LTC2245 14-Bit, 10Msps Low Power 3V ADC

The LTC®2245 is a 14-bit 10Msps, low power 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2245 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 ±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 performance at full speed for a wide range of clock duty cycles
