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 – it 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
196pin BGA package and is specified over the full industrial temperature range (–40°C to 85°C).
