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
