LMH6401: LMH6401 register 04h & 05h calibration

Part Number: LMH6401

Hi Team,

Do you have mathematic formulas of Thermal Feedback Gain Control (address = 4h) and Thermal Feedback Frequency Control (address = 5h)? Or calibration method?

thanks a lot.

Hello Yang,

The thermal feedback gain and frequency control is analog based internal to the closed feedback loop structure of the amplifier. With thermal feedback off, temperature variation shown in Figure 61 shows a gain variation of about 1.7%. With this temperature control structure internal to this device, the gain variation decreases to about 0.35%. We are unable to disclose the specifics of this reduction of overshoot.

Thank you,
Sima
