Low Power 3V ADCs
The LTC
2248/LTC2247/LTC2246 are 14-bit 65Msps/
40Msps/25Msps, low power 3V A/D converters designed
for digitizing high frequency, wide dynamic range signals.
The LTC2248/LTC2247/LTC2246 are perfect for demand-
ing imaging and communications applications with AC
performance that includes 74.3dB SNR and 90dB 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 1LSBRMS.
A single 3V supply allows low power operation. A separate
output supply allows the outputs to drive 0.5V to 3.6V
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.
