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). 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
