Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF+ | input | Positive reference voltage input, which must be held within 2.5V≤REF+≤Vcc+0.1. |
| 2 | ANALOGIN | input | Analog signal input that the on-chip sample-and-hold samples for conversion. |
| 3 | REF- | input | Negative reference voltage input, which must be held within -0.1V≤REF-≤2.5V. |
| 4 | GND | power_in | Ground. |
| 5 | CS | input | Chip select input; CS is driven low to start a conversion sequence and must be high (or I/OCLOCK held low for 36 internal clock cycles) to complete it. |
| 6 | DATAOUT | output | Data conversion interface output that carries the serial conversion result, MSB (D7) first. |
| 7 | I/OCLOCK | input | External I/O clock input that shifts the conversion result out and controls the conversion timing; its high and low pulse widths must be at least 190 ns. |
| 8 | VCC | power_in | Supply voltage; the electrical characteristics table gives 3 V to 5.5 V (the features list states 3 V to 6.5 V). |
