DESCRIPTION
The TSA0801 is an 8-bit, 40MHz sampling fre-
quency Analog to Digital converter using a deep
submicron CMOS technology combining high per-
formances and very low power consumption.
The TSA0801 is based on a pipeline structure and
digital error correction to provide excellent static
linearity and go beyond 7.9 effective bits at
Fs=40Msps, and Fin=10MHz.
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.
Differential or single-ended analog inputs can be
applied to the converter. A tri-state capability is
available on the outputs. 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 TSA0801 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.
