onto the analog lines. If the analog and digital sections
share the same supply, isolate the digital and analog
supply by connecting them with a low value (10
)
resistor or ferrite bead.
The ADC is sensitive to high-frequency noise on the
AVDD supply. Bypass AVDD to AGND with a 0.1F
capacitor in parallel with a 1F to 10F low-ESR capaci-
tor with the smallest capacitor closest to the device.
Keep capacitor leads short to minimize stray inductance
Definitions
Integral Nonlinearity
Integral nonlinearity (INL) is the deviation of the values
on an actual transfer function from a straight line. This
straight line can be either a best-straight-line fit or a line
drawn between the end points of the transfer function,
once offset and gain errors have been nullified. The
static linearity parameters for the MAX1157/MAX1159/
MAX1175 are measured using the endpoint method.
Differential Nonlinearity
Differential nonlinearity (DNL) is the difference between
an actual step-width and the ideal value of 1LSB. A
DNL error specification of 1LSB guarantees no missing
codes and a monotonic transfer function.
Signal-to-Noise Ratio
For a waveform perfectly reconstructed from digital
samples, signal-to-noise ratio (SNR) is the ratio of the
full-scale analog input (RMS value) to the RMS quanti-
zation error (residual error). The ideal, theoretical mini-
mum analog-to-digital noise is caused by quantization
noise error only and results directly from the ADC’s res-
olution (N bits):
SNR = ((6.02 N) + 1.76)dB
where N = 14 bits.
