13-Bit Differential Input, Low Power A/D Converter With SPI Serial Interface

MCP3304 The Microchip Technology Inc. MCP3302 MCP3304 13-bit A/D converters feature full differential inputs and low power consumption in a small package that is ideal for battery powered systems and remote data acquisition applications. The MCP3302 is programmable to provide two differential input pairs or four single ended inputs. The MCP3304 is programmable and provides four differential input pairs or eight single ended inputs. Incorporating a successive approximation architecture with on-board Sample and Hold circuitry, these 13-bit A/D converters are specified to have 1 LSB Differen tial Nonlinearity (DNL); 1 LSB Integral Nonlinearit (INL) for B-grade and 2 LSB for C-grade devices. Th industry-standard SPI serial Interface enables 13-bit , A/D converter capability to be added to any PIC Microcontroller By Microchip Technology Inc.
