GENERAL INTRODUCTION
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.
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.
