The DS1621S+ has an accuracy of ±0.5°C from -10°C to +85°C and ±1°C from -40°C to +125°C.
The DS1621S+ uses a 3-wire interface, which is similar to SPI, but not exactly the same. It's a proprietary interface developed by Maxim.
Yes, the DS1621S+ has built-in noise filtering and is designed to operate in noisy environments. However, it's still recommended to follow proper PCB design and layout practices to minimize noise.
The DS1621S+ has a conversion time of 100ms, so you can read the temperature at a maximum rate of 10 times per second.
Yes, the DS1621S+ is designed for high-reliability applications and is qualified for automotive and industrial uses. It's also available in a Pb-free and RoHS-compliant package.
