DESCRIPTION
The TSA1201 is a 12-bit, 50MHz maximum
sampling frequency Analog to Digital converter
using a CMOS technology combining high
performances and very low power consumption.
The TSA1201 is based on a pipeline structure and
digital error correction to provide excellent static
linearity and achieve 10.5 effective bits at
Fs=50Msps, and Fin=15MHz, with a global power
consumption of 150mW.
The TSA1201 features adaptative behaviour to
the application. Its architecture allows to sample
from 0.5Msps up to 50Msps, with a programmable
power consumption which makes the application
board even more optimized.
It integrates a proprietary track-and-hold structure
to ensure an high analog bandwidth of 1GHz and
enable IF-sampling.
Several features are available on the device. A
voltage reference is integrated in the circuit.
Differential or single-ended analog inputs can be
applied. The output data can be coded into two
differential formats. A Data Ready signal is raised
as the data is valid on the output and can be used
for synchronization purposes.
The TSA1201 is available in extended (-40°C to
+85°C) temperature range, in small 48 pins TQFP
package.
APPLICATIONS
s High speed data acquisition
s Medical imaging and ultrasound
