4 / 22 page ADC10662, ADC10664 SNAS076E – JUNE 1999 – REVISED MARCH 2013 www.ti.com Converter Characteristics The following specifications apply for V + = +5V, V REF(+) = +5V, VREF( −) = GND, and Speed Adjust pin connected to ground through a 14.0 k Ω resistor (Mode 1) or an 8.26 kΩ resistor (Mode 2) unless otherwise specified. Boldface limits apply for TA = TJ = TMin to TMax; all other limits TA = TJ = +25°C.

(2) Tested limits are ensured to AOQL (Average Outgoing Quality Level). (3) THD, SNR, and ENOB are tested in Mode 1. Measuring these quantities in Mode 2 yields similar values. 4 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: ADC10662 ADC10664 |
