The Microchip MCP300X family of 10-bit analog-to-digital
converters (ADCs) combines high performance and low
power consumption in a small package making it ideal
for embedded control applications.
Consisting of the MCP3001, MCP3002, MCP3004 and
MCP3008, the MCP300X family features a successive
approximation register (SAR) architecture and an industry-
standard SPI
TM
serial interface. Devices are available with
1, 2, 4 or 8 input channels and in PDIP, SOIC and TSSOP
packages.
The MCP300X family offers existing Microchip customers
added flexibility when incorporating analog inputs into
their designs. The industry standard SPI interface allows
10-bit ADC capability to be added to any PICmicro®
microcontroller. In addition, new customers will find the
performance and price of the MCP300X family very
attractive.
Applications for the MCP300X family 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.
