Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AIN0 | input | Single-ended analog input channel 0 to the 16-channel multiplexer and track/hold. |
| 2 | AIN1 | input | Single-ended analog input channel 1 to the 16-channel multiplexer and track/hold. |
| 3 | AIN2 | input | Single-ended analog input channel 2 to the 16-channel multiplexer and track/hold. |
| 4 | AIN3 | input | Single-ended analog input channel 3 to the 16-channel multiplexer and track/hold. |
| 5 | AIN4 | input | Single-ended analog input channel 4 to the 16-channel multiplexer and track/hold. |
| 6 | AIN5 | input | Single-ended analog input channel 5 to the 16-channel multiplexer and track/hold. |
| 7 | AIN6 | input | Single-ended analog input channel 6 to the 16-channel multiplexer and track/hold. |
| 8 | AIN7 | input | Single-ended analog input channel 7 to the 16-channel multiplexer and track/hold. |
| 9 | AIN8 | input | Single-ended analog input channel 8 to the 16-channel multiplexer and track/hold. |
| 10 | AIN9 | input | Single-ended analog input channel 9 to the 16-channel multiplexer and track/hold. |
| 11 | AIN10 | input | Single-ended analog input channel 10 to the 16-channel multiplexer and track/hold. |
| 12 | AIN11 | input | Single-ended analog input channel 11 to the 16-channel multiplexer and track/hold. |
| 13 | AIN12 | input | Single-ended analog input channel 12 to the 16-channel multiplexer and track/hold. |
| 14 | AIN13 | input | Single-ended analog input channel 13 to the 16-channel multiplexer and track/hold. |
| 15 | AIN14 | input | Single-ended analog input channel 14 to the 16-channel multiplexer and track/hold. |
| 16 | CNVST/AIN15 | input | Active-low conversion start input (programmed via the setup register, see Table 3) that also serves as analog input channel 15. |
| 17 | REF | input | Reference input; bypass to GND with a 0.1µF capacitor. External reference range is 1V to VDD. |
| 18 | GND | power_in | Ground. |
| 19 | VDD | power_in | Power input; bypass to GND with a 0.1µF capacitor. Supply is 4.75V to 5.25V for the MAX11624EEG+T (ordering table). |
| 20 | CS | input | Active-low chip-select input; when CS is low the serial interface is enabled, and when CS is high DOUT is high impedance. |
| 21 | SCLK | input | Serial clock input that clocks data in and out of the serial interface; duty cycle must be 40% to 60%. |
| 22 | DIN | input | Serial data input latched into the serial interface on the rising edge of SCLK. |
| 23 | DOUT | tri_state | Serial data output clocked out on the falling edge of SCLK; high impedance when CS is connected to VDD. |
| 24 | EOC | output | End-of-conversion output; data is valid after EOC pulls low. |
