Microchip MCP3008 10-Bit ADC, 8-Channel SPI, 2.7V, 16-DIP

The Microchip MCP3008 is a highly versatile, successive approximation 10-bit analogue-to-digital converter (ADC) featuring integrated sample-and-hold circuitry. This device offers significant flexibility in signal acquisition, as it can be programmed to operate with either eight single-ended inputs or four pseudo-differential input pairs, making it suitable for a wide array of measurement scenarios. Communication is handled via a straightforward serial interface that is fully compatible with the widely-used SPI protocol, ensuring easy integration into most microcontroller-based systems.

Engineered with low-power CMOS technology, the MCP3008 is an efficient choice for power-sensitive applications. It delivers reliable performance with a maximum sampling rate of 200 kSPS, providing a solid balance of speed and precision for many sensing and control tasks. The converter is specified with excellent linearity, featuring a maximum Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) of just ±1 LSB.
