Low Power 3V ADCs
The LTC
2255/LTC2254 are 14-bit 125Msps/105Msps,
low power 3V A/D converters designed for digitizing high
frequency, wide dynamic range signals. The LTC2255/
LTC2254 are perfect for demanding imaging and commu-
nications applications with AC performance that includes
72.3dB SNR and 85dB SFDR for signals at the Nyquist
frequency.
DC specs include
±1LSB INL (typ), ±0.5LSB DNL (typ) and
no missing codes over temperature. The transition noise
is a low 1.3 LSBRMS.
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.
