NOTES:
5. Although the ADC sampling clock latches the clamp pulse, it is not needed for basic clamp operation. However, depending on the
relationship between the sampling frequency and the clamp pulse frequency, a small abeat might be generated as V
SAG
. The latch circuit
is valid at this time.
6. Take care that the phase of ADIN input is inverted against the phase of the digital output, because the use of the built-in inverting amplifier
is standard. (Refer to “Digital Output”.)
