DATASHEET ISL71590SEH, ISL73590SEH Radiation Hardened, 2-Terminal Temperature Transducer FN8376 Rev.3.00 Sep 14, 2018 The ISL71590SEH and ISL73590SEH are temperature-to-current transducers possessing two terminals. They have a high impedance current output that allows them to be insensitive to voltage drops across long lines. When provided a differential voltage between 4V and 33V, the devices act as constant current regulators that generate a current equal to 1µA/Kelvin (K). These devices are specified across the -55°C to +125°C temperature range and with ±1.7°C accuracy without the need of additional circuitry, and also capable of operating up to +150°C. With power requirements as low as 1.
