Product data sheet
Fig 10. Application diagram
(1) These capacitors must have a low ESR and must be placed near the IC (less than 1 cm).
(2) One 100 nF with low ESR near pin 17.
(3) One 100 nF or 220 nF with low ESR near contact C1 (less than 1 cm).
(4) Contact C3 should be routed far from contacts C2, C7, C4 and C8 and, better, surrounded with ground tracks.
(5) Straight and short connections between pin CGND, contact C5 and ground for the capacitors (no loop).
