Reference Buffer
The MAX11044/MAX11044B/MAX11045/MAX11045B/
MAX11046/MAX11046B and MAX11054/MAX11055/
MAX11056 have a built-in reference buffer to provide a
low-impedance reference source to the SAR convert-
ers. This buffer is used in both internal and external ref-
erence mode. The reference buffer output feeds five
RDC pins. The RDC pins should be all connected
together on the PCB. The reference buffer is externally
compensated and requires at least 10μF on the RDC
node. For best performance, provide a total of at least
80μF on the RDC outputs.
Transfer Functions
Figures 8 and 9 show the transfer functions for all the
formats and devices. Code transitions occur halfway
between successive-integer LSB values.
