Dual 14-Bit, 105Msps
Low Power 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 perfor-
mance at full speed for a wide range of clock duty cycles.
