Q16. What are the General Purpose Input voltage threshold for AD4114, AD4115?
| Specification/ Product | AVDD - AVSS | Input High Voltage (Min) |
Input Low Voltage (Max) |
|
| AD4114 | 3.0V to 3.6V | AVSS + 2V | AVSS + 0.45V | |
| 4.5V to 5.5V | AVSS + 3V | AVSS + 0.7V | ||
| AD4115 | 4.5V to 5.5V | AVSS + 3V | AVSS + 0.7V | |
Note that although allowed by the specification, there could be an increase in the device supply current when an input-high-level of 3V is used for the GPIO when AVDD = 5V. The supply current specifications are only valid when the voltages of any enabled/active “digital” input is at its supply or ground voltage.
