ADC10158CIN/NOPB 概要
An SAR (Successive Approximation Register) ADC is a type of data converter that resolves each conversion in N clock periods by switching capacitor weights in a binary-search sequence. SAR ADCs occupy the middle of the speed-resolution triangle - slower than flash and pipeline converters but offering 10-18 bit resolution with zero pipeline latency, making them ideal for multi-channel data-acquisition systems, industrial control, and instrumentation front-ends. The ADC10158 sits within the data-acquisition IC family, which bridges the analog input stage (sensor/MUX) and the digital processing stage (microcontroller/DSP/FPGA).
Key features of the ADC10158CIN/NOPB include 10-bit resolution plus sign (effective 11-bit dynamic range when signed), 8 single-ended input channels, an on-chip track/hold, a successive-approximation architecture, and an industry-standard parallel output for direct connection to 8/16-bit microprocessors. The /NOPB suffix denotes a lead-free (No Pb) finish that is RoHS-compliant. Through-hole 28-DIP packaging simplifies prototyping, breadboarding, and legacy PCB repair where SMD footprints are not available.
The architecture uses a charge-redistribution DAC with binary-weighted capacitors and a precision comparator; the SAR logic iterates from MSB to LSB until the input voltage is resolved to within the 10-bit LSB step. The analog front-end MUX is low-leakage CMOS with break-before-make switching to prevent channel-to-channel crosstalk during sequential sampling.
Typical applications include multi-channel industrial data-acquisition boards, portable instrumentation front-ends, process-control analog input modules, and embedded sensor-reading subsystems. The 28-DIP form factor also makes the ADC10158 a popular choice for educational labs, hobbyist retrocomputing projects, and legacy repair.
When designing with this device, place a 10 uF (tantalum or ceramic) decoupling capacitor on the +5 V AVDD pin within 1 cm of the package, plus a 0.1 uF ceramic high-frequency bypass. The reference pin requires a low-impedance source - a 10 uF + 0.1 uF pair is typical. Avoid routing digital outputs adjacent to analog input traces on the PCB.

主な用途
ADC10158CIN/NOPB の用途: 6 件s: Industrial Multi-Channel Data Acquisition Systems, Portable Battery-Powered Instrumentation, Process Control Analog Input Modules, Embedded Sensor Reading Subsystems, Legacy PCB Repair and Retrocomputing Projects, Test and Measurement Equipment Front-Ends.
Industrial Multi-Channel Data Acquisition Systems
The ADC10158CIN/NOPB's integrated 8-channel analog multiplexer and 10-bit plus-sign SAR architecture are ideal for industrial PLCs, distributed control systems (DCS), and panel meters that must monitor many process sensors (4-20 mA loops, 0-10 V transducer outputs, RTD-conditioned signals). The 28-DIP through-hole form factor simplifies assembly on legacy I/O cards that use plated-through-hole pads, and the parallel microprocessor-compatible output bus drops directly onto an 8051, PIC, or 80C186 data bus without a glue logic layer. The single +5 V supply aligns with industrial 5 V backplane rails, eliminating the need for a separate analog LDO. The on-chip track-and-hold and break-before-make MUX switching keep channel-to-channel settling errors under one LSB at the datasheet's recommended operating point.
おすすめ
Portable Battery-Powered Instrumentation
The ADC10158CIN/NOPB operates from a single +5 V supply drawing low operating current, making it suitable for handheld digital multimeters, portable data loggers, and field-calibration instruments where battery life is critical. The single +5 V rail simplifies power tree design - a single boost converter can derive the analog and digital supply. The DIP-28 package is friendly to hand-soldering for prototype builds and one-off repair of legacy portable test equipment. The 10-bit plus-sign resolution (1024 + sign codes = 2048 effective codes) gives ~0.05% step resolution, which is sufficient for most process-control transducer readouts, though 12-bit ADCs (e.g., AD7798) are preferred for precision lab work.
おすすめ
Process Control Analog Input Modules
The ADC10158CIN/NOPB is a classic choice for rack-mounted process-control analog input modules that aggregate 4-8 process variables (temperature, pressure, flow, level) per board. The integrated MUX eliminates an external 8:1 analog switch (saving BOM cost and board space), and the SAR architecture gives deterministic single-shot conversion latency - critical for closed-loop PID control where pipeline delay from a sigma-delta or pipelined ADC would complicate loop tuning. The 5 V supply and industrial -40 C/+85 C operating range are well-matched to DIN-rail I/O modules and PLC backplanes. Parallel output drops straight into the module's microcontroller data bus without DMA complexity.
おすすめ
Embedded Sensor Reading Subsystems
In embedded sensor-reading applications, the ADC10158CIN/NOPB's 8-channel MUX and parallel output reduce the cost-per-sensor-channel to under $1 per channel (at 1k qty), well-suited for HVAC controllers, building-automation sensors, and appliance control boards. The 28-DIP through-hole package is also widely used in educational lab kits and university embedded-systems courses, because students can breadboard and probe every signal pin. The /NOPB lead-free finish meets modern RoHS requirements for consumer and industrial end products shipped into the EU.
おすすめ
Legacy PCB Repair and Retrocomputing Projects
The ADC10158CIN/NOPB's 28-DIP through-hole footprint makes it the de-facto replacement part for legacy 1990s-era ISA-bus data-acquisition cards, retrocomputing audio interfaces, and legacy instrumentation front-ends. The DIP-28 package is breadboard-compatible and socket-compatible, which simplifies field repair without PCB rework. Hobbyist retrocomputing and vintage-computer restoration projects (e.g., vintage synthesizer CV-to-digital boards) commonly use the ADC10158 because it is still actively produced by the manufacturer and stocked at major distributors. Same-die compatibility with the through-hole and SMD variants (PDIP-28 and SOIC-28) preserves the option to upgrade an existing board to SMD without firmware changes.
おすすめ
Test and Measurement Equipment Front-Ends
Bench-top digital multimeters, oscilloscope front-end signal-conditioning boards, and laboratory data-logging front-ends commonly use the ADC10158CIN/NOPB because of its deterministic single-shot SAR latency, integrated 8-channel MUX, and 5 V single-supply operation. The 10-bit plus-sign resolution gives 11-bit effective dynamic range (~66 dB) - sufficient for general-purpose bench instrumentation though not for high-precision metrology. The 28-DIP package simplifies fixture-based calibration since the IC can be socketed and replaced without desoldering.

設計ノート
The ADC10158CIN/NOPB requires a low-noise +5 V analog supply (AVDD) separate from the noisy digital +5 V (DVDD). Tie both supplies to the same +5 V rail at the PCB entry point (single LDO output), and decouple each AVDD/DVDD pin with a 10 uF tantalum + 0.1 uF ceramic pair placed within 1 cm of the pin. Estimated: at 5 V supply drawing typical 10 mA, each supply pin dissipates ~50 mW - no thermal concerns even in the 28-DIP package.
Route analog input traces (CH0-CH7) and the REF input on a separate inner layer isolated by AGND/DGND planes. Keep digital output bus traces (D0-D9, RD, WR, CS) on the opposite side of the PCB and never cross analog traces. Place the reference bypass capacitor on pin 11 within 5 mm of the package; a 10 uF + 0.1 uF pair is typical per TI datasheet recommendations. Avoid running digital traces parallel to analog traces for more than 10 mm - cross only at 90-degree.
Do not omit the reference bypass capacitor on pin 11 - the ADC will oscillate or exhibit excessive INL without it. Do not apply analog inputs above AVDD + 0.3 V or below AGND - 0.3 V, as the input ESD diodes will forward-conduct and degrade the channel. Do not leave the MCMC chip select (CS) pin floating - tie it inactive (logic high) for the unused ADC state. Estimated: when reading through 8 sequential channels at full throughput, the worst-case channel-to-channel settling error is approximately 1 LSB if the MCMC settling time meets the datasheet specification.
