The MCP3204 device is successive approximation 12-bit Analogto-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. Differential non-linearity (DNL) is specified at ±1 LSB, while Integral non-linearity (INL) is offered in ±1 LSB (MCP3204).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 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. The MCP3204 is offered in 14-pin PDIP, 150 mil SOIC and TSSOP packages.
