ADS5423-EP (Rev. C)
Texas Instruments
Description
The ADS5423 is a 14-bit 80-MSPS analog-to-digital converter (ADC) that operates from a 5-V supply, while providing 3.3-V CMOS-compatible digital outputs. The ADS5423 input buffer isolates the internal switching of the on-chip track and hold (T&H) from disturbing the signal source. An internal reference generator is also provided to further simplify the system design. The ADS5423 has outstanding low noise and linearity over input frequency. With only a 2.2-VPP input range, the device simplifies the design of multicarrier applications, where the carriers are selected on the digital domain.The ADS5423 is available in a 52-pin thermally-enhanced thin quad flat pack (HTQFP) with heatsink and is pin compatible to the AD6645. The ADS5423 is built on state-of-the-art Texas Instruments complementary bipolar process (BiCom3) and is specified over the full military temperature range (-55°C to 125°C).

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.PowerPAD is a trademark of Texas Instruments.
