DESCRIPTION
The TSA1401 is a 14-bit, 20MHz sampling
frequency Analog to Digital Converter using deep
submicron CMOS technology combining high
performances
with
very
low
power
consumption.The TSA1401 is based on a pipeline
structure with digital error correction to provide
excellent
static
linearity
and
dynamic
performances.
Typically designed for multi-channel applications
and high-end imaging equipment, where low
consumption is a must, the TSA1401 only
dissipates 85mW at 20Msps when using external
references, 110mW using internal references. Its
power consumption adapts relative to sampling
frequency. Differential signals are applied on the
inputs for optimum performance. The TSA1401
reaches an SFDR of -90.5dBc and an SNR of
73.1dBc at Fin=10MHz when increasing the input
dynamic range to 2.5V by using the voltage
reference, TS431 (1.24V).
A tri-state capability is available on the output
buffers, enabling a Chip Select.The TSA1401 is
available in the industrial temperature range of -
40°C to +85°C and in a small 48-lead TQFP
package.
