LTC2222-11  
11-Bit, 105Msps ADC  
U
FEATURES  
DESCRIPTIO  
The LTC®2222-11 is a 105Msps, sampling 11-bit A/D  
converter designed for digitizing high frequency, wide  
dynamic range signals. The LTC2222-11 is perfect for  
demanding communications applications with AC perfor-  
mance that includes 65.4dB SNR and 80dB spurious free  
dynamic range for signals up to 150MHz. Ultralow jitter of  
0.15psRMS allows undersampling of IF frequencies with  
excellent noise performance.  
Sample Rate: 105Msps  
65.4dB SNR up to 140MHz Input  
80dB SFDR up to 150MHz Input  
775MHz Full Power Bandwidth S/H  
Single 3.3V Supply  
Low Power Dissipation: 475mW  
CMOS Outputs  
Selectable Input Ranges: ±0.5V or ±1V  
No Missing Codes  
DC specs include ±0.15LSB INL (typ), ±0.1LSB DNL (typ)  
Optional Clock Duty Cycle Stabilizer  
and no missing codes over temperature. The transition  
Shutdown and Nap Modes  
noise is a low 0.25LSBRMS  
.
Data Ready Output Clock  
A separate output power supply allows the CMOS output  
swing to range from 0.5V to 3.3V.  
Pin Compatible Family  
135Msps: LTC2224 (12-Bit), LTC2234 (10-Bit)  
105Msps: LTC2222 (12-Bit), LTC2232 (10-Bit)  
80Msps: LTC2223 (12-Bit), LTC2233 (10-Bit)  
48-Pin 7mm × 7mm QFN Package  
The ENC+ and ENCinputs may be driven differentially or  
singleendedwithasinewave, PECL, LVDS, TTL, orCMOS  
inputs. An optional clock duty cycle stabilizer allows high  
performance at full speed for a wide range of clock duty  
cycles.
