FEATURES  
DESCRIPTIO  
The LTC®1743 is a 50Msps, sampling 12-bit A/D con-  
verter designed for digitizing high frequency, wide  
dynamicrangesignals.Pinselectableinputrangesof ±1V  
and ±1.6V along with a resistor programmable mode  
allow the LTC1743’s input range to be optimized for a  
wide variety of applications.  
Sample Rate: 50Msps  
72.5dB SNR and 85dB SFDR (3.2V Range)  
71dB SNR and 90dB SFDR (2V Range)  
No Missing Codes  
Single 5V Supply  
Power Dissipation: 1000mW  
Selectable Input Ranges: ±1V or ±1.6V  
The LTC1743 is perfect for demanding communications  
applications with AC performance that includes 72.5dB  
SNRand85dBspuriousfreedynamicrange.Ultralowjitter  
of 0.3psRMS allows undersampling of IF frequencies with  
excellent noise performance. DC specs include ±1LSB  
maximum INL and ±0.8LSB DNL over temperature.  
150MHz Full Power Bandwidth S/H  
Pin Compatible Family  
25Msps: LTC1746 (14-Bit), LTC1745 (12-Bit)  
50Msps: LTC1744 (14-Bit), LTC1743 (12-Bit)  
65Msps: LTC1742 (14-Bit), LTC1741 (12-Bit)  
80Msps: LTC1748 (14-Bit), LTC1747 (12-Bit)  
Thedigitalinterfaceiscompatiblewith5V, 3Vand2Vlogic  
systems. The ENC and ENC inputs may be driven differen-  
tiallyfromPECL, GTLandotherlowswinglogicfamiliesor  
from single-ended TTL or CMOS. The low noise, high gain  
ENC and ENC inputs may also be driven by a sinusoidal  
signal without degrading performance. A separate output  
power supply can be operated from 0.5V to 5V, making it  
easy to connect directly to any low voltage DSPs or FIFOs.
