DESCRIPTION
The TSA1002 is a 10-bit, 50Msps sampling
frequency Analog to Digital converter using a
CMOS technology combining high performances
and very low power consumption.
The TSA1002 is based on a pipeline structure and
digital error correction to provide excellent static
linearity and guarantee 9.4 effective bits at
Fs=50Msps, and Fin=15MHz.
A voltage reference is integrated in the circuit to
simplify the design and minimize external
components. It is nevertheless possible to use the
circuit with an external reference.
Especially designed for high speed, low power
applications, the TSA1002 only dissipates 50mW
at 50Msps. A tri-state capability, available on the
output buffers, enables to address several slave
ADCs by a unique master.
The output data can be coded into two different
formats. A Data Ready signal is raised as the data
is valid on the output and can be used for
synchronization purposes.
The TSA1002 is available in commercial (0 to
+70擄C) and extended (-40 to +85擄C) temperature
range, in a small 48 pins TQFP package.
