Figure 11 shows the MAX6066 precision bandgap ref-
erence used as a common reference for multiple con-
verters. The 2.500V output of the MAX6066 is followed
by a 10Hz lowpass filter and precision voltage-divider.
The MAX4254 buffers the taps of this divider to provide
the 1.75V, 1.5V, and 1.25V sources to drive REFP,
REFN, and COM. The MAX4254 provides a low offset
voltage and low noise level. The individual voltage fol-
lowers are connected to 10Hz lowpass filters, which fil-
ter both the reference-voltage and amplifier noise to a
level of 3nV/
√Hz. The 1.75V and 1.25V reference volt-
ages set the differential full-scale range of the associat-
ed ADCs at ±0.5V.
The common power supply for all active components
removes any concern regarding power-supply
sequencing when powering up or down.
With the outputs of the MAX4252 matching better than
0.1%, the buffers and subsequent lowpass filters sup-
port as many as 160 MAX1193 ADCs.
