Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Active-low chip select that initiates conversions on the AD7323 and frames the serial data transfer. |
| 2 | DIN | input | Serial data input for the on-chip registers, clocked in on the falling edge of SCLK. |
| 3 | DGND | power_in | Digital ground reference for all digital circuitry; DGND and AGND must not be more than 0.3 V apart, even on a transient basis. |
| 4 | AGND | power_in | Analog ground reference for all analog circuitry, analog inputs and external reference; AGND and DGND must not be more than 0.3 V apart, even on a transient basis. |
| 5 | REFIN/OUT | bidirectional | Reference input/output providing the nominal 2.5 V internal reference (needs a 680 nF capacitor) or accepting an external reference, which is the default on power-up. |
| 6 | VSS | power_in | Negative supply voltage for the analog input section. |
| 7 | VIN0 | input | Analog input 0, multiplexed into the on-chip track-and-hold, with ±10 V, ±5 V, ±2.5 V or 0 V to +10 V ranges selectable via the range register. |
| 8 | VIN1 | input | Analog input 1, multiplexed into the on-chip track-and-hold, with ±10 V, ±5 V, ±2.5 V or 0 V to +10 V ranges selectable via the range register. |
| 9 | VIN2 | input | Analog input 2, multiplexed into the on-chip track-and-hold, with ±10 V, ±5 V, ±2.5 V or 0 V to +10 V ranges selectable via the range register. |
| 10 | VIN3 | input | Analog input 3, multiplexed into the on-chip track-and-hold, with ±10 V, ±5 V, ±2.5 V or 0 V to +10 V ranges selectable via the range register. |
| 11 | VDD | power_in | Positive supply voltage for the analog input section. |
| 12 | VCC | power_in | Analog supply voltage, 2.7 V to 5.25 V, for the ADC core, to be decoupled to AGND. |
| 13 | VDRIVE | power_in | Logic power supply input setting the interface voltage, decoupled to DGND, and not to exceed VCC by more than 0.3 V. |
| 14 | DOUT | output | Serial data output of the conversion result, MSB first, clocked out on the falling edge of SCLK, with 16 SCLKs required to access the data. |
| 15 | DGND | power_in | Digital ground reference for all digital circuitry; DGND and AGND must not be more than 0.3 V apart, even on a transient basis. |
| 16 | SCLK | input | Serial clock logic input used for accessing data from the AD7323 and as the clock source for the conversion process. |
