## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | AINA | input | Analog input for ADC A, a 1.0 V p-p input range centered at 2.5 V with 150 kΩ input resistance. |
| 2 | VREF | power_in | Internal 2.5 V voltage reference (typical) that should be bypassed with 0.1 µF to ground, or overdriven by an external reference of up to ±10% gain adjustment. |
| 3 | PWRDN | input | Power-down select; logic HIGH puts the device into power-down mode and drives the digital outputs to high impedance. |
| 4 | VD | power_in | Analog 5 V power supply for the ADCs. |

| 21 | D6B | output | ADC B digital output bit 6, offset binary coded. |
| 22 | D7B | output | ADC B digital output bit 7 (MSB), offset binary coded. |
| 23 | VDD | power_in | Digital output power supply, nominally 3 V to 5 V. |
| 24 | GND | power_in | Ground. |
| 25 | VD | power_in | Analog 5 V power supply for the ADCs. |
| 26 | ENCODE | input | Encode clock for ADCs A and B; both ADCs sample simultaneously on the rising edge, with up to 60 MSPS conversion rate. |
| 27 | GND | power_in | Ground. |
| 28 | AINB | input | Analog input for ADC B, a 1.0 V p-p input range centered at 2.5 V with 150 kΩ input resistance. |
