Description

MCP3002 10-bit Analog-to-Digital Converter (ADC) combines high performance and low power consumption in a small package, making it ideal for embedded control applications. The MCP3002 features a successive approximation register (SAR) architecture and an industry-standard SPI? serial interface, allowing 10-bit ADC capability to be added to any PICmicro? microcontroller. The MCP3002 features 200k samples/second, 2 input channels, low power consumption (5nA typical standby, 520A typical active), and is available in 8-pin PDIP, SOIC and TSSOP packages. Applications for the MCP3002 include data acquisition, instrumentation and measurement, multi-channel data loggers, industrial PCs, motor control, robotics, industrial automation, smart sensors, portable instrumentation and home medical appliances.

The Microchip Technology Inc. MCP3002 is a successive approximation 10-bit Analog-to-Digital (A/D) Converter with on-board sample and hold circuitry. The MCP3002 is programmable to provide a single pseudo-differential input pair or dual single-ended inputs. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are both specified at ±1 LSB. Communication with the device is done using a simple serial interface compatible with the SPI protocol. The device is capable of conversion rates of up to 200ksps at 5V and 75ksps at 2.7V. The MCP3002 device operates over a broad voltage range (2.7V - 5.5V). Low current design permits operation with a typical standby current of 5nA and a typical active current of 375A. The MCP3002 is offered in 8-pin PDIP, TSSOP and 150mil SOIC packages.
