N ^c DESCRIPTION
du The TSA1002 is a 10-bit, 50Msps sampling
R ^{ro frequency Analog to Digital converter using a}
CMOS technology combining high performances
P _{and very low power consumption.}
O ^{te The TSA1002 is based on a pipeline structure and}
le ^{digital error correction to provide excellent static}
F ^{o linearity and guarantee 9.6 effective bits at}
s _{Fs=40Msps, and Fin=24MHz.}
b _{A voltage reference is integrated in the circuit to}
T ^{O simplify the design and minimize external}
- _{components. It is nevertheless possible to use the}
) _{circuit with an external reference.}
O _{t(s Especially designed for high speed, low power}
c ^{applications, the TSA1002 only dissipates 50mW}
N u at 50Msps. A tri-state capability, available on the
d _{output buffers, enables to address several slave}
ro ^{ADCs by a unique master.}
P ^{The output data can be coded into two different}
formats. A Data Ready signal is raised as the data
te _{is valid on the output and can be used for}
le ^{synchronization purposes.}
o The TSA1002 is available in commercial (0 to
s_{+70 C) and extended (-40 to +85 C) temperature}
Ob^{range, in a small 48 pins TQFP package.}
