PRODUCT DESCRIPTION
The AD10465 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 AD6644 ADCs. Each AD6644 has a dc-
coupled amplifier front end including an AD8037 low distortion,
high bandwidth amplifier, providing a high input impedance
and gain, and driving the AD8138 single-to-differential ampli-
fier. The AD6644s have on-chip track-and-hold circuitry and
utilize an innovative multipass architecture to achieve 14-bit,
65 MSPS performance. The AD10465 uses innovative high-
density circuit design and laser-trimmed thin-film resistor networks
to achieve exceptional matching and performance, while still
maintaining excellent isolation and providing for significant
board area savings.
The AD10465 operates with
±5.0 V for the analog signal condi-
tioning with a separate 5.0 V supply for the analog-to-digital
conversion and 3.3 V digital supply for the output stage. Each
channel is completely independent, allowing operation with
independent encode and analog inputs. The AD10465 also
offers the user a choice of analog input signal ranges to fur-
ther minimize additional external signal conditioning, while
still remaining general-purpose.
The AD10465 is packaged in a 68-lead Ceramic Gull Wing
package, footprint-compatible with the earlier generation AD10242
(12-bit, 40 MSPS) and AD10265 (12-bit, 65 MSPS). Manufac-
turing is done on Analog Devices, Inc. Mil-38534 Qualified
Manufacturers Line (QML) and components are available up to
Class-H (–40
°C to +85°C). The AD6644 internal components
are manufactured on Analog Devices, Inc. high-speed comple-
mentary 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.
5. Footprint compatible family; 68-lead LCC.
