state-of-the-art high-density circuit design and laser-trimmed
thin-film resistor networks to achieve exceptional channel
matching and impedance control, and provide for significant
board area savings.
Multiple options are provided for driving the analog input, includ-
ing single-ended, differential, and optional series filtering. The
AD13465 also offers the user a choice of analog input signal
ranges to further minimize additional external signal condition-
ing, while remaining general-purpose. The AD13465 operates
with ± 5.0 V for the analog signal conditioning, 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, allow-
ing operation with independent Encode and Analog Inputs, while
maintaining minimal crosstalk and interference.
The AD13465 is packaged in a 68-lead ceramic gull wing
package. Manufacturing is done on Analog Devices’ MIL-
38534 Qualified Manufacturers Line (QML) and components
are available up to Class-H (–40°C to +85°C). The components
are manufactured using Analog Devices’ high-speed comple-
mentary bipolar process (XFCB).
PRODUCT DESCRIPTION
The AD13465 is a complete dual channel signal processing
solution including on-board amplifiers, references, ADCs,
and output termination components to provide optimized
system performance. The AD13465 has on-chip track-and-hold
circuitry and utilizes an innovative multipass architecture to
achieve 14-bit, 65 MSPS performance. The AD13465 uses
PRODUCT HIGHLIGHTS

NOTES
1 Absolute maximum ratings are limiting values applied individually, and beyond
which the serviceability of the circuit may be impaired. Functional operability is not
necessarily implied. Exposure to absolute maximum rating conditions for an
extended period of time may affect device reliability.
2 Typical thermal impedance for “ES” package: θJC, 2.2°C/W; θJA, 24.3°C/W.
TEST LEVEL
I 100% Production Tested.
II 100% Production Tested at 25°C, and sample tested at
specified temperatures. AC testing done on sample basis.
III Sample Tested Only.
IV Parameter is guaranteed by design and characteriza-
tion testing.
V Parameter is a typical value only.
VI 100% production tested at temperature at 25°C: sample
tested at temperature extremes.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD13465 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
