TSA1203 - Dual-channel 12-bit 40Msps 215mW A/D converter

General Description

The TSA1203 is a new generation high-speed, dual-channel analog-to-digital converter implemented in a mainstream 0.25 µm CMOS technology that offers high performance and very low power consumption.

The TSA1203 is specifically designed for applications requiring a very low noise floor, high SFDR and good insulation between channels.

It is based on a pipeline structure and digital error correction to provide high static linearity at FS = 40 Msps, and Fin = 10 MHz.
