Microchip Tech · Analog To Digital Converters (ADC) · SOIC-16
MCP3208-CI from Microchip Tech, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CH0 | input | Analog input for multiplexed channel 0; each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 2 | CH1 | input | Analog input for multiplexed channel 1; each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 3 | CH2 | input | Analog input for multiplexed channel 2; each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 4 | CH3 | input | Analog input for multiplexed channel 3; each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 5 | CH4 | input | Analog input for multiplexed channel 4 (MCP3208 only); each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 6 | CH5 | input | Analog input for multiplexed channel 5 (MCP3208 only); each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 7 | CH6 | input | Analog input for multiplexed channel 6 (MCP3208 only); each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 8 | CH7 | input | Analog input for multiplexed channel 7 (MCP3208 only); each channel pair can be programmed as two single-ended channels or as one pseudo-differential input. |
| 9 | DGND | power_in | Digital ground connection to the internal digital circuitry; if no ground plane is used it must be connected to VSS on the board, and with a ground plane it should be tied to the analog ground plane. |
| 10 | CS/SHDN | input | Pulling low initiates communication with the device, and pulling high ends a conversion and places the device in low-power standby; it must be pulled high between conversions. |
| 11 | DIN | input | SPI serial data input used to load channel configuration data into the device. |
| 12 | DOUT | output | SPI serial data output used to shift out the A/D conversion results; data always changes on the falling edge of each clock. |
| 13 | CLK | input | SPI serial clock that initiates a conversion and clocks out each bit of the conversion; clock speed constraints are given in Section 6.2. |
| 14 | AGND | power_in | Analog ground connection to the internal analog circuitry; connect to the analog ground plane when one is available. |
| 15 | VREF | power_in | Reference voltage input for the A/D converter. |
| 16 | VDD | power_in | Power supply input, +2.7V to 5.5V. |
