The MAX1003 is designed with separate analog and

digital power-supply and ground connections to isolate

high-current digital noise spikes from the more sensi-

tive analog circuitry. The high-current digital output

ground (OGND) and analog ground (GND) should be

at the same DC level, connected at only one location

on the board. This will provide best noise immunity and

imp rove d c onve rs ion a c c ura c y. Us e of s e p a ra te

ground planes is strongly recommended.

Signal-to-noise and distortion (SINAD) is the ratio of the

fundamental input frequency’s RMS amplitude to all

other ADC output signals. The output spectrum is limit-

ed to frequencies above DC and below one-half the

ADC sample rate.

The the ore tic a l minimum a na log -to-d ig ita l nois e is

caused by quantization error, and results directly from

the ADC’s resolution: SNR = (6.02N + 1.76)dB, where

N is the number of bits of resolution. Therefore, a per-

fect 6-bit ADC can do no better than 38dB.

MAX103

The entire board needs good DC bypassing for both

analog and digital supplies. Place the power-supply

bypass capacitors close to where the power is routed

onto the board, i.e., close to the connector. 10µF elec-

trolytic capacitors with low-ESR ratings are recom-

mended. For best effective bits performance, minimize

capacitive loading at the digital outputs. Keep the digi-

tal output traces as short as possible.

The FFT Plot (see Typical Operating Characteristics)

shows the result of sampling a pure 20MHz sinusoid at

a 90MHz clock rate. This FFT plot of the output shows

the output level in various spectral bands. The plot has

been averaged to reduce the quantization noise floor

and reveal the low-amplitude spurs. This emphasizes

the e xc e lle nt s p urious -fre e d yna mic ra ng e of the

MAX1003.

The MAX1003 requires a +5V ±5% power supply for

the analog supply (V ) and a +3.3V ±300mV power

The effective resolution (or effective number of bits) the

ADC provides can be measured by transposing the

e q ua tion tha t c onve rts re s olution to SINAD: N =

(SINAD - 1.76) / 6.02 (s e e Typ ic a l Op e ra ting
