PRODUCT DESCRIPTION
The AD10226 offers two complete ADC channels with on-module
signal conditioning for improved dynamic performance. Each wide
dynamic range ADC has a transformer coupled front end
optimized for direct-IF sampling. The AD10226 has on-chip
track-and-hold circuitry and utilizes an innovative architecture to
achieve 12-bit, 125 MSPS performance. The AD10226 uses
innovative high density circuit design to achieve exceptional
performance, while still maintaining excellent isolation and pro-
viding for board area savings.
The AD10226 operates with 5.0 V analog supply and 3.3 V digital
supply. Each channel is completely independent, allowing opera-
tion with independent ENCODE and analog inputs. The AD10226
is available in a 35 mm square 385-lead BGA package.
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 125 MSPS
2. Input signal conditioning included with full-power bandwidth
to 350 MHz
3. Industry-leading IF sampling performance
