MCP3202  
2.7V Dual Channel 12-Bit A/D Converter  
with SPI Serial Interface  
Features  
Description  
• 12-bit resolution  
The MCP3202 is a successive approximation 12-bit  
analog-to-digital (A/D) converter with on-board sample  
and hold circuitry.  
• ±1 LSB maximum DNL  
• ±1 LSB maximum INL (MCP3202-B)  
• ±2 LSB maximum INL (MCP3202-C)  
The MCP3202 is programmable to provide a single  
pseudo-differential input pair or dual single-ended  
inputs. Differential Nonlinearity (DNL) is specified at  
±1 LSB, and Integral Nonlinearity (INL) is offered in  
±1 LSB (MCP3202-B) and ±2 LSB (MCP3202-C)  
versions.  
• Analog inputs programmable as single-ended or  
pseudo-differential pairs  
• On-chip sample and hold  
• SPI Serial Interface (Modes 0,0 and 1,1)  
• Single supply operation: 2.7V-5.5V  
Communication with the device is done using a simple  
serial interface compatible with the SPI protocol. The  
device is capable of conversion rates of up to 100 ksps  
at 5V and 50 ksps at 2.7V.  
• 100 ksps maximum sampling rate at VDD = 5V  
• 50 ksps maximum sampling rate at VDD = 2.7V  
• Low power CMOS technology  
• 500 nA typical standby current, 5 µA maximum  
• 550 µA maximum active current at 5V  
• Industrial temp range: -40°C to +85°C  
• 8-pin MSOP, PDIP, SOIC and TSSOP packages  
The MCP3202 operates over a broad voltage range,  
2.7V to 5.5V. Low-current design permits operation with  
typical standby and active currents of only 500 nA and  
375 µA, respectively.  
The MCP3202 is offered in 8-pin MSOP, PDIP, TSSOP  
and 150 mil SOIC packages.
