What are the key features of XADS7028IRTER?
- 12-bit resolution with 8 analog input channels and 0.6 µs maximum conversion time for fast multichannel scanning
- 5.5 V maximum analog input voltage and low linearity error of 0.0488% ensure high measurement accuracy
- Compact WQFN-16 package minimizes board area in space-constrained industrial and medical data-acquisition designs
What is XADS7028IRTER used for?
The XADS7028IRTER is well suited for industrial process-control systems that need simultaneous monitoring of up to 8 sensor channels at 12-bit accuracy, such as temperature arrays, pressure transducers, and current-sense amplifiers feeding a central MCU. It is also used in medical monitoring equipment and building-automation panels where 5.5 V analog compatibility and fast 0.6 µs conversions allow real-time multi-channel sampling without external multiplexers.

Frequently Asked Questions
How many analog input channels does the XADS7028IRTER support, and what resolution does it provide?
The XADS7028IRTER integrates 8 analog input channels with 12-bit resolution, yielding 4096 discrete output codes per channel. This combination eliminates the need for an external multiplexer in most multi-sensor applications, reducing BOM cost and board space in industrial data-acquisition designs that monitor several signals simultaneously.
How fast can the XADS7028IRTER convert a single analog sample, and why does it matter for real-time systems?
The maximum conversion time is 0.6 µs per sample, allowing throughput rates sufficient for scanning all 8 channels many times per millisecond. In motor-drive current-sensing or fast PID control loops operating at switching frequencies above 100 kHz, this sub-microsecond conversion speed ensures the processor receives fresh analog data before the next control cycle begins.
What is the maximum analog input voltage the XADS7028IRTER can accept, and how does this affect sensor selection?
The absolute maximum analog input voltage is 5.5 V, covering standard 5 V sensor output ranges without signal attenuation. Designers can directly connect 0–5 V output pressure transducers, 4–20 mA current-loop receivers with a 250 Ω shunt (giving 0–5 V), or ratiometric bridge sensors powered from a 5 V rail without adding a level-shift stage.
How does the WQFN-16 package influence thermal and layout considerations for the XADS7028IRTER?
The WQFN-16 package measures approximately 3 mm × 3 mm with an exposed thermal pad, keeping the PCB footprint small while enabling heat dissipation into the copper pour. At typical ADC power levels below 5 mW, self-heating is negligible; the main layout concern is keeping analog input traces short and separated from digital clock lines to achieve the rated 0.0488% linearity error.
