The MCP3004/3008 is a 10-bit analog-to-digital converter from Microchip Technology Inc. with on-board sample and hold circuitry. It features 4 (MCP3004) or 8 (MCP3008) input channels, which can be programmed as single-ended or pseudo-differential pairs. The devices support SPI serial interface and operate on a single supply voltage range of 2.7V - 5.5V. The maximum sampling rate is 200 ksps at VDD = 5V and 75 ksps at VDD = 2.7V. The MCP3004/3008 are available in PDIP, SOIC and TSSOP packages.
The MCP3004 and MCP3008 devices are successive‑approximation 10‑bit analog‑to‑digital converters with SPI serial interface. The MCP3004 provides four single‑ended inputs (or two pseudo‑differential pairs) while the MCP3008 offers eight single‑ended inputs (or four pseudo‑differential pairs). They are available in PDIP, SOIC and TSSOP packages and are intended for sensor interfacing, data acquisition, and battery‑operated systems.
Key electrical characteristics include a supply range of 2.7 V‑5.5 V, standby current as low as 5 nA, active current up to 500 µA at 5 V, and sampling rates up to 200 ksps (5 V) or 75 ksps (2.7 V). The devices operate over an industrial temperature range of –40 °C to +85 °C and meet the specified DNL/INL limits of ±1 LSB.
