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
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 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.
