FAQs

Q: What is the difference between single-ended and differential inputs?
A: Single-ended inputs measure voltage relative to ground, while differential inputs measure between two pins. This ADC supports eight single-ended channels, simplifying designs where signals reference a common ground.

Q: Can I use this ADC with 3.3V microcontrollers?
A: Yes. Its 2.7V–5.25V digital supply range ensures full SPI compatibility with 3.3V or 5V logic systems without level shifters.

Q: Is an external reference voltage required?
A: No. It uses supply-referenced conversion, eliminating the need for an external reference IC in basic applications.

Q: What is the typical power consumption at 200kSPS?
A: Approximately 1.8mW at 3.6V and 200kSPS (see datasheet Section 6.5 for detailed specifications).
