• Manufacturer Part Number: MAX1028
• Description: (MAX1030 / MAX1028 / MAX1026) 10-Bit 300ksps ADCs with FIFO / Temp Sensor / Internal Reference
• Manufacturer: Maxim Integrated Products

Total harmonic distortion (THD) is the ratio of the RMS
sum of the first five harmonics of the input signal to the
fundamental itself. This is expressed as:
where V1 is the fundamental amplitude, and V2–V5 are
the amplitudes of the first five harmonics.
Spurious-free dynamic range (SFDR) is the ratio of the
RMS amplitude of the fundamental (maximum signal
component) to the RMS value of the next-largest distor-
tion component.
