3 Description
The ADS5401 device is a high-linearity single-
channel 12-bit, 800-Msps analog-to-digital converter
(ADC) easing front-end filter design for wide
bandwidth receivers. The analog input buffer isolates
the internal switching of the on-chip track-and-hold
from disturbing the signal source as well as providing
a high-impedance input. Optionally the output data
can be decimated by two. Designed for high SFDR,
the ADC has low-noise performance and outstanding
spurious-free dynamic range over a large input-
frequency range. The device is available in a 196-pin
BGA package and is specified over the full industrial
temperature range (–40°C to 85°C).
