MCP3004-I/SL
MCP3004-I/SL - 10-Bit 4-Channel 200kSPS ADC | Microchip
Microchip Technology MCP3004-I/SL is a 10-bit, 4-channel, 200kSPS successive-approximation analog-to-digital converter with an SPI interface, supplied in a 14-pin SOIC package. The converter supports 4 single-ended inputs or 2 differential inputs and combines low power consumption with a compact surface-mount footprint. Its 10-bit resolution provides 1,024 possible output codes, making it suitable for embedded control, industrial sensing, temperature measurement, potentiometer monitoring, and other moderate-resolution acquisition systems.
An ADC is an interface IC that converts an analog voltage into a digital value for processing, storage, or control. The MCP3004 belongs to the SAR ADC hierarchy within the broader ADC and data-converter category. Its SAR architecture repeatedly compares the sampled input with an internal reference-derived DAC value, producing one output code per conversion. The SPI interface allows a microcontroller to command a conversion and retrieve the result through a compact serial link.
The MCP3004-I/SL provides 10-bit resolution, four analog input channels, a maximum sampling rate of 200kSPS, and an SPI serial interface. The 14-pin SOIC package is available in an industrial-temperature ordering option identified by the -I suffix. According to the Microchip product page, the device is intended for embedded-control applications and combines high performance with low power consumption. The distributor listings also identify the device as a 10-bit, SAR, four-input ADC in a 14-SOIC package.
Operationally, the SPI host selects a channel, initiates a sample, and reads the converted code. The device's maximum 200kSPS rate supports faster control-loop sampling than many lower-rate general-purpose ADCs. Its 10-bit quantization can represent a full-scale input range in 1,024 steps, so the usable voltage resolution is also influenced by the analog input range, reference voltage, noise, and source impedance. Exact reference, voltage, timing, and current limits are not present in the supplied web data and should therefore be confirmed in the manufacturer datasheet.
Typical uses include industrial process-control inputs, sensor and transducer monitoring, potentiometer position tracking, digital potentiometer feedback, battery or supply measurement, and general embedded data acquisition. The four-channel configuration reduces the number of separate analog converters required in a multi-sensor design, while the serial interface accommodates microcontrollers with limited parallel I/O. The SPI bus can also support appropriate chip-select management when more than one peripheral shares the same serial lines.
The principal design consideration is analog signal conditioning. Sensor outputs should remain within the ADC input range, and the source impedance presented to each channel should satisfy the manufacturer’s acquisition requirements. Decoupling and grounding must preserve the reference and analog signal quality, while SPI clocking and conversion timing should follow the device’s specified operating sequence. Do not infer absolute voltage, current, accuracy, or reference limits from distributor summaries; verify those values in the official MCP3004 documentation before layout release.
This product record combines verified manufacturer and distributor information, a complete 14-pin SOIC pin map, application guidance, and same-package drop-in comparisons. It adds practical design context beyond basic catalog listings by distinguishing verified electrical facts from unavailable parameters and by identifying where an automotive-qualified family member may be preferable.
