Applications Information
Power-Supply and Bypassing
Considerations
Bypass the power supply with a 10μF capacitor in par-
allel with a 0.1μF capacitor to AGND. Minimize lead
lengths to reduce lead inductance. If noise becomes
an issue, use shielding and/or ferrite beads to increase
isolation.
Output Buffer
The MAX5200–MAX5203 include low-offset, low-noise
buffers enabling the output to source 15mA or sink
5mA. The output buffer operates at a slew rate of
0.6V/μs. With a 1/4 FS to 3/4 FS output transition, the
buffer output typically settles to 1 LSB in less than
25μs. The MAX5200–MAX5203 output buffers provide a
low 0.2
typical output impedance. The MAX5200–
MAX5203 buffer amplifiers typically produce
175nV/
Hz
noise at 10kHz.
