Analog temperature sensors provide precision, networking
The Max31889 is for cold supply chain assets and the Max31825 reduces complexity of using multiple temperature sensors for consumer and factory automation.
The Max31889 delivers a precision of ±0.25-degree Celsius accuracy across a wide temperature range and measures cold-chain pharma product temperatures and comes in a 6-pin microDFN package.
The Max31825 allows up to 64 devices, all connected to the same parasitically powered 1-Wire bus, with the precision of ±1-degree Celsius accuracy. Each device has a unique code which can be optionally programmed with a location address, simplifying system design. The comes in a 6-bump WLP and has standby current of 2.5microamps.
The Max31889 is priced at $1.65 per unit in 1,000-up quantities. The Max31825 is priced at $1.55 in 1,000-up quantities. Both components have evaluation boards priced at $56.
