INA250 is a family of current shunt monitor with integrated shunt. The INA250EVM (INA250AxEVM) is intended to provide basic functional evaluation of INA250A1, INA250A2, INA250A3 and INA250A4 devices in the family. The fixture layout is not intended to be a model for the target circuit, nor is it (...)
- INA250EVM consists of one PCB with an option to cut out four individual PCBs one for each of the four devices (INA250A1, INA250A2, INA250A3 and INA250A4).
- Ease of access to all device pins.
- Banana jack terminals on IN+ and IN- pins for ease of connection.

SPICE-based analog simulation program
— TINA-TI provides all the conventional DC, transient and frequency domain analysis of SPICE and much more. TINA has extensive post-processing capability that allows you to format results the way you want them. Virtual instruments allow you to select input waveforms and probe circuit nodes voltages (...)
30A Range Bidirectional Current Shunt Monitor Reference Design
— This verified design can accurately measure current across a range of 30 A on a bus that carries up to 36-V common mode voltage over a range of -40°C to +85°C. This design can measure current from 0 A to 30 A with a grounded reference or -30 A to 0 A with a 16-V reference. The (...)
Current Shunt Monitor with Transient Robustness Reference Design
— This high-side current shunt monitor is used to measure the voltage developed across a current-sensing resistor when current passes through it.
Additionally, an external protection circuit is implemented to provide surge and fast-transient protection and demonstrate the different immunity levels to (...)
