The LTC

2229 is a 12-bit 80Msps, low power 3V A/D

converter designed for digitizing high frequency, wide

dynamic range signals. The LTC2229 is perfect for de-

manding imaging and communications applications with

AC performance that includes 70.6dB SNR and 90dB

SFDR for signals well beyond the Nyquist frequency.

DC specs include

±0.4LSB

INL (typ),

±0.2LSB

DNL (typ)

and no missing codes over temperature. The transition

noise is a low 0.3LSB

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.
