The TSA1204 is specifically designed for applications requiring very low noise floor, high SFDR and good isolation between channels. It is based on a pipeline structure and digital error correction to provide excellent static linearity and over 11.2 effective bits at Fs=20Msps, and Fin=10MHz. For each channel, a voltage reference is integrated to simplify the design and minimize external components. ...
