LTC2234

10-Bit, 135Msps ADC

FEATURES

DESCRIPTIO

The LTC^®2234 is a 135Msps, sampling 10-bit A/D con-

verter designed for digitizing high frequency, wide dy-

namic range signals. The LTC2234 is perfect for demand-

ing communications applications with AC performance

that includes 60.5dB SNR and 75dB spurious free dy-

namic range for signals up to 400MHz. Ultralow jitter of

0.15ps_RMSallows undersampling of IF frequencies with

excellent noise performance.

■

Sample Rate: 135Msps

■

61dB SNR up to 200MHz Input

■

75dB SFDR up to 400MHz Input

■

775MHz Full Power Bandwidth S/H

■

Single 3.3V Supply

■

Low Power Dissipation: 630mW

■

CMOS Outputs

■

Selectable Input Ranges: ±0.5V or ±1V

■

No Missing Codes

DC specs include ±0.2LSB INL (typ), ±0.1LSB DNL (typ)

and ±0.8LSB INL, ±0.6LSB DNL over temperature. The

transition noise is a low 0.12LSB_RMS

■

Optional Clock Duty Cycle Stabilizer

■

Shutdown and Nap Modes

■

Data Ready Output Clock

■

A separate output power supply allows the CMOS output

swing to range from 0.5V to 3.6V.

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 ENC^–inputs 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.
