8.9 OTP Programming

Figure 18. OTP Programming Connection

For programming of the OTP, an additional voltage has to be applied to the pin PROG. It has to be buffered by a fast 100nF capacitor (ceramic)

and a 10µF capacitor. The information to be programmed is set by command 25. The OTP bits 16 until 45 are used for AMS factory trimming and

cannot be overwritten.

Remark: For normal operation, after programming, apply 100k pull up resistor at PROG pin!
