DESCRIPTION
The ADS5440 is a 13-bit 210-MSPS analog-to-digital converter (ADC) that operates from a 5-V supply, while
providing LVDS-compatible digital outputs from a 3.3-V supply. The ADS5440 input buffer isolates the internal
switching of the onboard track and hold (T&H) from disturbing the signal source. An internal reference generator
is also provided to further simplify the system design. The ADS5440 has outstanding low noise and linearity over
input frequency.
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.

Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

    ... ADS5440-EP SGLS359 – AUGUST 2006 Power Supplies The use of low noise power supplies with adequate decoupling is recommended. Linear supplies are the preferred choice versus switched ones, which tend to generate more noise components that can be coupled to the ADS5440. The ADS5440 uses two power supplies. For the analog portion of the design, a 5-V AVDD is used, while for the digital outputs supply (DRVDD) we recommend the use of 3 ...
