MAXIM Integrated Products, represented by Arrow Electronics , has introduced the MAX6677 single-wire, PWM-output temperature sensor, which operates down to a 1.8V power supply with 80 microamps (typ) current consumption.
Available in a tiny 6-pin SOT23 package, this sensor is suitable for industrial, HVAC, process control, and environmental monitoring applications.
The MAX6677 encodes temperature data in the PWM-output waveform, providing 1.5°C accuracy over a single wire, which easily interfaces with a microprocessor or microcontroller I/O port.
The device includes a push-pull output and has a 1.5kHz nominal output frequency.
Specified for the -55°C to +125°C temperature range, the MAX6677 operates with supply voltages from 1.8V to 5.5V.
