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 1LSB

RMS

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.
