The MCP3301 13-bit A/D converter features full differential inputs and low power consumption in a small package that is ideal for battery-powered systems and remote data acquisition applications. 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 13- bit 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 ksps with tested specifications over a 4.5V to 5.5V supply range. The reference voltage can be varied from 400 mV to 5V, yielding input-referred resolution between 98 µV and 1.22 mV. The MCP3301 is available in 8-pin PDIP, 150 mil SOIC, and MSOP packages. The full differential inputs of this device enable a wide variety of signals to be used in applications such as remote data acquisition, portable instrumentation, and battery-operated applications.
