ADC102S101CIMMX/NOPB 概要
A successive-approximation ADC is a sampled-data converter that uses a binary-search algorithm and an internal capacitive charge-redistribution DAC to digitize an analog input one bit per clock cycle. SAR ADCs deliver deterministic latency, no-pipeline delay, and excellent dynamic performance for multiplexed multi-channel systems, which is why they dominate industrial instrumentation, motor control, and precision-sensor front ends. The ADC102S101 places two single-ended input channels behind an internal 2-to-1 analog mux, allowing a single serial interface to serve two sensors with deterministic per-channel acquisition.
Key features include 10-bit resolution, 1 Msps maximum throughput, single 2.7 V to 5.25 V analog supply, low power consumption, an external reference option, and a shutdown mode that reduces current to microampere levels. The high-speed serial interface is compatible with SPI, QSPI, MICROWIRE and many DSP serial ports, allowing direct connection to microcontrollers and DSPs without glue logic. An external reference pin lets designers trade noise and scale for their analog input range, while internal sequencing keep single-shot logic simple.
The 8-lead VSSOP (also known as MiniSOIC or MSOP) footprint is one of the smallest 8-pin SAR ADC packages available, and the industrial -40 °C to +85 °C rating supports factory-floor deployment. Designers should ensure the analog and digital grounds are joined at a single point near the converter, and that the input bandwidth and source impedance obey the datasheet's acquisition-time equations to avoid codes-dependent distortion.
Typical applications include portable battery-powered instrumentation, industrial process control and PLC analog front ends, automotive sensor signal conditioning (non-safety), optical-sensor modules, and consumer audio/sensor signal acquisition. Decoupling should follow the typical-application section of the datasheet, with a 1 µF plus 0.1 µF combination on the supply pin and short, symmetric analog-trace routing to both input channels.

主な用途
ADC102S101CIMMX/NOPB の用途: 6 件s: Portable Battery-Powered Instrumentation, Industrial Process Control and PLC Analog Front Ends, Optical-Sensor Signal Acquisition Modules, Automotive Sensor Signal Conditioning (Non-Safety), Consumer Audio and Sensor Signal Acquisition, Data-Acquisition Cards and PC Peripherals.
Portable Battery-Powered Instrumentation
The ADC102S101CIMMX/NOPB suits portable, battery-powered instrumentation thanks to its 2.7 V to 5.25 V single-supply operation, 3.9 mW typical power at 3 V, and microampere-level shutdown mode. The 8-VSSOP footprint occupies only 3.00 mm x 3.00 mm on the PCB, enabling dense handheld designs. Its 500 ksps to 1 Msps SAR architecture delivers deterministic, no-latency conversions suitable for sensor signal acquisition behind a low-power MCU. Battery life is extended by issuing the SHUTDOWN command between scans, dropping supply current to the microampere range.
おすすめ
Industrial Process Control and PLC Analog Front Ends
For industrial process-control and PLC analog front ends, the ADC102S101CIMMX/NOPB offers 10-bit resolution with two single-ended input channels at up to 1 Msps, sufficient for multiplexed transducer monitoring. The -40 °C to +85 °C industrial temperature rating supports factory-floor deployment. The SPI/QSPI/MICROWIRE-compatible serial interface allows direct connection to PLC host processors and industrial MCUs. Designers commonly pair it with op-amp signal-conditioning front ends to scale 4-20 mA or 0-10 V field signals into the 0 V to VREF input range of the converter.
おすすめ
Optical-Sensor Signal Acquisition Modules
Optical-sensor modules for ambient-light, proximity, or color sensing benefit from the two-channel input of the ADC102S101CIMMX/NOPB, allowing simultaneous digitization of two photodiode currents via transimpedance amplifiers. The SAR architecture provides single-shot, deterministic conversions with no pipeline delay, which is essential for synchronized optical measurements. The 10-bit resolution is adequate for light-level metering in display-brightness control, industrial color sorting, and reflective sensor front ends. The 8-VSSOP footprint enables integration into compact optical modules.
おすすめ
Automotive Sensor Signal Conditioning (Non-Safety)
For non-safety automotive sensor-conditioning applications such as body-control modules, HVAC controls, and ambient sensors, the ADC102S101CIMMX/NOPB provides two 10-bit channels at 1 Msps on a 5 V rail, well-matched to typical automotive sensors. The device is specified for -40 °C to +85 °C and operates over 2.7 V to 5.25 V, accommodating 5 V vehicle buses. Designers should follow the manufacturer's recommended decoupling network (1 µF plus 0.1 µF on AVDD) and route analog and digital grounds to a single star-point near the converter for robust EMI performance.
おすすめ
Consumer Audio and Sensor Signal Acquisition
In consumer audio and sensor front ends, the ADC102S101CIMMX/NOPB digitizes low-bandwidth audio or sensor signals at 10-bit resolution and up to 1 Msps, suiting volume-control knobs, audio level meters, and microphone signal chains. The SPI-compatible serial interface glues directly to audio DSPs or microcontrollers without glue logic. The two single-ended channels enable stereo or dual-sensor acquisition from a single converter, reducing BOM cost. The microampere shutdown mode supports battery-powered headphones and portable speakers.
おすすめ
Data-Acquisition Cards and PC Peripherals
The ADC102S101CIMMX/NOPB integrates well into USB-connected DAQ cards and PC peripherals where two analog channels at 10 bits and 1 Msps provide enough throughput for general-purpose measurement of temperature, voltage, or vibration transducers. The SPI digital interface bridges easily to USB-to-SPI bridge ICs and FPGAs, allowing PC-side data logging. Its small 8-VSSOP footprint and single 3.3 V or 5 V supply simplify mixed-signal PCB layout. The external reference pin lets designers calibrate full-scale to system voltage standards.

設計ノート
Decouple VA (analog supply) with a 1 µF bulk plus a 0.1 µF ceramic placed as close as possible to the VA and GND pins. The reference pin (REF) should be decoupled with a 10 µF plus 0.1 µF combination per the datasheet typical-application circuit. Avoid sharing VA with high-current digital loads; place a small ferrite bead between analog and digital rails when the same 5 V source powers both.
Route analog input traces IN1 and IN2 as short, symmetric pairs to minimize channel-to-channel skew and common-mode pickup. Connect the analog and digital grounds at a single star-point beneath the converter (or under the GND pin) to avoid digital return currents flowing through the analog ground trace. Keep SCLK and DOUT traces away from IN1 and IN2 to prevent digital switching noise from degrading SNR.
Do not leave REF floating or tied to VA without the datasheet decoupling - the ADC ratiometric performance depends on a clean reference. Observe the minimum acquisition time tACQ for your source impedance; high-impedance sources require an input buffer. The SHUTDOWN pin (where present) must be driven high for normal operation or left floating only if the datasheet explicitly allows it. Verify the maximum SCLK rate against your sample-rate requirement.
