PRODUCT DESCRIPTION
The AD10265 is a full channel ADC solution with on-module
signal conditioning for improved dynamic performance and
fully matched channel-to-channel performance. The module
includes two wide dynamic range AD6640 ADCs. Each AD6640
has an AD9631/AD9632 ac-coupled amplifier front end. The
AD6640s have on-chip track-and-hold circuitry, and utilize an
innovative multipass architecture, to achieve 12-bit, 65 MSPS
performance. The AD10265 uses innovative high-density
circuit design and laser-trimmed thin-film resistor networks to
achieve exceptional matching and performance while still main-
taining excellent isolation, and providing for significant board
area savings.
The AD10265 operates with ± 5.0 V for the analog signal
conditioning with a separate +3.3 V supply for the analog-to-
digital conversion. Each channel is completely independent
allowing operation with independent Encode and Analog
inputs. The AD10265 also offers the user a choice of Analog
Input Signal ranges to further minimize additional external
signal conditioning, while still remaining general-purpose.
The AD10265 is packaged in a 68-lead ceramic gull wing pack-
age, footprint compatible with the earlier generation AD10242
(12-bit, 40 MSPS). Manufacturing is done on Analog Devices’
MIL-38534 Qualified Manufacturers Line (QML) and com-
ponents are available up to Class-T (–25°C to +125°C). The
AD6640 internal components are manufactured on Analog
Devices’ high-speed complementary bipolar process (XFCB).
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 65 MSPS.
2. Input amplitude options, user configurable.
3. Input signal conditioning included; both channels matched
for gain.
4. Fully tested/characterized performance for full channel.
5. Footprint compatible family; 68-lead LCCC.
