Analog Devices has introduced two digital temperature sensors with single-wire, pulse-width-modulation (PWM) outputs that offer the industry's most powerful combination of performance, low power consumption and small package size.
The output of the TMP05 and TMP06 is a square wave; its duty cycle is proportional to the absolute temperature. Both devices offer accuracy to +/-1 degrees C max from 0 degrees C to +70 degrees C, an operating temperature range from -55 degrees C to +150 degrees C, and a supply voltage range of +2.7 V to +5.5 V. They are available in space-saving 5-lead SC-70 and SOT-23 packages.
Both devices offer three modes of operation: daisy chain (allowing designers to connect any number of TMP05/06 sensors to the same microcontroller), continuously converting, and one-shot mode, which reduces the power consumption to 8.25 microW.
The TMP05 has a push-pull output (CMOS/TTL*), while the TMP06 has an open-drain output. Their combination of accuracy, low power and small package size make them ideal for battery and portable applications found in the industrial process control, consumer, instrumentation, and medical industries.
Pricing and Availability
Both the TMP05 and TMP06 are priced at $0.95 per unit in 1,000-piece quantities and are now available for sampling.
