4 / 27 page ADC10040 SNAS224M – JULY 2003 – REVISED APRIL 2013 www.ti.com Pin Descriptions and Equivalent Circuits (continued) Pin No. Symbol Equivalent Circuit Description 16–20, Digital output data. D0 is the LSB and D9 is the MSB of the binary D0–D9 23–27 output word. ANALOG POWER Positive analog supply pins. These pins should be connected to a quiet 3,0V source and bypassed to analog ground with a 0.1 µF 2, 9, 10 VDDA monolithic capacitor located within 1 cm of these pins. A 4.7 µF capacitor should also be used in parallel. 3, 11, 14 VSSA Ground return for the analog supply. DIGITAL POWER Positive digital supply pins for the ADC10040’s output drivers. This pin should be bypassed to digital ground with a 0.1 µF monolithic 22 VDDIO capacitor located within 1 cm of this pin. A 4.7 µF capacitor should also be used in parallel. The voltage on this pin should never exceed the voltage on VDDA by more than 300 mV. The ground return for the digital supply for the output drivers. This 21 VSSIO pin should be connected to the ground plane, but not near the analog circuitry. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 4 Submit Documentation Feedback Copyright © 2003–2013, Texas Instruments Incorporated Product Folder Links: ADC10040 |
