MCP3301  
13-Bit Differential Input, Low Power A/D Converter  
with SPI™ Serial Interface  
Features  
General Description  
• Full Differential Inputs  
The Microchip Technology Inc. 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.  
• ±1 LSB max DNL  
• ±1 LSB max INL (MCP3301-B)  
• ±2 LSB max INL (MCP3301-C)  
• Single supply operation: 2.7V to 5.5V  
• 100 ksps sampling rate with 5V supply voltage  
• 50 ksps sampling rate with 2.7V supply voltage  
• 50 nA typical standby current, 1 µA max  
• 450 µA max active current at 5V  
• Industrial temp range: -40°C to +85 °C  
• 8-pin MSOP, PDIP and SOIC packages  
• MXDEV™ Evaluation kit available  
Incorporating a successive approximation architecture  
with on-board sample and hold circuitry, this 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 per-  
mits operation with typical standby and active currents  
of only 50 nA and 300 µA, respectively. The device  
operates over a broad voltage range of 2.7V to 5.5V  
and is capable of conversion rates of up to 100 ksps.  
The reference voltage can be varied from 400 mV to  
5V, yielding input-referred resolution between 98 µV  
and 1.22 mV.  
Applications  
• Remote Sensors  
• Battery Operated Systems  
• Transducer Interface  
Package Types  
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.
