3 Description

The ADS54T01 is a high linearity, single channel,

12-bit, 750-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.

Two output modes are available for the output data

—the data can be decimated by two or the data

can be output in burst mode. The burst mode

output is designed specifically for DPD feedback

applications where high-resolution output data is

available for a short period of time. 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 NFBGA package and is specified over the full

industrial temperature range (–40°C to 85°C).
