Frequently Asked Questions
What supply voltage range does the TMP1075NDRLR support, and how does this benefit battery-powered designs?
The TMP1075NDRLR operates from 1.7 V to 3.6 V, making it compatible with single-cell LiPo batteries and 3.3 V power rails commonly used in IoT and wearable designs. Its 8 µA typical supply current further extends battery life in energy-constrained applications.
How many TMP1075NDRLR sensors can share a single I2C bus, and what limits that count?
Up to 4 TMP1075NDRLR devices can share the same I2C/SMBus bus because the device supports 4 selectable 7-bit addresses via the A0–A1 pins. Each sensor reports 12-bit temperature data at up to 27 conversions per second.
When would TMP1075NDRLR be preferred over a simpler 8-bit sensor for an industrial temperature-monitoring system?
The TMP1075NDRLR provides 12-bit resolution with ±1°C accuracy across the full -40°C to +125°C industrial temperature range, enabling finer threshold control and more reliable alert detection compared to 8-bit sensors, which typically offer only 0.5°C resolution.
