______________Detailed Description
The MAX1160 requires few external components to
achieve the stated operation and performance. Figure
2 shows the typical interface requirements when using
the MAX1160 in normal circuit operation. The following
section provides a description of the pin functions, and
outlines critical performance criteria to consider for
achieving the optimal device performance.
Power Supplies and Grounding
The MAX1160 requires -5.2V and +5V analog supply
voltages. The +5V supply is common to analog V_CC
and digital DV_CC. A ferrite bead in series with each
supply line reduces the transient noise injected into the
analog V_CC. Connect these beads as close to the
device as possible. The connection between the beads
and the MAX1160 should not be shared with any other
device. Bypass each power-supply pin as close to the
device as possible. Use 0.1µF for V_EE and V_CC, and
0.01µF for DV_CC (chip capacitors are recommended).
