Hi,
three questions regarding REF60xx:
1) Does the yellow marked text refer to CFILT or to CL? (Can the ESR of CFILT really have a noteable impact on the stability as it isn’t a conventional OP/buffer)
2) What is the value of RFILT?
3) How is the noise density vs. CFILT? (also see figure 14. Output-Voltage Noise Spectrum)
Thanks
Fred
