PIN CONNECTIONS (top view) D0 (LSB) DESCRIPTION GNDBE The TSA1401 is a 14-bit, 20MHz sampling frequency Analog to Digital Converter using deep submicron CMOS technology bining high performances with very low power consumption.The TSA1401 is based on a pipeline structure with digital error correction to provide excellent static linearity and dynamic performances. Typically designed for multi-channel applications and high-end imaging equipment, where low consumption is a must, the TSA1401 only dissipates 85m W at 20Msps when using external references, 110m W using internal references. Its power consumption adapts relative to sampling frequency. Differential signals are applied on the inputs for optimum performance. The TSA1401 reaches an SFDR of -90.5d Bc and an SNR of 73.1d Bc at Fin=10MHz when increasing the input dynamic range to 2.5V by using the voltage reference, TS431 (1.24V). A tri-state capability is available on the output buffers, enabling a Chip Select.The TSA1401 is available in the industrial temperature range of 40°C to...
