Product details

Frequency-output temperature sensor in SOT-23-6

The Maxim Integrated MAX6577ZUT+T is a digital local temperature sensor that converts temperature directly to a frequency output at a scale of 1 Hz per °C. At 25°C the output sits at 25 Hz; at 125°C it reads 125 Hz. No ADC or serial interface is needed — a microcontroller timer channel or frequency counter is all it takes to read temperature.

Accuracy bands and what they mean for your measurement chain

Accuracy is ±3°C at 25°C and ±7.5°C over the full range.

Supply flexibility and package

The SOT-23-6 footprint (SOT-6) is a standard small-outline transistor package.

Frequently asked questions

What is the output frequency of MAX6577ZUT+T at 25°C?

At 25°C the output frequency is 25 Hz, following the 1 Hz per °C scale. At 0°C the output is 0 Hz; at 125°C it is 125 Hz. The frequency is proportional to the absolute temperature in degrees Celsius.

Is MAX6577ZUT+T RoHS compliant?

Yes, the MAX6577ZUT+T is ROHS3 compliant.

What is the accuracy of MAX6577ZUT+T?

Accuracy is rated at ±3°C (typical) and ±7.5°C over the full -40°C to 125°C temperature range. The tighter ±3°C spec applies at 25°C.

What are alternative parts to MAX6577ZUT+T?

Within the same Maxim family, the MAX6576 offers a 1 Hz/°K scale (Kelvin-based output) in the same SOT-23-6 footprint. The MAX6575 provides a period-modulated output instead of frequency. For a pin-compatible alternative with a different output format, check the MAX6575H/MAX6576H variants. No direct second-source from other manufacturers is listed; the MAX6577 is a Maxim-specific part.
