APPLICATIO S I FOR ATIO

Output Data Format

The LTC2414/LTC2418 serial output data stream is 32 bits

long. The first 3 bits represent status information indicat-

ing the sign and conversion state. The next 23 bits are the

conversion result, MSB first. The next 5 bits (Bit 5 to Bit 1)

indicate which channel the conversion just performed was

selected. The address bits programmed during this data

output phase select the input channel for the next conver-

sion cycle. These address bits are output during the sub-

sequent data read, as shown in Figure 3b. The last bit is a
