LTC2228/LTC2227/LTC2226  
12-Bit, 65/40/25Msps  
Low Power 3V ADCs  
FEATURES  
DESCRIPTION  
The LTC®2228/LTC2227/LTC2226 are 12-bit 65Msps/  
40Msps/25Msps, low power 3V A/D converters designed  
for digitizing high frequency, wide dynamic range signals.  
The LTC2228/LTC2227/LTC2226 are perfect for demand-  
ing imaging and communications applications with AC  
performance that includes 71.3dB SNR and 90dB SFDR  
for signals at the Nyquist frequency.
