DESCRIPTION  
VREF  
The Microchip Technology Inc. MCP3204/3208  
devices are successive approximation 12-bit Ana-  
log-to-Digital (A/D) Converters with on-board sample  
and hold circuitry. The MCP3204 is programmable to  
provide two pseudo-differential input pairs or four sin-  
gle-ended inputs. The MCP3208 is programmable to  
provide four pseudo-differential input pairs or eight sin-  
gle-ended inputs. Differential Nonlinearity (DNL) is  
specified at ±1 LSB, and Integral Nonlinearity (INL) is  
offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB  
(MCP3204/3208-C) versions. Communication with the  
devices is done using a simple serial interface compat-  
ible with the SPI protocol. The devices are capable of  
conversion rates of up to 100ksps. The MCP3204/3208  
devices operate over a broad voltage range (2.7V -  
5.5V). Low current design permits operation with typi-  
cal standby and active currents of only 500nA and  
320µA, respectively. The MCP3204 is offered in 14-pin  
PDIP, 150mil SOIC and TSSOP packages, and the  
MCP3208 is offered in 16-pin PDIP and SOIC pack-  
ages.
