DESCRIPTION
The ADS54T02 is a high linearity dual 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).
