6 / 41 page ADC081C021, ADC081C027 SNAS447C – FEBRUARY 2008 – REVISED MARCH 2013 www.ti.com Package Thermal Resistances (1) (2) Package θJA 6-Lead SOT 250°C/W 8-Lead VSSOP 200°C/W (1) Soldering process must comply with Reflow Temperature Profile specifications. Refer to www.ti.com/packaging. (2) Reflow temperature profiles are different for lead-free packages. 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 specified to AOQL (Average Outgoing Quality Level). (2) The ADC will meet Minimum/Maximum specifications for fSCL up to 3.4MHz and VA = 2.7V to 3.6V when operating in the QUIET INTERFACE MODE. (3) This parameter is specified by design and/or characterization and is not tested in production. 6 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: ADC081C021 ADC081C027 |
