5 / 20 page ![]() Pin Descriptions and Equivalent Circuits (Continued) Digital Power 20 V D Positive digital supply pin. This pin should be connected to the same clean, quiet +5V source as is V A and bypassed to DGND with a 0.1 µF monolithic capacitor in parallel with a 10µF capacitor, both located within 1 cm of the power pin. 12, 13, 14, 19, 41, 42, 43 DGND The ground return for the digital supply. AGND and DGND should be connected together directly beneath the ADC16061 package. See Section 5 (Layout and Grounding) for more details. 34 V D I/O Positive digital supply pin for the ADC16061’s output drivers. This pin should be connected to a +3V to +5V source and bypassed to DGND I/O with a 0.1 µF monolithic capacitor. If the supply for this pin is different from the supply used for V A and VD, it should also be bypassed with a 10 µF capacitor. All bypass capacitors should be located within 1 cm of the supply pin. 33 DGND I/O The ground return for the digital supply for the ADC16061’s output drivers. This pin should be connected to the system digital ground, but not be connected in close proximity to the ADC16061’s DGND or AGND pins. See Section 5.0 (Layout and Grounding) for more details. NC 2, 3, 9, 15, 16, 39 NC All pins marked NC (no connect) should be left floating. Do not connect the NC pins to ground, power supplies, or any other potential or signal. These pins are used for test in the manufacturing process. www.national.com 5 |
