TYPICAL APPLICATION
DESCRIPTION
Dual 12-Bit, 105Msps
Low Power 3V ADC
The LTC2282 is a 12-bit 105Msps, low power dual 3V
A/D converter designed for digitizing high frequency,
wide dynamic range signals. The LTC2282 is perfect for
demanding imaging and communications applications
with AC performance that includes 70.1dB SNR and 85dB
SFDR for signals at the Nyquist frequency.
DC specs include ±0.4LSB INL (typ), ±0.2LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 0.3LSBRMS.
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.
