MAX6676 - Low-Voltage / 1.8kHz PWM Output Temperature Sensors

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 information contained in the duty cycle of the output square wave.

Features

MAX6676/MAX6677 EVALUATION KIT AVAILABLE 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 information 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 current is 80µA. All devices feature a single-wire output that minimizes the number of pins necessary to interface with a microprocessor (µP).
