APPLICATIO S I FOR ATIO
below –FS, the conversion result is clamped to the value
corresponding to –FS – 1LSB.
Simultaneous Frequency Rejection
The LTC2436-1 internal oscillator provides better than
87dB normal mode rejection over the range of 49Hz to
61.2Hz as shown in Figure 4. For this simultaneous 50Hz/
60Hz rejection, F
When a fundamental rejection frequency different from
the range 49Hz to 61.2Hz is required or when the converter
must be sychronized with an outside source, the LTC2436-1
can operate with an external conversion clock. The conveter
