The MCP3004/3008 devices are successive approximation 10-bit Analog-to-Digital (A/D) converters with on-board sample and hold circuitry. The MCP3004 is programmable to provide two pseudo-differential input pairs or four single-ended inputs. The MCP3008 is programmable to provide four pseudo-differential input pairs or eight single-ended inputs. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are specified at ±1 LSB. Communication with the devices is accomplished using a simple serial interface compatible with the SPI protocol. The devices are capable of conversion rates of up to 200 ksps. The MCP3004/3008 devices operate over a broad voltage range (2.7V - 5.5V). Low current design permits
The MCP3004 and MCP3008 are 10‑bit successive‑approximation analog‑to‑digital converters with SPI serial interface. The MCP3004 provides four single‑ended or two pseudo‑differential inputs, while the MCP3008 offers eight single‑ended or four pseudo‑differential inputs. Both devices operate from a single supply of 2.7 V to 5.5 V and feature on‑chip sample‑and‑hold circuitry.
Key performance figures include up to 200 ksps conversion rate at 5 V, 75 ksps at 2.7 V, typical standby current of 5 nA, and active current of about 500 µA. The converters are available in PDIP, SOIC and TSSOP packages and are rated for industrial temperature range –40 °C to +85 °C.
