Incorporating a successive approximation architecture with on-board sample and hold circuitry, the 13-bit A/D converter is specified to have ±1 LSB Differential Nonlinearity (DNL) and ±1 LSB Integral Nonlinearity (INL) for B-grade devices and ±2 LSB for C-grade devices. The industry-standard SPI serial interface enables 13bit A/D converter capability to be added to any PIC® microcontroller. The MCP3301 features a low current design that permits operation with typical standby and active currents of only 50 nA and 300 µA, respectively. The device is capable of conversion rates of up to 100 ksp...
