MAX6576/MAX6577 SOT Temperature Sensors with Period/Frequency Output General Description Features
The MAX6576/MAX6577 are low-cost, low-current tem- ● Simple Single-Wire Output perature sensors with a single-wire output. The MAX6576 ● Two Output Types Available converts the ambient temperature into a square wave with • Temperature to Period (μs) (MAX6576) a period proportional to absolute temperature (°K). The • Temperature to Frequency (Hz) (MAX6577) MAX6577 converts the ambient temperature into a square wave with a frequency proportional to absolute tempera- ● ±0.8°C Accuracy at +25°C (±3°C max) ture. The MAX6576 offers accuracy of ±3°C at +25°C, ● No External Components ±4.5°C at +85°C, and ±5°C at +125°C. The MAX6577 ● Operates from +2.7V to +5.5V Supply Voltage offers accuracy of ±3°C at +25°C, ±3.5°C at +85°C, and ±4.5°C at +125°C. ● Low 140μA Typical Supply Current Both devices feature a single-wire output that minimizes ● Standard Operating Temperature Range: the number of pins necessary to interface with a micropro- -40°C to +125°C cessor. The period/frequency range of the output square ● Small 6-Pin SOT23 Package wave can be selected by hard-wiring the two time-select pins (TS0, TS1) to either VDD or GND. The MAX6576/ MAX6577 are available in space-saving 6-pin SOT23 packages.
