DESCRIPTION
Dual 14-Bit, 135Msps
Low Power 3.3V ADC
The LTC
2285IUP#3CGPBF is a 14-bit 135Msps, low
power dual 3.3V A/D converter designed for digitiz-
ing high frequency, wide dynamic range signals. The
LTC2285IUP#3CGPBF is perfect for demanding imaging
and communications applications with AC performance
that includes 72.2dB SNR and 82dB 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 3.3V 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.
A data ready output clock (CLKOUT) can be used to latch
the output data.
