12-Bit, 80 MSPS/105 MSPS ADC AD9432 FEATURES GENERAL INTRODUCTION On-chip reference and track-and-hold
The AD9432 is a 12-bit, monolithic sampling analog-to-digital
On-chip input buffer
converter (ADC) with an on-chip track-and-hold circuit and is
Power dissipation: 850 mW typical at 105 MSPS
optimized for high speed conversion and ease of use. The prod-
500 MHz analog bandwidth
uct operates up to a 105 MSPS conversion rate with outstanding
SNR: 67 dB @ 49 MHz AIN at 105 MSPS
dynamic performance over its full operating range.
SFDR: 80 dB @ 49 MHz AIN at 105 MSPS
The ADC requires only a single 5.0 V power supply and a 105 MHz
2.0 V p-p analog input range
encode clock for full performance operation. No external refer-
5.0 V supply operation
ence or driver components are required for many applications.
3.3 V CMOS/TTL outputs
The digital outputs are TTL-/CMOS-compatible, and a separate
Twos complement output format
output power supply pin supports interfacing with 3.3 V logic.
APPLICATIONS
The encode input supports either differential or single-ended
Communications
mode and is TTL-/CMOS-compatible.
Base stations and zero-IF subsystems
Fabricated on an advanced BiCMOS process, the AD9432 is
Wireless local loop (WLL)
available in a 52-lead low profile quad flat package (LQFP) and
Local multipoint distribution service (LMDS)
in a 52-lead thin quad flat package (TQFP_EP). The AD9432 is
HDTV broadcast cameras and film scanners
specified over the industrial temperature range of −40°C to +85°C.
