Data Sheet
Dual Channel, 14-Bit, 65 MSPS A/D Converter
with Analog Input Signal Conditioning
AD10465
FEATURES
Dual, 65 MSPS minimum sample rate
Channel-to-channel matching, ±0.5% gain error
Channel-to-channel isolation, >90 dB
DC-coupled signal conditioning included
Selectable bipolar input voltage range
(±0.5 V, ±1.0 V, ±2.0 V)
Gain flatness up to 25 MHz: <0.2 dB
80 dB spurious-free dynamic range
Twos complement output format
3.3 V or 5 V CMOS-compatible output levels
1.75 W per channel
Industrial and military grade
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.
APPLICATIONS
Phased array receivers
Communications receivers
FLIR processing
Secure communications
GPS antijamming receivers
Multichannel, multimode receivers
GENERAL DESCRIPTION
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).
The AD10465 is a full channel ADC solution with on-module
