The peak data register is a 16-bit read only register. Set
the PEAK bit to 1 to enable the PEAK function. This reg-
ister stores the peak value of the ADC conversion
result. First, the current ADC result is saved to the
PEAK register, then the new ADC conversion result is
compared to this value. If the new value is larger than
the value in the peak register, the MAX1497/MAX1499
save the new value to the peak register. If the new
value is less than the value in the peak register, the
value in the peak register remains unchanged. Set the
PEAK bit to zero to clear the value in the PEAK register.
The data is represented in two’s complement format.
For the MAX1499, the data is 16-bit and D15 is the MSB.
For the MAX1497, the data is 12-bit, D15 is the MSB,
and D4 is the LSB followed by 4 trailing sub-bits.
