12-Bit, 80 MSPS/105 MSPS ADC

AD9432

FEATURES

GENERAL INTRODUCTION

On-chip reference and track-and-hold

On-chip input buffer

Power dissipation: 850 mW typical at 105 MSPS

500 MHz analog bandwidth

SNR: 67 dB @ 49 MHz AIN at 105 MSPS

SFDR: 80 dB @ 49 MHz AIN at 105 MSPS

2.0 V p-p analog input range

5.0 V supply operation

3.3 V CMOS/TTL outputs

Twos complement output format

The AD9432 is a 12-bit, monolithic sampling analog-to-digital

converter (ADC) with an on-chip track-and-hold circuit and is

optimized for high speed conversion and ease of use. The prod-

uct operates up to a 105 MSPS conversion rate with outstanding

dynamic performance over its full operating range.

The ADC requires only a single 5.0 V power supply and a 105 MHz

encode clock for full performance operation. No external refer-

ence or driver components are required for many applications.

The digital outputs are TTL-/CMOS-compatible, and a separate

output power supply pin supports interfacing with 3.3 V logic.

The encode input supports either differential or single-ended

mode and is TTL-/CMOS-compatible.

APPLICATIONS

Communications

Base stations and zero-IF subsystems

Wireless local loop (WLL)

Local multipoint distribution service (LMDS)

HDTV broadcast cameras and film scanners

Fabricated on an advanced BiCMOS process, the AD9432 is

available in a 52-lead low profile quad flat package (LQFP) and

in a 52-lead thin quad flat package (TQFP_EP). The AD9432 is

specified over the industrial temperature range of −40°C to +85°C.
