TDA9207

15/22

Register Sub-addressed - I

For Contrast & Drive adjustment, code 00 (dec) and 255 (dec) are not allowed.

For Output DC Level, code 00(dec), 01(dec), 02(dec) are not allowed (Register 06).

For Cut Off Output DC Level, output voltage is linear between code 10 and code 235 (Registers 0A, 0B, 0C).
