Applications Information
Power-On Reset
When power is first applied, internal power-on reset cir-
cuitry activates the MAX1061/MAX1063 in external
clock mode and sets INT high. After the power supplies
stabilize, the internal reset time is 10s, and no conver-
sions should be attempted during this phase. When
using the internal reference, 500s are required for
VREF to stabilize.
Internal and External Reference
The MAX1061/MAX1063 can be used with an internal
or external reference voltage. An external reference
can be connected directly to REF or REFADJ.
An internal buffer is designed to provide +2.5V at REF for
both the MAX1061 and the MAX1063. The internally
trimmed +1.22V reference is buffered with a +2.05V/V
gain.
Internal Reference
With the internal reference, the full-scale range is +2.5V
with unipolar inputs and ±1.25V with bipolar inputs. The
internal reference buffer allows for small adjustments
(±100mV) in the reference voltage (Figure 7).
Note: The reference buffer must be compensated with
an external capacitor (4.7F min) connected between
REF and GND to reduce reference noise and switching
spikes from the ADC. To further minimize noise on the
reference, connect a 0.01F capacitor between
REFADJ and GND.
External Reference
With both the MAX1061 and MAX1063, an external ref-
erence can be placed at either the input (REFADJ) or
the output (REF) of the internal reference buffer amplifier.
Using the REFADJ input makes buffering the external
reference unnecessary. The REFADJ input impedance
is typically 17k.
