The LTC2281 is a 10-bit 125Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2281 is perfect for demanding imaging and communications applications with AC performance that includes 61.6dB SNR and 82dB SFDR for signals at the Nyquist frequency.
Typical DC specs include ±0.1LSB INL, ±0.1LSB DNL. The transition noise is a low 0.08LSBRMS.
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. A data ready output clock (CLKOUT) can be used to latch the output data.
