HDC2080 Humidity and Temperature Sensor

Specifications

Product Overview

The HDC2080 is a Texas Instruments humidity and temperature sensor for systems requiring relative humidity and temperature measurement in a compact package. It is supplied in a WSON (DMB), 6-pin package with a 3.00 mm × 3.00 mm body, and its relative humidity sensor covers 0% to 100% RH under non-condensing conditions.

Recommended VDD operation is 1.62 V to 3.6 V. The humidity accuracy is ±2% RH typical and ±3% RH maximum over 0°C < TA < 60°C under non-condensing conditions, while factory-calibrated temperature accuracy is ±0.2°C typical and ±0.4°C maximum. The temperature sensor recommended operating free-air range is -40°C to 125°C, while the relative humidity sensor recommended free-air range is -20°C to 70°C.

The interface is I2C, using SDA and SCL open-drain lines that require pullup resistors to VDD. The ADDR pin selects address 1000000 when unconnected or tied to GND, or 1000001 when tied to VDD. A push-pull DRDY/INT pin provides data-ready or interrupt output, and an integrated heater is specified with 90 mA typical current at VDD = 3.3 V.

Procurement Notes

When requesting a quote for HDC2080, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For memory and storage sourcing, density, organization, speed grade, voltage, package, temperature grade, date code, lifecycle status and original packing condition should be verified before approval.
