FEATURES  
DESCRIPTIO  
The LTC®2229 is a 12-bit 80Msps, low power 3V A/D  
converter designed for digitizing high frequency, wide  
dynamic range signals. The LTC2229 is perfect for de-  
manding imaging and communications applications with  
AC performance that includes 70.6dB SNR and 90dB  
SFDR for signals well beyond the Nyquist frequency.  
Sample Rate: 80Msps  
Single 3V Supply (2.7V to 3.4V)  
Low Power: 211mW  
70.6dB SNR at 70MHz Input  
90dB SFDR at 70MHz Input  
No Missing Codes  
Flexible Input: 1VP-P to 2VP-P Range  
DC specs include ±0.4LSB INL (typ), ±0.2LSB DNL (typ)  
575MHz Full Power Bandwidth S/H  
and no missing codes over temperature. The transition  
Clock Duty Cycle Stabilizer  
noise is a low 0.3LSBRMS  
.
Shutdown and Nap Modes  
A single 3V supply allows low power operation. A separate  
output supply allows the outputs to drive 0.5V to 3.6V  
logic.  
Pin Compatible Family  
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)
