The TSA1005 belongs to a new generation of high speed, dual-channel Analog to Digital converters, processed in a mainstream 0.25 m CMOS technology
and yielding high performances.
The TSA1005 is specifically designed for applications requiring a very low noise floor, high SFDR and good isolation between channels. It is based on a pipeline structure and digital error correction, providing high static linearity at 20/40 Msp, and Fin = 10 MHz.
For each channel, a voltage reference is integrated to simplify the design and minimize external components. It is nevertheless possible to use the circuit with external references.
Each ADC output is multiplexed on a common bus with small number of pins. A tri-state capability is available for the output signals, allowing for chip selection. The input signals of the ADC must be differentially driven.
The TSA1005 is supports an extended (0 to +85°C) temperature range, and is available in the small 48-pin TQFP package.
