Low Power 3V ADCs
The LTC
2253/LTC2252 are 12-bit 125Msps/105Msps,
low power 3V A/D converters designed for digitizing high
frequency, wide dynamic range signals. The LTC2253/
LTC2252 are perfect for demanding imaging and commu-
nications applications with AC performance that includes
70.1dB SNR and 85dB SFDR for signals at the Nyquist
frequency.
DC specs include
±0.3LSB INL (typ), ±0.15LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 0.32LSBRMS.
A single 3V supply allows low power operation. A separate
output supply allows the outputs to drive 0.5V to 3.3V
logic.
A single-ended CLK input controls converter operation. An
optional clock duty cycle stabilizer allows high perfor-
mance at full speed for a wide range of clock duty cycles.
