GENERAL 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 that provides
high input impedance and gain and drives the AD8138 single-
to-differential amplifier. The AD6644s have on-chip track-and-
hold circuitry and utilize an innovative multipass architecture
to achieve 14-bit, 65 MSPS performance.

Dual Channel, 14-Bit, 65 MSPS A/D Converter
with Analog Input Signal Conditioning
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 supplies for the analog
signal conditioning 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 further minimize additional external signal
conditioning, while remaining general-purpose.
The AD10465 is packaged in a 68-lead ceramic leaded chip
carrier package, footprint-compatible with the earlier
generation AD10242 (12-bit, 40 MSPS) and AD10265 (12-bit,
65 MSPS). Manufacturing is done on the Analog Devices 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’ high
speed complementary bipolar process (XFCB).
