... DCP will always commence at mid-scale (64 tap position). The low voltage, low power consumption, and small package of the ISL23348 make it an ideal choice for use in battery operated equipment. In addition, the ISL23348 has a V pin allowing down to 1.2V bus operation, independent from the V value ...

... I I The high (RHi and low (RLi terminals of the ISL23348 are equivalent to the fixed terminals of a mechanical potentiometer. RHi and RLi are referenced to the relative position of the wiper and not the voltage potential on the terminals. With WRi set to 127 decimal, the wiper will be closest to RHi, and with the WRi set to 0, the wiper is closest to RLi ...

... Identification byte with the R/W bit set to “0”, an Address Byte, a second START, and a second Identification byte with the R/W bit set to “1”. After each of the three bytes, the ISL23348 responds with an ACK; then the ISL23348 transmits Data Byte. The master terminates the read operation issuing a NACK (ACK) and a STOP condition following the last bit of the last Data Byte (see Figure 30) ...
