6 / 44 page  ADC101C021, ADC101C027 SNAS446D – FEBRUARY 2008 – REVISED FEBRUARY 2013 www.ti.com Electrical Characteristics The following specifications apply for VA = +2.7V to +5.5V, GND = 0V, fSCL up to 3.4MHz, fIN = 1kHz for fSCL up to 400kHz, fIN = 10kHz for fSCL = 3.4MHz unless otherwise noted. Boldface limits apply for TA = TMIN to TMAX: all other limits TA = 25°C unless otherwise noted.

Test limits are guaranteed to National's AOQL (Average Outgoing Quality Level). (2) The ADC will meet Minimum/Maximum specifications for fSCL up to 3.4MHz when operating in the Quiet Interface Mode (Section 1.11). (3) This parameter is guaranteed by design and/or characterization and is not tested in production. 6 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: ADC101C021 ADC101C027 |
