesizes distributor pricing, drop-in alternatives in the same TSSOP-24 package, and practical design notes not found in the manufacturer datasheet alone.
AD5206BRUZ10 - 6-Ch 10kΩ 256-Tap SPI Digital Potentiometer | ADI
The Analog Devices AD5206BRUZ10 is a 6-channel, 256-position digitally controlled variable resistor (digital potentiometer or DigiPot) with 10 kΩ end-to-end resistance per channel, communicating over a 3-wire SPI-compatible serial interface and housed in a 24-pin TSSOP (RU-24) surface-mount package. Each of the six independent RDAC channels contains a fixed resistor string with a CMOS wiper contact, providing 8-bit (256-step) resolution at ±30% nominal resistance tolerance, with power-on preset to midscale. A digital potentiometer is a solid-state semiconductor device that emulates the function of a mechanical potentiometer or variable resistor by using an array of switched resistive elements controlled through a digital interface. Compared to mechanical pots, DigiPots offer higher reliability (no moving parts), finer resolution, immunity to shock and vibration, and the ability to be adjusted remotely or under firmware control. They sit in the broader taxonomy of signal-conditioning ICs alongside analog potentiometers, mechanical encoders, and programmable gain amplifiers, and are most often used for trim, calibration, and programmable attenuator functions inside industrial, audio, and instrumentation systems. Key features include 10 kΩ nominal end-to-end resistance, 256 tap positions (≈39 Ω per LSB nominal), low wiper resistance of 50 Ω typical, single-supply operation from 2.7 V to 5.5 V or dual-supply operation from ±2.3 V to ±2.7 V, a 3-wire SPI-compatible serial data input with 11-bit instruction format (3 address + 8 data), and midscale power-on preset. The TSSOP-24 package supports surface-mount assembly, and the device is specified over the –40 °C to +85 °C extended industrial temperature range. Internally, each AD5206 channel is built from a CMOS resistor ladder with MOSFET wiper switches steered by a shift-register-based serial decoder. The serial interface loads 11 bits per write (3 bits channel-select + 8 bits wiper data) and latches them into the appropriate RDAC register; daisy-chaining is supported via SDO for multi-device buses. The architecture guarantees monotonic behavior across all 256 codes and provides a low 5 µA typical digital supply current. Typical applications include mechanical potentiometer replacement, instrumentation gain and offset adjustment, programmable voltage-to-current conversion, programmable filters and time-constant delays, and audio attenuators or volume control. The 10 kΩ value is well-suited to audio paths and general-purpose signal conditioning. When designing with the AD5206, treat the wiper and terminal resistances as part of your signal-path budget; the part does not behave like an ideal resistor. Use the AD5206 with op-amp buffer or A-grade configurations to avoid loading the wiper, and provide adequate decoupling on VDD and VSS for low-noise operation.

AD5248BRMZ50-RL7 - Dual 50kΩ 256-Tap I²C Digital Potentiometer | Analog Devices
The Analog Devices AD5248BRMZ50-RL7 is a dual-channel, 256-position, I²C-compatible digital potentiometer with 50 kΩ end-to-end resistance per channel, packaged in a compact 10-lead MSOP (3.0 mm × 4.9 mm). Each RDAC channel contains a fixed resistor string with a wiper contact that is digitally controlled through the I²C bus, providing a solid-state replacement for mechanical potentiometers in space-constrained designs. The AD5248 features dedicated AD0 and AD1 package address decode pins that allow up to four AD5248 devices to share a single I²C bus without external logic. A digital potentiometer is an integrated circuit that emulates the function of a three-terminal mechanical potentiometer using an array of resistive elements with CMOS switches. Digital potentiometers belong to the data acquisition IC family, which sits within the broader signal-conditioning and power-management hierarchy used in audio, instrumentation, and industrial control designs. Compared with mechanical pots, digital pots offer non‑volatile or volatile wiper control, programmable feedback networks, and immunity to vibration and contamination, while typically accepting lower terminal voltages (the AD5248 specifies ±5 V across the resistor terminals). Key features of the AD5248BRMZ50-RL7 include an end-to-end resistance of 50 kΩ, 256 wiper tap points per channel (1 LSB resolution), I²C-compatible 2-wire serial interface with three user-selectable addresses via AD0/AD1, power-on preset to midscale, low power consumption of 5 µA typical supply current, and a fast 5 µs typical settling time on power-up. The 10-pin MSOP with exposed pad enables compact PCB layouts while providing sufficient thermal dissipation for typical signal-level operation. Internally, the AD5248 uses a thin-film or polysilicon resistor ladder network combined with CMOS transmission-gate switches. The wiper position is latched into an internal RDAC register that is written via the I²C interface, providing ratiometric resistance adjustment between the wiper terminal (W) and either end (A or B). Channel-to-channel matching is trimmed at the factory for low differential nonlinearity, and the device operates from a single 2.7 V to 5.5 V supply. Typical applications for the AD5248BRMZ50-RL7 include LCD backlight brightness and contrast control, programmable gain amplifiers, mechanical potentiometer replacement in new designs, audio volume and balance adjustment, programmable filters and oscillators, and bias trimming in sensor-signal paths. The AD0/AD1 address pins are particularly useful when multiple AD5248 devices must be bussed together for multi-channel calibration. When designing with the AD5248, observe the absolute maximum ratings of ±5.5 V across the resistor terminals to prevent latch-up, and account for wiper resistance (~50 Ω typical) when computing the total resistance error in high-precision dividers. Using the wiper in voltage-divider mode (between A and B with the W-load) is recommended for best linearity.

AD5258BRMZ1-RL7 - 1kΩ 64-Tap I2C Nonvolatile DigiPot | ADI
The Analog Devices AD5258BRMZ1-RL7 is a nonvolatile, I²C-compatible 64-position digital potentiometer with 1 kΩ end-to-end resistance, housed in a compact 10-pin MSOP (RMZ) package. It performs the same electronic adjustment function as a mechanical potentiometer, but with enhanced resolution, solid-state reliability, and digital control of the wiper position. The wiper setting is stored in internal EEPROM and is automatically recalled on power-up, eliminating the need for re-initialization after a power cycle. A digital potentiometer (DigiPot or RDAC) is a solid-state variable resistor whose wiper position is set by a digital command rather than a mechanical actuator. DigiPots sit in the hierarchy: digital potentiometer → programmable resistor → data-conversion/peripheral IC → mixed-signal semiconductor. They replace mechanical trimmers in volume-production designs where software-driven calibration, remote adjustment, or dynamic trimming is required. Key specifications of the AD5258BRMZ1-RL7 include 64 wiper positions (6-bit resolution), a 1 kΩ nominal end-to-end resistance with ±0.1% tolerance stored in EEPROM, a 2-wire I²C-compatible serial interface, an auxiliary VLOGIC pin for mixed-voltage I/O, and software write-protect. Power-on EEPROM refresh is <1 ms, enabling rapid system startup. End-to-end resistance options in the family cover 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ. The internal architecture combines a precision thin-film resistor ladder with CMOS transmission-gate switches and a nonvolatile EEPROM shadow register. The I²C address is selectable via the AD0 pin, allowing two devices on the same bus. Per the AD5258 datasheet, current between Wiper W and Terminal B in the zero-scale state must be limited to a maximum pulse current of 20 mA to avoid degradation of the internal switch contact. Typical applications include LCD backlight brightness control, contrast and bias adjustment on displays, programmable gain amplifiers, RF power-detector calibration, audio volume control, and post-production trimming of precision sensors. Designers typically pair the AD5258 with a low-offset op-amp (e.g., AD8628) when used as an in-circuit trim element. When designing with the AD5258, add a 0.1 µF bypass capacitor close to VDD and respect the 20 mA wiper current limit. Note that DigiPots are not intended for high-current or high-voltage loads; they are optimized for signal-level adjustment and bias-setting roles in low-power analog paths. This page synthesizes distributor pricing, drop-in alternatives from the same MSOP-10 footprint family, and practical design notes that go beyond the manufacturer's datasheet, giving engineers a faster path from selection to qualified BOM line item.
AD5258BRMZ10-R7 - 10kΩ 64-Tap I2C Nonvolatile DigiPOT | ADI
The Analog Devices AD5258BRMZ10-R7 is a 10 kΩ, 64-position, nonvolatile digital potentiometer (DigiPOT) housed in a compact 10-pin MSOP package with I²C-compatible interface. It provides 1 circuit of programmable resistance from end-to-end 10 kΩ with 64 tap points, while storing the wiper position in on-chip EEPROM so settings persist through power cycles. A digital potentiometer is a solid-state replacement for a mechanical potentiometer or variable resistor. Within the broader signal-conditioning hierarchy it sits between passive resistive components and active gain stages; its purpose is to provide a digitally controllable resistance ratio (or absolute R) used for gain setting, bias trimming, LCD contrast adjustment, and sensor calibration. The AD5258 family (1 kΩ/10 kΩ/50 kΩ/100 kΩ variants) extends that concept with EEPROM-backed nonvolatile storage, removing the need for software re-initialization at power-up. Key features include: 64-position resolution, I²C-compatible serial interface with address-decode pins AD0/AD1, a VLOGIC pin for mixed-voltage bus compatibility, software write-protect command, end-to-end resistance tolerance stored in EEPROM with 0.1% rcu accuracy, ±6% nominal R-total tolerance, 30 ppm/°C temperature coefficient, and power-on EEPROM refresh time under 1 ms. The device operates from 2.7 V to 5.5 V single supply with low quiescent draw. Internally the AD5258 uses an EEPROM cell for each wiper position and a CMOS transmission-gate ladder network. Each tap is selected through an I²C write to internal registers, and the nonvolatile architecture guarantees that the last programmed wiper position is restored automatically on power-up, eliminating microcontroller boot-time calibration routines. Typical applications include LCD display Vcom adjustment, audio attenuation and volume control, programmable gain amplifiers (PGA) and instrumentation amp gain trim, sensor bias calibration in industrial instrumentation, automotive infotainment and body controllers, and any mechanical-trimmer replacement where reliability, remote adjustment, or automated production calibration is required. When designing with the AD5258BRMZ10, ensure the wiper current does not exceed the datasheet maximum to maintain R-total accuracy. Use the VLOGIC pin when interfacing to 1.8 V or 3.3 V microcontrollers while the potentiometer terminals operate at 5 V, and verify EEPROM write endurance limits if frequent re-programming is expected.

AD5258BRMZ100 - 100kΩ 64-Tap I2C Nonvolatile DigiPot | ADI
The Analog Devices AD5258BRMZ100 is a nonvolatile, I²C-compatible 64-position digital potentiometer with 100 kΩ end-to-end resistance, supplied in a 10-pin MSOP (RM suffix) surface-mount package. It integrates EEPROM-backed wiper memory, two address-decoded AD0 pins (supporting up to four devices on one bus), and a separate VLOGIC pin for flexible logic-level interfacing between 2.7 V and 5.5 V domains. A digital potentiometer (DigiPOT) is a solid-state, electronically-controlled variable resistor that replaces a mechanical trimpot. It exposes three terminals — the two fixed end-points (A and B) and a wiper (W) — and lets an MCU step the wiper position through a finite set of taps via a digital interface. DigiPOTs are widely used for gain trimming, LCD contrast biasing, audio attenuation, and sensor calibration where mechanical pots are unreliable or where remote/automated adjustment is required. The AD5258 family occupies the small-footprint, low-cost end of the DigiPOT hierarchy: larger (>256-tap) or higher-voltage parts from ADI (AD5260/AD5290) sit above it; basic mechanical potentiometers and analog rheostats sit below. Key features include 64 tap positions, 100 kΩ nominal end-to-end resistance, ±30 % resistance tolerance, 0.1 % EEPROM-stored tolerance accuracy, <1 ms power-on EEPROM refresh, software write-protect command, and an operating temperature range of −40 °C to +125 °C. The MSOP-10 footprint is only 3 mm × 4.9 mm, making it one of the smallest nonvolatile DigiPOTs on the market. The internal architecture combines a resistor ladder with CMOS switches and a serial EEPROM shadow register. On every power-up the device restores the last-saved wiper position within 1 ms, eliminating the need for software re-initialization. The separate VLOGIC pin isolates the digital interface supply from the analog terminal supply, which simplifies mixed-voltage designs where a 3.3 V MCU controls a 5 V analog rail. Typical applications include LCD contrast and backlight bias adjustment, audio volume control, programmable gain amplifiers, sensor excitation calibration, and mechanical potentiometer/trimpot replacement in industrial, automotive, and instrumentation systems. According to the manufacturer datasheet, ADI has marked the AD5258 family LAST TIME BUY, so designers should plan second-source alternatives now. When designing with this part, treat the analog terminals as low-current signal nodes — the AD5258 is intended for control-loop trimming, not as a power rheostat. Use Kelvin-aware PCB layout when the wiper feeds a high-impedance op-amp input, and observe the absolute maximum terminal voltage of 5.5 V even when the device is unpowered. This page consolidates distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving a single reference point for AD5258BRMZ100 sourcing.

According to the ADI AD5272/AD5274 datasheet, the device integrates industry-leading variable resistor performance with 50-times-programmable (50-TP) nonvolatile memory (NVM), allowing the wiper position to retain its setting across power cycles. A digital rheostat (sometimes called a digital potentiometer or digipot) is a solid-state replacement for a mechanical potentiometer, providing a programmable two-terminal variable resistor that is controlled through a digital serial bus. It belongs to the broader family of programmable analog ICs sitting between passive components (resistors) and full data-acquisition chains, and is widely used where mechanical trimming is impractical: in calibration, gain setting, sensor linearization, and bias adjustment. Key features include 1024 tap points, 1% end-to-end resistor tolerance error, a 2.7 V to 5.5 V single-supply operating range, an I2C-compatible 2-wire serial interface supporting both standard (100 kHz) and fast (400 kHz) modes, and 50-times programmable nonvolatile memory with read-back. The rheostat mode (terminal W to terminal A or B) supports unipolar signal swing, and the device includes power-on preset to midscale. In terms of architecture, the AD5272 uses a CMOS resistor-array structure with a wiper that is digitally addressed and latched into NVM via the I2C bus. The 50-TP architecture provides a controlled write budget to ensure long-term data retention in EEMEM. Compared with purely volatile digipots, the integrated EEMEM eliminates the need for an external EEPROM and a separate programming step on every power-up. Typical applications include mechanical potentiometer replacement, instrumentation gain adjustment, programmable voltage-to-current conversion, laser-trim replacement, and RF attenuator biasing. The combination of 1% resistor tolerance and 50-TP NVM makes the part especially attractive where calibration is performed once at production and then re-used across multiple power cycles. When designing with the AD5272, observe the absolute-maximum terminal voltages (Vdd + 0.3 V and -0.3 V on W/A/B). For ac-coupled or bipolar signals, bias the rheostat inside the supply headroom. For best noise performance, use the lower-resistance variants or connect an external resistor in parallel only when the design explicitly accounts for the resulting ratiometric error.
