Описание

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).
