Product details

16-bit sigma-delta ADC with integrated PGA and temperature sensor

It communicates over an SPI interface and operates from a single 2V to 5.5V supply on both the analog and digital sides.

860 SPS sampling rate — enough for slow sensor channels

At 860 samples per second, this ADC is suited for thermocouple, RTD, strain-gauge, and other low-bandwidth sensor inputs where the signal changes slowly. The integrated PGA lets you amplify small differential signals (down to microvolt levels) before conversion, saving an external instrumentation amplifier.

Single-supply flexibility from 2V to 5.5V

Both the analog and digital supply rails share the same 2V to 5.5V range, so a single 3.3V or 5V rail powers the entire ADC.

Frequently asked questions

What is the resolution of the ADS1118IDGSR?

It is a 16-bit sigma-delta ADC, providing 65536 code steps over the selected input range.

Does ADS1118IDGSR have an internal voltage reference?

Yes, the reference type is internal, so no external reference IC is needed.
