LTC2284 双通道 14 位、105Msps 低功率 3V ADC

The LTC®2284 is a 14-bit 105Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2284 is perfect for demanding imaging and communications applications with AC performance that includes 72.4dB SNR and 85dB SFDR for signals at the Nyquist frequency.

Typical DC specs include ±1.5LSB INL, ±0.6LSB DNL. The transition noise is a low 1.3LSBRMS.

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
