Overview
Description
The ISL70592SEHEVAL1Z evaluation board provides a quick and easy method to evaluate the ISL70592SEH radiation hardened 1mA precision constant current source designed for thermistor and other resistive sensor excitation applications. The ISL70592SEH's two-terminal floating type topology allows the load to be connected at the high side (+V pin), low side (-V pin), or both the high and low sides of the current source. It is specifically designed to operate in the harsh environment of space.
A thorough knowledge of the ISL70592SEH's operation is required to use this evaluation board properly. Refer to the ISL70592SEH datasheet for information about the device's function and performance.
Features
- Convenient test points and connections for test equipment
- Jumpers to select between a short (0Ω resistor), 100Ω resistor or 1kΩ resistor at either the input side or output side, or at both sides of the current source
- Banana jacks for:
- Power
- Ground
- Connecting external loads and circuitry such as external sensors and signal conditioning circuits (for example, instrumentation amplifiers) between VS and VP and/or between VM and GND
