DESCRIPTION
The TSA1001 is a 10-bit, 25Msps sampling fre-
quency Analog to Digital converter using a CMOS
technology combining high performances and
very low power consumption.
The TSA1001 is based on a pipeline structure and
digital error correction to provide excellent static
linearity and go beyond 9.8 effective bits at
Fs=25Msps, and Fin=10MHz.
Especially designed for portable applications, the
TSA1001 only dissipates 35mW at 25Msps. When
running at lower sampling frequencies, even lower
consumption can be achieved.
A voltage reference is integrated in the circuit to
simplify the design and minimize external compo-
nents. It is nevertheless possible to use the circuit
with an external reference.
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 synchro-
nization purposes.
The TSA1001 is available in commercial (0 to
+70°C) and extended (-40 to +85°C) temperature
range, in a small 48 pins TQFP package.
