LTC2246H  
14-Bit, 25Msps  
125°C ADC In TQFP  
FEATURES  
DESCRIPTION  
The LTC®2246H is a 14-bit 25Msps, low power 3V A/D  
converter designed for digitizing high frequency, wide  
dynamic range signals. The LTC2246H is perfect for  
demanding imaging and communications applications  
with AC performance that includes 74.5dB SNR and 90dB  
SFDR.  
Sample Rate: 25Msps  
–40°C to 125°C Operation  
Single 3V Supply (2.8V to 3.5V)  
Low Power: 75mW  
74.5dB SNR  
90dB SFDR  
No Missing Codes  
Flexible ꢀnput: 1V to 2V Range  
575MHz Full Power Bandwidth S/H  
Clock Duty Cycle Stabilizer  
Shutdown and Nap Modes  
Pin Compatible Family  
DC specs include 1LSB ꢀNL ꢁtypꢂ, 0.5LSB DNL ꢁtypꢂ  
and no missing codes over temperature. The transition  
P-P  
P-P  
noise is a low 1LSB  
.
RMS  
A single 3V supply allows low power operation. A separate  
output supply allows the outputs to drive 0.5V to 3.6V  
logic.
