The MAX6576/MAX6577 are low-cost, low-current tem-

perature 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.

♦ Simple Single-Wire Output

♦ Two Output Types Available

Temperature to Period (µs) (MAX6576)

Temperature to Frequency (Hz) (MAX6577)

♦ ±0.8°C Accuracy at +25°C (±3°C max)

♦ No External Components

♦ Operates from +2.7V to +5.5V Supply Voltage

♦ Low 140µA Typical Supply Current

Both devices feature a single-wire output that minimizes

the number of pins necessary to interface with a micro-

processor. The period/frequency range of the output

square wave can be selected by hard-wiring the two

♦ Standard Operating Temperature Range:

-40°C to +125°C

♦ Small 6-Pin SOT23 Package

time-select pins (TS0, TS1) to either V

or GND. The

MAX6576/MAX6577 are available in space-saving 6-pin

SOT23 packages.
