The TSA1001 is based on a pipeline structure and digital error correction to provide excellent static linearity and go beyond 9.8 effective bits at Fs=25Msps, and Fin=10MHz. Especially designed for portable applications, the TSA1001 only dissipates 35mW at 25Msps. When running at lower sampling frequencies, even lower consumption can be achieved. A voltage reference is integrated in the circuit to simplify the design and minimize external compo- nents. It is nevertheless possible to use the circuit with an external reference. The output data can be coded into two different formats. A Data Ready signal is raised as the data is valid on the output and can be used for synchro- nization purposes. The TSA1001 is available in commercial (0 to +70°C) and extended (-40 to +85°C) temperature range, in a small 48 pins TQFP package.
