The ADS8504 is specified at a 250-kHz sampling rate
over the full temperature range. Precision resistors
provide an industry standard ±10-V input range, while
the innovative design allows operation from a single
+5-V supply, with power dissipation under 100 mW.
The ADS8504 is available in a 28-pin SOIC package
and is fully specified for operation over the industrial
-40°C to 85°C temperature range.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.
