The Microchip Technology Inc. MCP3202 is a successive approximation 12-bit Analog-to-Digital (A/D) Converter with on-board sample and hold circuitry. 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. 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 100ksps at 5V and 50ksps at 2.7V. The MCP3202 device operates over a broad voltage range (2.7V 5.5V). Low current design permits operation with typical standby and active currents of only 500nA and 375A, respectively. The MCP3202 is offered in 8-pin PDIP, TSSOP and 150mil SOIC packages.
