Overview

The MCP3002-I/SN is a 10-bit Successive Approximation Register (SAR) Analog-to-Digital Converter that features two channels and an SPI serial interface. It is designed to provide high performance in a compact 8-SOIC package, operating over a voltage range of 2.7V to 5.5V. This ADC is particularly effective for space-constrained applications requiring low power consumption, drawing only 525uA at 5V and 5uA during standby.

Why Choose This Part

The MCP3002 offers a small 8-pin SOIC footprint which saves significant PCB real estate compared to higher pin-count ADCs. It provides flexibility with programmable single-ended or pseudo-differential input pairs while maintaining low power operation across its entire 2.7V to 5.5V supply range.

Applications

Sensor Interface
Converting analog signals from industrial sensors into digital data for microcontrollers with limited built-in ADC capabilities.
Battery Operated Systems
Utilizing the low 5uA standby current to prolong battery life in portable measurement devices.
Process Control
Monitoring voltage levels in automation loops where 10-bit resolution provides sufficient precision.
Data Acquisition
Collecting dual-channel analog data in compact embedded systems using a high-speed SPI interface.

Getting Started

To begin development, interface the MCP3002 with any MCU supporting SPI mode 0,0 or 1,1. Ensure a stable reference voltage is provided as the device uses VDD as its reference. For prototyping, the MCP3002 is available in breadboard-friendly DIP packages, though the SOIC version is standard for production.
