Hot-selling and scarce TSA1204IFT DUAL-CHANNEL, 12-BIT, 20MSPS, 120mW A/D CONVERTER QFP48

Product Descriptions

The TSA1204 is a new generation of high speed, dual-channel Analog to Digital converter processed in a mainstream 0.25µm CMOS technology yielding high performances and very low power consumption.

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. It is nevertheless possible to use the circuit with external references.

Each ADC outputs are multiplexed in a common bus with 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 to +85°C) temperature range, in a small 48 pins TQFP package.
