The Microchip Technology Inc. MCP3204/3208
devices are successive approximation 12-bit Analogt o-Digital (A/D) Converters with on-board sample and
hold circuitry. The MCP3204 is programmable to provide two pseudo-differential input pairs or four singleended inputs. The MCP3208 is programmable to provide four pseudo-differential input pairs or eight singleended inputs. Differential Nonlinearity (DNL) is specified at ±1 LSB, while Integral Nonlinearity (INL) is
offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB
(MCP3204/3208-C) versions.
Communication with the devices is accomplished using a simple serial interface compatible with the SPI protocol. The devices are capable of conversion rates of up to 100 ksps. The MCP3204/3208 devices operate over
a broad voltage range (2.7V – 5.5V). Low current design permits operation with typical standby and active currents of only 500 nA and 320 µA, respectively.
