Description
Start condition.
Stop condition.
Acknowledge.
Package pin-programmable address bits.
Don’t care.
Write.
Read.
RDAC subaddress select bit.
Shutdown connects wiper to B terminal and open circuits the A terminal. It does not change the
contents of the wiper register.
OTP programming bit. Logic 1 programs the wiper permanently.
Overwrites the fuse setting and programs the digital potentiometer to a different setting. Upon
power-up, the digital potentiometer is preset to either midscale or fuse setting, depending on
whether the fuse link was blown.
