Notes
- MCP3204 is a 4-channel ADC (CH0–CH3 only); pins 5 and 6 are No Connection.
- Pin numbers extracted directly from Table 3-1 "PIN FUNCTION TABLE" for MCP3204 SOIC package.
- DGND and AGND should both be connected to system ground; VREF should be decoupled with a capacitor.

- 2: See graphs that relate linearity performance to V REF levels.
3: Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity performance, particularly at elevated temperatures. See Section 6.2 'Maintaining Minimum Clock Speed' , 'Maintaining Minimum Clock Speed', for more information.
