240 SPS sampling with 16-bit resolution
The ADS1110A3IDBVRG4: The converter delivers 16-bit resolution at 240 samples per second — fast enough for slow-moving process signals, temperature, pressure, or strain-gauge outputs, but not for audio or vibration above a few hundred Hz. The sigma-delta architecture gives good in-band noise shaping, and the internal reference removes the need for an external voltage source, saving board space in the SOT-23-6 footprint.
The SOT-23-6 package limits total power dissipation, so confirm the thermal budget if the ADC runs continuously near the top of the temperature range at the full 5.5 V supply.
Date-code and marking consistency should be verified on receipt — the SOT-23-6 laser etch is small and easily counterfeited, so a decap or X-ray inspection is warranted for high-reliability BOM lines.
I²C interface with selectable address
The selectable address feature lets you put up to eight of these ADCs on the same I²C bus, each with a unique slave address, by hard-wiring the address pin — useful for multi-channel data acquisition without a multiplexer.
