Product details
Overview
AD10465/PCB from Analog Devices is a dual-channel, 14-bit, 65 MSPS analog-to-digital converter module with integrated analog input signal conditioning, ±0.5% channel-to-channel gain matching, >90 dB channel isolation, and selectable bipolar input ranges (±0.5 V, ±1.0 V, ±2.0 V). It delivers 70 dB SNR at 5 MHz and 80 dB spurious-free dynamic range for high-fidelity digitization in phased array receivers and GPS antijamming systems.
For engineers reviewing the AD10465/PCB datasheet, AD10465/PCB pinout, AD10465/PCB application, or AD10465/PCB equivalent, this page provides verified technical context, real-world performance boundaries, package-validated pin functions, and confirmed alternative options for multichannel RF receiver designs requiring matched dual-channel acquisition with on-module DC-coupled signal conditioning.
Technical Context
The AD10465/PCB implements two independent AD6644 14-bit ADC cores, each driven by an AD8037 low-distortion amplifier and AD8138 single-to-differential converter, enabling full DC-coupled operation with <0.2 dB gain flatness up to 25 MHz. Its three-pipeline architecture achieves 65 MSPS conversion with aperture uncertainty of 0.3 ps rms and 250 ps channel-to-channel aperture delay matching.
Each channel features laser-trimmed thin-film resistor networks for gain/offset matching, separate ±5.0 V analog supplies (AVCC/AVEE), 3.3 V digital output supply (DVCC), and independent encode inputs (ENCODEA/ENCODEB) supporting asynchronous sampling. Input impedance is configurable per channel (100 Ω/200 Ω/400 Ω) via AINA1–AINA3 and AINB1–AINB3 pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees monotonicity and no missing codes across full industrial temperature range (−40°C to +85°C). |
| Sample Rate | 65 MSPS maximum - supports Nyquist-limited bandwidth up to 32.5 MHz with validated SNR ≥67 dBFS at 32.1 MHz input. |
| Channel Matching | ±0.5% gain error - enables coherent beamforming in phased array receivers without external calibration. |
| Isolation | >90 dB - prevents crosstalk between channels during simultaneous wideband signal acquisition. |
| Input Range | Selectable ±0.5 V / ±1.0 V / ±2.0 V - eliminates need for external programmable gain amplifiers in multimode receivers. |
| Power Dissipation | 3.5 W total (1.75 W per channel) - requires thermal management in compact military-grade enclosures. |
| Spurious-Free Dynamic Range | 85 dBFS at 4.98 MHz - ensures detection of weak signals adjacent to strong interferers in secure communications. |
Pinout & Package
The AD10465/PCB is housed in a 68-lead ceramic leaded chip carrier (CLCC) package, footprint-compatible with AD10242 and AD10265, with internal shield (Pin 1) separating analog sections of Channel A and B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AINA1–AINA3 / AINB1–AINB3 | Analog input selection terminals | Configure input voltage range and impedance per channel (e.g., AINA1 = ±0.5 V, 100 Ω; AINA2 = ±1.0 V, 200 Ω). |
| ENCODEA / ENCODEA / ENCODEB / ENCODEB | Differential encode clock inputs | Accept ac-coupled differential clocks; require <0.3 ps rms jitter for full 14-bit SNR performance. |
| D0A–D13A / D0B–D13B | CMOS-compatible digital outputs | 14-bit twos-complement parallel data (D0 = LSB, D13 = MSB); DVCC = 3.3 V or 5 V selectable. |
| REF_A / REF_B | Internal voltage reference outputs | Provide stable 2.4 V reference for AD8138 common-mode bias; must be decoupled locally. |
| AGNDA / AGNDB / DGNDA / DGNDB | Analog/digital ground returns | Separate ground planes required; AGND and DGND must connect at single point near device. |
Key Features
| Feature | Design Value |
|---|---|
| On-module signal conditioning | Integrates AD8037 amplifier + AD8138 differential driver per channel, eliminating discrete front-end design effort and layout sensitivity. |
| Laser-trimmed resistor matching | Ensures <±0.5% gain error and <±1% offset error over temperature, critical for calibrated I/Q sampling in FLIR processing. |
| Independent channel operation | Supports asynchronous encode timing and analog inputs, enabling time-interleaved or staggered sampling in multichannel receivers. |
| Footprint compatibility | 68-lead CLCC layout matches AD10242/AD10265, allowing drop-in upgrade from 12-bit to 14-bit resolution in existing military PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD6644ASVZ-65 | Single-channel, 14-bit, 65 MSPS; no integrated signal conditioning or channel matching network. | Requires external amplifiers, resistors, and layout tuning to achieve AD10465/PCB's channel match and isolation. | Choose when board space allows discrete front-end design and calibration resources are available. |
| AD9680BCPZ-500 | Dual-channel, 14-bit, 500 MSPS; JESD204B serial output; no analog input conditioning; higher power (3.8 W/ch). | Targets wideband radar/EW; lacks DC coupling and user-selectable input ranges of AD10465/PCB. | Choose for >100 MHz instantaneous bandwidth needs where serial interface and higher sample rate outweigh analog flexibility. |
Compared with AD6644ASVZ-65 and AD9680BCPZ-500, the AD10465/PCB uniquely combines factory-matched dual-channel performance, on-board DC-coupled signal conditioning, and user-configurable input ranges in a military-qualified CLCC package-reducing design cycle time by eliminating front-end characterization and calibration.

FAQ
What is the maximum analog input frequency supported by the AD10465/PCB?
The AD10465/PCB has a full-power analog bandwidth of 100 MHz, meaning it maintains specified SNR and SFDR performance up to 100 MHz input frequency. However, AC specifications such as 70 dB SNR and 85 dBFS SFDR are guaranteed only up to 32.1 MHz per the datasheet's tested conditions at 65 MSPS encode rate. For optimal dynamic performance, keep input frequencies ≤32 MHz.
Does the AD10465/PCB require external reference components?
No, the AD10465/PCB does not require external reference components. It integrates internal voltage references (REF_A and REF_B) derived from the AD6644 cores and buffered by AD8031 op-amps. These 2.4 V references are internally connected to the AD8138 common-mode inputs and must be decoupled with 0.1 µF capacitors close to the REF pins per the evaluation board layout.
Can the AD10465/PCB operate with a single-ended encode clock?
No, the AD10465/PCB requires a differential encode clock applied to complementary ENCODE/ENCODE pairs for each channel. The datasheet explicitly states all AC specifications are tested with differential drive, and single-ended operation degrades aperture jitter and SNR. Use an RF transformer or low-jitter differential oscillator (e.g., MC100LVEL16) to generate the required differential signal.
What is the purpose of the SHIELD pin (Pin 1) on the AD10465/PCB?
The SHIELD pin (Pin 1) is an internal ground shield physically separating Channel A and Channel B analog sections within the 68-lead CLCC package. It must be connected to the system analog ground plane at a single point near the device to maintain >90 dB channel-to-channel isolation and prevent coupling through shared substrate or package parasitics.
How does the AD10465/PCB handle input overvoltage conditions?
The AD10465/PCB provides defined overvoltage recovery: after a 2× full-scale transient, it recovers to 0.02% accuracy within 40–100 ns; after a 4× full-scale transient, recovery takes 150–200 ns. This behavior is enabled by internal clamping and fast-reset track-and-hold circuitry, ensuring minimal disruption to continuous sampling in hostile RF environments.
