1) OPTIMWATT(TM) is a ST deposited trademark for products features allowing optimization of power efficiency at chip/application level.

The TSA1401 is a 14-bit, 20MHz sampling frequency Analog to Digital Converter using deep submicron CMOS technology combining 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 85mW at 20Msps when using exter al references, 110mW 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 -90.5dBc and an SNR of 73.1dBc 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 +85°C and in a small 48-lead TQFP package.
