Using an External Referenc e
with AC Components
The MAX5122/MAX5123 have multiplying capabilities
within the reference input voltage range specifications.
Figure 13 shows a technique for applying a sinusoidal
input to REF, where the AC signal is offset before being
applied to the reference input.
Power-S upply and Bypassing
Considerations
On power-up, the input and DAC registers are cleared to
either zero (RSTVAL = DGND) or midscale (RSTVAL =
V
DD
). Bypass the power supply (V
DD
) with a 4.7μF
capacitor in parallel with a 0.1μF capacitor to AGND.
Minimize lead lengths to reduce lead inductance.
Layout Considerations
Digital and AC signals coupling to AGND can create
noise at the output. Connect AGND to the highest quali-
ty ground available. Use proper grounding techniques,
such as a multilayer board with a low-inductance
ground plane. Wire-wrapped boards and sockets are
not recommended. If noise becomes an issue, shield-
ing may be required.
