MCP3002-I/SN - 10-Bit 2-Channel 200ksps SAR ADC | Microchip
MPN: MCP3002-I/SN ✓ ActiveMCP3002-I/SN Overview
An ADC is an analog-to-digital converter, a category of interface IC that converts continuous voltage signals into numeric values for processing by a microcontroller, DSP, or other digital controller. The MCP3002 belongs to the SAR ADC family, using successive approximation to determine each conversion result. This architecture is well suited to embedded measurement and control because it provides predictable sampling operation, an SPI interface, low power consumption, and a small package.
The verified product information identifies a resolution of 10 bits, two analog input channels, and a maximum sampling rate of 200 ksps. Its SPI serial interface allows the converter to communicate efficiently with a host controller using serial clock, data, and chip-select signals. The MCP3002-I/SN is also identified as an AEC-Q100 automotive-grade option, while its 8-pin SOIC package supports conventional surface-mount assembly.
Because the MCP3002 uses a single ADC with two input channels, the available measurements must be scheduled by the host controller. The SAR conversion process and on-board sample-and-hold circuitry support acquisition of changing analog signals, while the 10-bit format provides 1,024 possible digital codes. Exact input ranges, conversion timing, reference-voltage limits, and channel input impedance were not included in the supplied verified records and should be confirmed in the manufacturer datasheet before final circuit design.
Typical uses include industrial sensor interfaces, automotive control modules, potentiometer monitoring, temperature-sensor measurement, and general embedded data acquisition. In each case, the MCP3002 can convert one or two analog voltage inputs into serial data for a microcontroller or other controller. The 200 ksps rate is especially useful for higher-speed monitoring than typical slow sensor channels require.
When laying out a circuit, place the converter close to the analog source and route the SPI signals away from noisy switching nodes. Provide a clean reference and supply arrangement, and verify that the selected input range supports the sensor voltage. Confirm the pinout and pin numbers in the official Microchip datasheet before PCB release, because the supplied search records did not provide a verifiable pin-by-pin assignment.
This product record combines the verified manufacturer description, distributor specifications, package information, AEC-Q100 designation, current distributor pricing, and practical ADC selection guidance. It also distinguishes verified facts from parameters that still require datasheet confirmation, helping engineers evaluate the MCP3002-I/SN without relying on unverified substitutions.

Typical Applications
MCP3002-I/SN is suitable for 6 applications: Automotive Sensor Acquisition, Industrial Control Module, Temperature Sensor Interface, Potentiometer Position Measurement, Battery-Powered Embedded Monitor, General Embedded Data Acquisition.
Automotive Sensor Acquisition
The MCP3002-I/SN fits automotive sensor acquisition because it combines two analog input channels with 10-bit resolution, a 200 ksps sampling rate, and an AEC-Q100 designation verified by Arrow. A microcontroller can initiate conversions through the SPI interface and use the resulting data for monitoring or closed-loop control. The 8-pin SOIC package helps limit board area, while the 2.7 V operating point supports compact embedded systems. Because the supplied records do not specify the complete input range or automotive temperature grade, engineers must verify those limits in the official 21294E datasheet before release.
Recommended
Industrial Control Module
The MCP3002-I/SN is appropriate for industrial control modules that monitor two external analog signals using a compact serial ADC. Its 10-bit SAR architecture, 200 ksps conversion rate, and SPI interface allow a host controller to acquire data without occupying many parallel I/O pins. This is useful for pressure, position, or analog control feedback where moderate resolution and compactness are priorities. The verified data does not provide input impedance, reference limits, or operating temperature, so signal conditioning and environmental suitability must be confirmed from the manufacturer datasheet.
Recommended
Temperature Sensor Interface
The MCP3002-I/SN can digitize the output of a temperature sensor when the sensor signal is conditioned into the converter's permitted input range. Two channels allow a controller to monitor temperature and a second process variable using the same SPI connection. The 10-bit result provides 1,024 discrete code levels, while the 200 ksps capability offers margin beyond typical thermal measurement bandwidth. Exact input voltage, reference accuracy, and conversion timing are not present in the supplied records, so designers should confirm them before setting gain and resolution assumptions.
Recommended
Potentiometer Position Measurement
The MCP3002-I/SN is well matched to potentiometer and position feedback systems that require two sampled analog voltages in a compact embedded design. One channel can represent the position signal while the other can monitor a reference or complementary feedback signal. The SAR ADC samples through on-board sample-and-hold circuitry and reports results over SPI, allowing the controller to calculate position or detect movement. Verify the allowable input range, source impedance, and acquisition timing in the manufacturer datasheet because these values were not supplied in the verified search records.
Recommended
Battery-Powered Embedded Monitor
The MCP3002-I/SN can serve as the measurement front end in a compact battery-powered monitor because its verified 10-bit, two-channel capability and SPI interface minimize the number of data lines required from the host controller. It is appropriate for monitoring slow-changing analog levels rather than waveform capture beyond the converter's stated 200 ksps rate. The manufacturer describes the device as combining high performance with low power consumption, making it a candidate for embedded sensing, although exact current consumption, shutdown behavior, and voltage limits must be verified in the official datasheet.
Recommended
General Embedded Data Acquisition
The MCP3002-I/SN supports general embedded data-acquisition designs requiring two analog channels, 10-bit resolution, and a serial connection to a controller. Its 8-pin SOIC package simplifies PCB routing relative to a wide parallel ADC, while the 200 ksps sampling rate supports comparatively rapid control-loop updates. It can be used in instrumentation, educational electronics, and compact control boards where SPI is already available. The source records do not specify channel multiplexing details, input impedance, or complete timing parameters, so these should be checked before acquisition timing is committed.

Design Notes
Route the analog input traces as short and direct as practical, and keep them away from SPI clock edges and high-current switching paths. Place any input filtering or buffering components close to the MCP3002 pins so that unwanted coupling is not introduced between the sensor and the converter. Because the supplied verified records do not specify input impedance or permitted input range, confirm those values in the official 21294E datasheet before selecting resistor or capacitor values.
Treat SPI clock, chip-select, and data lines as a compact synchronous interface driven by the host controller. Keep the clock trace short, provide a continuous ground reference, and avoid routing it in parallel with analog input wiring for unnecessary coupling. The MCP3002-I/SN uses on-board sample-and-hold circuitry, but the exact acquisition interval and conversion timing must be taken from the manufacturer datasheet when calculating the required command and sample sequence.
Do not infer the complete analog input range, reference-voltage limits, or pin assignments from distributor category labels. The supplied records establish a 2.7 V device with two analog channels, but they do not provide the detailed electrical tables or verified pin map. Before schematic release, cross-check power pins, ground pins, analog inputs, SPI signals, reference requirements, and decoupling recommendations against the official Microchip 21294E PDF.
Compliance Information
The verified Arrow listing identifies MCP3002-I/SN as AEC-Q100 automotive. The supplied records do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status.
