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

AD13465
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, including 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 conditioning, 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, allowing 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’ MIL38534 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 complementary bipolar process (XFCB).

NOTES
1
Gain tests are performed on AMP-IN-X-1 input voltage range.
2
Input capacitance spec. combines AD8037 capacitance and ceramic package capacitance.
3
Full Power Bandwidth is the frequency at which the spectral power of the fundamental frequency (as determined by FFT analysis) is reduced by 3 dB.
4
For differential input: +IN = 1 V p-p and –IN = 1 V p-p (signals are 180° out of phase). For single ended input: +IN = 2 V p-p and –IN = GND.
5
All AC specifications tested by driving ENCODE and ENCODE differentially. AMP-IN-X-1 = 1 V p-p, AMP-IN-X-2 = GND.
6
Minimum and Maximum conversion rates allow for variation in Encode Duty Cycle of 50% ± 5%.
7
Analog Input signal power at –1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to total noise (first five harmonics removed).
Encode = 65 MSPS. SNR is reported in dBFS, related back to converter full scale.
8
Analog Input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics.
Encode = 65 MSPS. SINAD is reported in dBFS, related back to converter full scale.
9
Analog Input signal power at –1 dBFS; SFDR is ratio of converter full scale to worst spur.
10
Both input tones at –7 dBFS; two tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third order intermod product.

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.
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.
