TSA1204 DUAL CHANNEL
The TSA1204 is a new generation of high speed, dual-channel analog-to-digital converters implemented in a mainstream 0.25μm CMOS technology yielding high performance and very low power consumption.
The TSA1204 is specifically designed for applications requiring very low noise floor, high SFDR and good insulation 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=20 Msps, and Fin=10 MHz.
For each channel, an integrated voltage reference simplifies the design and minimizes external components. It is nevertheless possible to use the circuit with external references.
The ADC outputs are multiplexed in a common bus with a small number of pins. A tri-state capability is available for the outputs, allowing chip selection.
The inputs of the ADC must be differentially driven.
The TSA1204 is available in extended (-40˚ C to +85˚ C) temperature range, in a small 48-pin TQFP package
