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

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).
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 65 MSPS.
2. Input signal conditioning included; gain and impedance matching.
3. Single-ended, differential, or off-module filter options.
4. Fully tested/characterized full channel performance
5. Pin compatible with 12-bit AD13280 product family.

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.
11
Channel-to-channel isolation tested with A Channel grounded and a full-scale signal applied to B Channel.
12
Digital output logic levels: DVCC = 3.3 V, C
13
Supply voltage recommended operating range. AVCC may be varied from 4.85 V to 5.25 V. However, rated ac (harmonics) performance is valid only over the range AVCC = 5.0 V to 5.25 V.

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.
