Analog To Digital Converters (ADC) FAQ

What is the function of the internal voltage reference?

The ADS1110A2IDBVT includes an onboard 2.048V reference, which provides a stable input range of ±2.048V for differential measurements without requiring external reference components.

How does the device manage power consumption during idle periods?

In single-conversion mode, the ADS1110 automatically powers down after completing a conversion cycle, significantly reducing current draw while waiting for the next measurement trigger.

What is the purpose of the programmable gain amplifier (PGA)?

The PGA amplifies small input signals by factors up to 8, enabling the ADC to resolve fine voltage changes and maintain high resolution even when measuring low-level sensor outputs.
