MICROCHIP MCP3302 Manuals

MCP3302/04 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 Differential Nonlinearity (DNL); ±1 LSB Integral Nonlinearity (INL) for B-grade and ±2 LSB for C-grade devices. The industry-standard SPI™ serial interface enables 13-bit A/D converter capability at up to 100 ksps sampling rate.

This document introduces the features and characteristics of Microchip Technology Inc. MCP3302/04 13-bit A/D converters, including full differential inputs, single/differential inputs, ±1 LSB maximum DNL, ±1 LSB maximum INL, single supply operation, 100 ksps sampling rate, 50 nA typical standby current, 450 µA maximum operating current, industrial temperature range, etc.
