Description
Start condition.
Stop condition.
Acknowledge.
Package pin-programmable address bits.
Don’t care.
Write.
Read.
Second fuse link array for two-time programming. Logic 0 corresponds to first trim. Logic 1 corresponds to
second trim. Note that blowing Trim 2 before Trim 1 effectively disables Trim 1 and, in turn, allows only one-time
programming.
Shutdown connects wiper to Terminal B and open circuits Terminal A. It does not change the contents of the wiper register.
OTP programming bit. Logic 1 permanently programs the wiper.
Overwrite the fuse setting and program the digital potentiometer to a different setting. Note that upon power-up,
the digital potentiometer presets to either midscale or fuse setting, depending on whether the fuse link is blown.
Data bits.
OTP validation bits:
0, 0 = ready to program.
1, 0 = fatal error. Some fuses are not blown. Do not retry. Discard this unit.
1, 1 = programmed successfully. No further adjustments are possible.
