The LTC

2295 is a 14-bit 10Msps, low power dual 3V

A/D converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2295 is perfect for

demanding imaging and communications applications

with AC performance that includes 74.4dB SNR and 90dB

SFDR for signals well beyond the Nyquist frequency.

DC specs include

±1.2LSB

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. An optional multiplexer allows both channels to

share a digital output bus.

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.
