Typical Application
Description
The LTC2280 is a 10-bit 105Msps, low noise 3V dual A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2280 is perfect for demanding imaging and communications applications with AC performance that includes 61.6dB SNR and 85dB SFDR for signals at the Nyquist frequency.DC specs include ±0.1LSB INL (typ), ±0.1LSB DNL (typ) and ±0.6LSB INL, ±0.6LSB DNL over temperature. 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.
