LTC1743

12-Bit, 50Msps ADC

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 0.3ps_RMSallows 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)

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.
