cDESCRIPTION
duThe TSA1002 is a 10-bit, 50Msps sampling
rofrequency Analog to Digital converter using a
CMOS technology combining high performances
Pand very low power consumption.
teThe TSA1002 is based on a pipeline structure and
ledigital error correction to provide excellent static
olinearity and guarantee 9.6 effective bits at
sFs=40Msps, and Fin=24MHz.
bA voltage reference is integrated in the circuit to
Osimplify the design and minimize external
-components. It is nevertheless possible to use the
)circuit with an external reference.
t(sEspecially designed for high speed, low power
capplications, the TSA1002 only dissipates 50mW
uat 50Msps. A tri-state capability, available on the
doutput buffers, enables to address several slave
roADCs by a unique master.
PThe output data can be coded into two different
formats. A Data Ready signal is raised as the data
teis valid on the output and can be used for
lesynchronization purposes.
oThe TSA1002 is available in commercial (0 to
s+70 C) and extended (-40 to +85 C) temperature
Obrange, in a small 48 pins TQFP package.
