Product Overview
ADS1110A0IDBVR is a single differential-input, low-power 16-bit delta-sigma ADC that integrates the reference, oscillator and PGA in a six-pin package. It targets low-bandwidth sensor and transmitter applications that need an absolute conversion scale without an external reference IC.
The key distinction from ADS1100 is the onboard 2.048 V reference. The full-scale differential range is set by that reference and the PGA, so supply variation does not directly redefine the transfer scale as it does in a supply-ratiometric converter.
Data rate and resolution remain linked: 240 SPS is the fastest setting, while 15 SPS provides the full 16-bit output mode. The exact A0/DBVR code fixes both I²C-address option and 3000-piece reel packaging.

Functional Highlights
Integrated reference reduces absolute-measurement BOM
A known 2.048 V reference simplifies voltage, current-shunt and temperature-sensor scaling where the result must not move with VDD.
PGA and data-rate settings jointly set usable signal range and noise
Higher gain increases sensitivity to small differential signals, while slower conversion provides more output resolution and filtering.
Design Considerations
- Keep both analog inputs inside the allowed common-mode range even when the differential signal is small.
- Choose PGA headroom for sensor offset and fault overrange, not only nominal span.
- Reserve the A0 fixed I²C address before adding multiple ADS1110 address variants.
