Description

The LTC®2249 is a 14-bit 80Msps, low power 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2249 is perfect for demanding imaging and communications applications with AC performance that includes 73dB SNR and 90dB SFDR for signals well beyond 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 1.2LSBRMS.

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 of LTC2249 controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
