SBAS653 – APRIL 2014 ADS4245-EP Dual-Channel, 14-Bit, 125MSPS Ultralow-Power ADC
1 Features 3 Description The ADS4245 is a low-speed variant of the ADS42xx
ultralow-power family of dual-channel, 14-bit analogto-digital converters (ADCs). Innovative design
techniques are used to achieve high-dynamic
performance, while consuming extremely low power
with 1.8V supply. This topology makes the ADS4245
well-suited
for
multi-carrier,
wide-bandwidth
communications applications. 1 Ultralow Power with Single 1.8V Supply,
CMOS Output:
– 277mW total power at 125MSPS
High Dynamic Performance:
– 88dBc SFDR at 170MHz
– 71.4dBFS SNR at 170MHz
Crosstalk: > 90dB at 185MHz …
