The
new ADS527x line of products from Texas Instruments is a family
of 8-channel, 10- and 12-bit, 40/50/65 and 70 MSPS ADCs featuring
serial LVDS outputs. The family delivers the lowest power
operation of any 70.5dB SNR ADC at these sampling rates. The
combination of high integration and ultra-low power make these
devices ideally suited for high
density, multi-channel applications like ultrasound, wireless
communications, optical networking, instrumentation, test
and measurement, and a variety of other multi-channel applications.
The
ADS527x family is also optimized to work with TI’s high-performance
TMS320C6000™ DSP platform and with many of TI’s
high-speed op amps to achieve highest performance.
