DESCRIPTION
The TSA1005 belongs to a new generation of high
speed, dual-channel Analog to Digital converters,
processed in a mainstream 0.25 m CMOS tech-
nology and yielding high performances.
The TSA1005 is specifically designed for applica-
tions requiring a very low noise floor, high SFDR
and good isolation between channels. It is based
on a pipeline structure and digital error correction,
providing high static linearity at 20/40 Msp, and
Fin = 10 MHz.
For each channel, a voltage reference is integrat-
ed to simplify the design and minimize external
components. It is nevertheless possible to use the
circuit with external references.
Each ADC output is multiplexed on a common bus
with small number of pins. A tri-state capability is
available for the output signals, allowing for chip
selection. The input signals of the ADC must be
differentially driven.
The TSA1005 is supports an extended (0 to
+85 C) temperature range, and is available in the
small 48-pin TQFP package.
