... MCP3202 6.2 Maintaining Minimum Clock Speed When the MCP3202 initiates the sample period, charge is stored on the sample capacitor. When the sample period is complete, the device converts one bit for each clock that is received important for the user to note that a slow clock rate will allow charge to bleed off the sample cap while the conversion is taking place. At 85° ...
