LTC2281  
Dual 10-Bit, 125Msps  
Low Power 3V ADC  
FEATURES  
DESCRIPTION  
The LTC®2281 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.

64-Pin (9mm × 9mm) QFN Package  
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.
