Single-Supply 16-Bit ADC Driver
Figure 5 shows the LT6203 driving an LTC1864 unipolar
16-bit A/D converter. The bottom half of the LT6203 is in
a gain-of-one configuration and buffers the 0V negative
full-scale signal V
LOW
into the negative input of the
LTC1864. The top half of the LT6203 is in a gain-of-ten
configuration referenced to the buffered voltage V
LOW
and
drives the positive input of the LTC1864. The input range
of the LTC1864 is 0V to 5V, but for best results the input
range of V
IN
should be from V
LOW
(about 0.4V) to about
0.82V. Figure 6 shows an FFT obtained with a 10.1318kHz
coherent input waveform, from 8192 samples with no
windowing or averaging. Spurious free dynamic range is
seen to be about 100dB.
TYPICAL APPLICATIO S
Although the LTC1864 has a sample rate far below the gain
bandwidth of the LT6203, using this amplifier is not
necessarily a case of overkill. The designer is reminded
that A/D converters have sample apertures that are vanish-
ingly small (ideally, infinitesimally small) and make de-
mands on the upstream circuitry far in excess of what is
implied by the innocent-looking sample rate. In addition,
when an A/D converter takes a sample, it applies a small
capacitor to its inputs with a fair amount of glitch energy
and expects the voltage on the capacitor to settle to the
true value very quickly. Finally, the LTC1864 has a 20MHz
analog input bandwidth and can be used in undersampling
applications, again requiring a source bandwidth higher
than Nyquist.
