The ADS5481/ADS5482/ADS5483 (ADS548x) is a 16-bit family of analog-to-digital converters (ADCs) that

operate from both a 5-V supply and 3.3-V supply while providing LVDS-compatible digital outputs. The ADS548x

integrated analog input buffer isolates the internal switching of the onboard track and hold (T&H) from disturbing

the signal source while providing a high-impedance input. An internal reference generator is also provided to

simplify the system design.

Designed for highest total ENOB, the ADS548x family has outstanding low noise performance and spurious-free

dynamic range.

The ADS548x is available in an QFN-64 PowerPAD package. The device is built on Texas Instruments

complementary bipolar process (BiCom3) and is specified over the full industrial temperature range (–40°C to

+85°C).
