DESCRIPTION
The TSA1203 is a new generation of high speed,
dual-channel Analog to Digital converter pro-
cessed in a mainstream 0.25碌m CMOS technolo-
gy yielding high performances and very low power
consumption.
The TSA1203 is specifically designed for applica-
tions 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 high static linearity at Fs=40Msps, and
Fin=10MHz.
For each channel, a voltage reference is integrat-
ed 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 capabili-
ty is available for the outputs, allowing chip selec-
tion. The inputs of the ADC must be differentially
driven.
The TSA1203 is available in extended (0 to
+85擄C) temperature range, in a small 48 pins
TQFP package.
