August 7, 2012 – Linear Technology Korea (CEO Hong Sa-kwak) announced the release of a high-precision temperature sensor (Product Name: LTC2996) suitable for 2.25V to 5.5V systems. The LTC2996 measures remote diode temperatures with an accuracy of ±1°C and die temperatures with an accuracy of ±2°C, while simultaneously eliminating errors caused by noise and series resistance. The device provides VPTAT (voltage-proportional-to-absolute-temperature) output, as well as alarm outputs for individual undertemperature and overheating defined by user-adjustable thresholds. No code is required for device configuration. The LTC2996 provides a quiescent current of 200µA and is a precise, space-saving micropower temperature monitoring solution.

With its accuracy, configurability, and code-free operation, the LTC2996 can be applied to a wide range of applications, including system thermal control, energy harvesting, desktop and laptop computers, network servers, and environmental monitoring. Users can choose to measure internal or remote temperatures, and the temperature threshold can be easily adjusted using a resistor divider. The temperature conversion is updated every 3.5ms to provide the system with sufficient time to respond to an alert. The device includes a 1.8V voltage reference output that can be shared with an external ADC or used to generate a temperature threshold voltage.

The LTC2996 is available in commercial, industrial, and automotive versions, supporting temperature ranges of 0°C to 70°C, -40°C to 85°C, and -40°C to 125°C, respectively, depending on the application. The LTC2996 is RoHS compliant and is available in a 10-pin 3mm x 3mm DFN package. Pricing starts at $1.95 per unit for quantities of 1,000.
