FEATURES  
DESCRIPTIO  
The LTC®2253/LTC2252 are 12-bit 125Msps/105Msps,  
low power 3V A/D converters designed for digitizing high  
frequency, wide dynamic range signals. The LTC2253/  
LTC2252 are perfect for demanding imaging and commu-  
nications applications with AC performance that includes  
70.1dB SNR and 85dB SFDR for signals at the Nyquist  
frequency.  
Sample Rate: 125Msps/105Msps  
Single 3V Supply (2.85V to 3.4V)  
Low Power: 395mW/320mW  
70.2dB SNR  
88dB SFDR  
No Missing Codes  
Flexible Input: 1VP-P to 2VP-P Range  
640MHz Full Power Bandwidth S/H  
DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ)  
Clock Duty Cycle Stabilizer  
and no missing codes over temperature. The transition  
Shutdown and Nap Modes  
noise is a low 0.32LSBRMS  
.
Pin Compatible Family  
A single 3V supply allows low power operation. A separate  
output supply allows the outputs to drive 0.5V to 3.3V  
logic.  
125Msps: LTC2253 (12-Bit), LTC2255 (14-Bit)  
105Msps: LTC2252 (12-Bit), LTC2254 (14-Bit)  
80Msps: LTC2229 (12-Bit), LTC2249 (14-Bit)  
65Msps: LTC2228 (12-Bit), LTC2248 (14-Bit)  
40Msps: LTC2227 (12-Bit), LTC2247 (14-Bit)  
25Msps: LTC2226 (12-Bit), LTC2246 (14-Bit)  
10Msps: LTC2225 (12-Bit), LTC2245 (14-Bit)  
Asingle-endedCLKinputcontrolsconverteroperation.An  
optional clock duty cycle stabilizer allows high perfor-  
mance at full speed for a wide range of clock duty cycles.
