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. The sensor covers the full -40°C to 125°C range on both the sensing and operating temperature spec, making it suitable for industrial enclosures, automotive under-hood monitoring, and HVAC duct sensing where a simple frequency signal is easier to isolate or transmit over a twisted pair than an I²C bus. ## 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 Supply range is 2.7 V to 5.5 V. The SOT-23-6 footprint (SOT-6) is a standard small-outline transistor package. ## Lifecycle and sourcing reality The MAX6577ZUT+T carries an Active product status and is ROHS3 compliant. For a BOM line that needs a simple frequency-output temperature sensor, this part is a safe selection for new designs and production builds.","metaTitle":"MAX6577ZUT+T Temperature Sensor, Digital Output, 1Hz/°C","metaDescription":"MAX6577ZUT+T digital temperature sensor with 1Hz/°C frequency output, ±3°C accuracy, -40°C to 125°C range, 2.7V-5.5V supply.
