Low-Voltage, 1.8kHz PWM Output Temperature
Sensors
General Description
The MAX6676/MAX6677 are high-accuracy, low-power
temperature sensors with a single-wire output. The
MAX6676/MAX6677 convert the ambient temperature
into a ratiometric PWM output with temperature informa-
tion contained in the duty cycle of the output square
wave. The MAX6676 has an open-drain output and the
MAX6677 has a push-pull output.
The MAX6676/MAX6677 are specified for operation with
power-supply voltages from 1.8V to 3.6V, or from 3.6V to
5.5V (MAX6676 only). The typical unloaded supply cur-
rent is 80μA. All devices feature a single-wire output that
minimizes the number of pins necessary to interface
with a microprocessor (μP). The output is a square wave
Features

Ordering Information
with a nominal frequency of 1.8kHz (±20%) at +25°C.
The output format is decoded as follows:
Temperature (°C) = 398.15 ? (t 1 / t 2 ) - 273.15
Where t 1 is fixed with a typical value of 0.24ms and t 2 is
modulated by the temperature. The MAX6676/
MAX6677 operate from -40°C to +125°C and are avail-
