TIHDC2080DMBR
Overview
The HDC2080DMBR is a digital humidity and temperature sensor featuring an integrated 14-bit ADC and I2C interface. It is designed for ultra-low power operation, consuming only 550 nA during a typical measurement cycle, making it ideal for battery-powered IoT applications. The sensor is housed in a compact 3mm x 3mm WSON package and supports a wide supply voltage range from 1.62V to 3.6V.
Why Choose This Part
This sensor offers excellent power efficiency with a sleep current of 50 nA and an integrated auto-measurement mode that allows the device to wake up, sample, and return to sleep without MCU intervention. It features high accuracy of +/-2% RH and a fast response time of 8 seconds, while the 1.62V minimum VDD allows for operation directly from a variety of battery chemistries.
Applications
Key Specifications
Getting Started
To evaluate the sensor, use the HDC2080EVM evaluation module which connects to a PC via USB. Developers can interface with the device over I2C using standard 7-bit addressing and should reference TI's humidity sensor software library for rapid driver integration.
