Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial clock input for data transfer with the ADC, with Schmitt-trigger input suited to opto-isolated interfaces; it may be continuous or non-continuous. |
| 2 | CLK | bidirectional | Clock pin that outputs the internal clock or, when the internal clock is disabled, accepts an external clock so multiple ADCs can run synchronized conversions. |
| 3 | CS | input | Active-low chip select that selects the ADC and acts as a frame sync; it can be hard-wired low for 3-wire operation via SCLK, DIN and DOUT. |
| 4 | IOUT1 | output | Output of the internal excitation current source, programmable to 10 uA, 210 uA or 1 mA, to which IEXC1 or IEXC2 can be switched. |
| 5 | AIN1+ | input | Positive input of analog channel 1. |
| 6 | AIN1- | input | Negative input of analog channel 1. |
| 7 | AIN2+ | input | Positive input of analog channel 2. |
| 8 | AIN2- | input | Negative input of analog channel 2. |
| 9 | REFIN+/AIN3+ | input | Positive reference input (typically 2.5 V across REFIN+ to REFIN-, usable from 0.1 V up to AVDD); also functions as positive input of analog channel 3. |
| 10 | REFIN-/AIN3- | input | Negative reference input, which may range from GND to AVDD-0.1 V; also functions as negative input of analog channel 3. |
| 11 | IOUT2 | output | Output of the internal excitation current source, programmable to 10 uA, 210 uA or 1 mA, to which IEXC1 or IEXC2 can be switched. |
| 12 | GND | power_in | Ground reference for the device. |
| 13 | AVDD | power_in | Analog supply voltage, 2.7 V to 5.25 V. |
| 14 | DVDD | power_in | Digital interface supply, 2.7 V to 5.25 V; it is independent of AVDD and sets the logic levels of the serial interface pins. |
| 15 | DOUT/RDY | output | Serial data output that also serves as data-ready flag, going low when a conversion completes and returning high after the data is read or before the next update; data is valid on the SCLK falling edge when CS is low. |
| 16 | DIN | input | Serial data input that feeds the ADC input shift register, which transfers data into the control register. |
