MCP3004 — Datasheet Summary, Specs & Alternatives

01 — Overview

This Microchip datasheet covers the MCP3004 and MCP3008, 10-bit successive approximation analog-to-digital converters. Designed for sensor interfaces, process control, and data acquisition, these devices feature on-chip sample-and-hold circuitry and an SPI serial interface. Key parameters include 10-bit resolution with ±1 LSB max DNL and INL, a maximum conversion rate of 200 ksps at 5V, and low power consumption with typical active currents around 300 µA. Both parts operate on a single supply of 2.7V to 5.5V and are available in automotive-qualified packages ranging from -40°C to +125°C.
