MAX6576/MAX6577 SOT Temperature Sensors with
Period/Frequency Output General Description The MAX6576/MAX6577 are low-cost, low-current temperature sensors with a single-wire output. The MAX6576
converts the ambient temperature into a square wave with
a period proportional to absolute temperature (°K). The
MAX6577 converts the ambient temperature into a square
wave with a frequency proportional to absolute temperature. The MAX6576 offers accuracy of ±3°C at +25°C,
±4.5°C at +85°C, and ±5°C at +125°C. The MAX6577
offers accuracy of ±3°C at +25°C, ±3.5°C at +85°C, and
±4.5°C at +125°C.
Both devices feature a single-wire output that minimizes
the number of pins necessary to interface with a microprocessor. The period/frequency range of the output square
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. Applications
