FEATURES  
DESCRIPTIO  
The LTC®2248/LTC2247/LTC2246 are 14-bit 65Msps/  
40Msps/25Msps, low power 3V A/D converters designed  
for digitizing high frequency, wide dynamic range signals.  
The LTC2248/LTC2247/LTC2246 are perfect for demand-  
ing imaging and communications applications with AC  
performance that includes 74.3dB SNR and 90dB SFDR  
for signals at the Nyquist frequency.  
Sample Rate: 65Msps/40Msps/25Msps  
Single 3V Supply (2.7V to 3.4V)  
Low Power: 205mW/120mW/75mW  
74.3dB SNR  
90dB SFDR  
No Missing Codes  
Flexible Input: 1VP-P to 2VP-P Range  
575MHz Full Power Bandwidth S/H  
DCspecsinclude±1LSBINL(typ), ±0.5LSBDNL(typ)and  
no missing codes over temperature. The transition noise
