16-Bit, 25Msps/10Msps ADC
The LTC2203/LTC2202 are 25Msps/10Msps, sampling
16-bitA/Dconvertersdesignedfordigitizinghighfrequen-
cy, wide dynamic range signals with input frequencies up
to 400MHz. The input range of the ADC can be optimized
with the PGA front end.
The LTC2203/LTC2202 are perfect for demanding ap-
plications, with AC performance that includes 81.4dB
SNR and 100dB spurious free dynamic range (SFDR).
Maximum DC specs include ±4LSB INL, ±1LSB DNL (no
missing codes).
A separate output power supply allows the CMOS output
swing to range from 0.5V to 3.6V.
A single-ended CLK input controls converter operation. An
optionalclockdutycyclestabilizerallowshighperformance
at full speed with a wide range of clock duty cycles.
