The 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 non-linearity (DNL) is specified at ±1 LSB, and Integral non-linearity (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 100 ksps at 5V and 50 ksps at 2.7V.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.
