ISL70591SEH, ISL70592SEH, ISL73591SEH, ISL73592SEH
Radiation Hardened 100µA and 1mA Precision Current Sources
FN9335 Rev.0.00 Aug 30, 2018
The ISL70591SEH, ISL73591SEH, ISL70592SEH, and ISL73592SEH are radiation hardened precision 100µA and 1mA current source ICs. The devices have excellent accuracy of ±1% over a wide operating voltage range of 3V to 40V and over a temperature range of -55°C to +125°C. Fabricated with the Renesas proprietary PR40 Silicon On Insulator (SOI) process, the devices are immune to single event latch-up.
The high output impedance of the devices make them insensitive to the voltage drops across long lines. They can withstand a forward operating voltage...
