Other Parts Discussed in Thread: OPA188, BUF634A, THS3491
Hi Team,
I want to design an electronic dc load. I drew a test board as in attachment. I have some concerns and questions about the design in schematic.
1. I plan to use INA293 (U1) as current sense amplifier. Is it suitable or should I use rail to rail zero drift amplifier like OPA188?
2. Which single supply amplifier do you advice for higher slew rates as a buffer (U3) for driving linear MOSFET (IXTX200N10L2) (Ciss=23nF)
3. If you have further comment, advice about the general topology and schematic I'll be glad to hear.
Best regards,
Ali
