ISL71590SEH Highly Accurate Rad Hard Temperature Sensor

EDN Hot 100 Products for 2014 winner. Intersil’s ISL71590SEH is a radiation-hardened, low power, current output temperature sensor able to deliver a high level of accuracy over radiation exposure, time and temperature. The ISL71590SEH rad hard temperature sensor is ideal for remote temperature sensing in satellites and other space applications. Developers of the most advanced next generation satellite systems require temperature sensors that provide accuracy over the mission life of a satellite, eliminating the need for expensive radiation lot acceptance testing or spot shielding. With the ISL71590SEH’s ±1.7°C accuracy over temperature and at most -1°C change in accuracy over low dose rate radiation, the device is able to serve satellite temperature sensing functions that support most of a system’s telemetry data and calibration accuracy. The ISL71590SEH provides highly accurate, reliable temperature sensing and linearity over the full military temperature range of -55°C to +125°C, as well as over 50krad (Si) low dose rate and 300krad (Si) high dose rate irradiation. The ISL71590SEH won in the Analog category of the EDN Hot 100 Products for 2014 (http://www.edn.com/electronics-products/other/4437460/EDN-Hot-100-products-of-2014).
