_______________Detailed Description

The MAX1172 requires few external components to

achieve the stated operation and performance. Figure

2 shows the typical interface requirements when using

the MAX1172 in normal circuit operation. The following

section provides a description of the pin functions and

outlines critical performance criteria for achieving the

optimal device performance.

Power Supplies and Grounding

The MAX1172 requires -5.2V and +5V analog supply

supply line reduces the transient noise injected into the

close to the device as possible. The connection

between the beads and the MAX1172 should not be

shared with any other device. Bypass each power-sup-

ply pin as close to the device as possible. Use 0.1µF

are preferred).
