Ambient Temperature IC suggestions

Other Parts Discussed in Thread: TMP75B

Hey all,

I'm looking to make an ambient temperature sensor for an enclosure where temps can range between 25C to 125C. Looking mostly for a digital output sensor. Any suggestions would be great.

Thanks!

Is there an interface that you prefer such as I2C, SPI, UART, PWM? What kind of accuracy do you need? Do you need the smallest package or would you rather have one that is easier to solder?

Hello Ren,

I2C would be preferred , SPI could work as well. Size isn't a constrain, so it can be a SOT or QFN package for easy soldering. +/- 1C accuracy would suffice.

Thanks!
