GENERAL INTRODUCTION

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

converter with an on-chip track-and-hold circuit and is optimized

for high-speed conversion and ease of use. The product operates

at a 105 MSPS conversion rate with outstanding dynamic per-

formance 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 reference 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 and is TTL/CMOS-compatible.

Fabricated on an advanced BiCMOS process, the AD9432 is

available in a 52-lead plastic quad flatpack package (LQFP)

specified over the industrial temperature range (–40 C to

+85 C).
