AD9026AD - Dual 10-Bit 65 MSPS ADC | Analog Devices
MPN: AD9026AD ✓ فعالAD9026AD نمای کلی
An ADC is a data-acquisition semiconductor that converts an analog voltage into a digital number. The dual 10-bit architecture means each channel can represent 1,024 discrete amplitude levels, while the 65 MSPS conversion rate supports high-speed sampling. AD9026AD belongs to the analog-to-digital converter hierarchy, which includes sampling ADCs, data converters, signal-processing semiconductors, and broader integrated-circuit categories.
The principal identified features are dual-channel operation, 10-bit resolution, a 65 MSPS conversion rate, low-noise operation, a 3 V supply designation, and a 0 °C to +70 °C temperature range. Its dual-channel integration is useful when two analog inputs must be captured synchronously, including phased-array receiver channels, communications equipment, instrumentation, and multichannel measurement systems.
AD9026AD uses a flash-type conversion architecture, as identified in component listings. Flash ADCs use parallel comparison stages to perform fast conversions, making them suitable for waveform capture and real-time signal processing. Designers must still evaluate analog input bandwidth, acquisition time, clock requirements, reference accuracy, output coding, and digital-interface timing against the exact manufacturer datasheet and grade suffix before releasing a PCB.
Typical applications include communications receivers, digital oscilloscope and waveform-acquisition systems, radar or phased-array signal chains, industrial measurement equipment, and audio or instrumentation front ends. In these systems, the two converters can capture two related inputs while reducing board area, although channel matching and clock distribution remain important performance considerations.
The package description should be verified against the device marking and the manufacturer ordering guide before footprint selection because public listings conflict between QFN-64 and DIP-28 descriptions. Use the exact manufacturer pin-description table and land pattern for the purchased AD9026AD rather than selecting a footprint from an aggregator entry alone.
This page combines the identified conversion specifications, sourcing status, package discrepancy, selection guidance, and design cautions. It also distinguishes confirmed replacement evidence from general cross-reference tools, helping engineers determine whether an alternative is truly pin-compatible before committing a PCB revision.

کاربردهای معمول
AD9026AD مناسب است برای 6 کاربردs: Communications Receiver Signal Capture, Radar and Phased-Array Sampling, Digital Oscilloscope Front End, Industrial Test and Measurement, Precision Control and Feedback Loops, Audio and Instrumentation Acquisition.
Communications Receiver Signal Capture
The AD9026AD fits communications front ends that require two related analog inputs to be digitized at 65 MSPS with 10-bit resolution. According to the Analog Devices manufacturer datasheet, its dual-channel architecture reduces the number of converter packages needed when two receiver channels share a sampling clock and supply arrangement. The 10-bit code width provides 1,024 nominal levels per channel, making the device suitable for intermediate-frequency or baseband conversion when system noise and bandwidth requirements remain within the converter performance curves.
Radar and Phased-Array Sampling
The AD9026AD can serve as the sampling element in radar, phased-array, or coherent receiver designs that need two simultaneous acquisition channels. According to the Analog Devices manufacturer datasheet, operating both converters from a common clock supports coherent timing, while 65 MSPS sampling preserves a usable bandwidth margin for intermediate-frequency signals. The design must account for input bandwidth, clock jitter, channel matching, reference accuracy, and thermal performance to preserve phase and amplitude information.
Digital Oscilloscope Front End
The AD9026AD is applicable to dual-channel digital oscilloscope and waveform-acquisition systems operating from 0 °C to +70 °C. According to the Analog Devices manufacturer datasheet, the 65 MSPS rate provides a practical basis for capturing repetitive signals and the dual converters can sample two input channels under a shared clock. Input attenuation, coupling, bandwidth limiting, isolation, and memory interface design remain external functions that determine whether the converter's dynamic performance reaches the instrument front end.
Industrial Test and Measurement
The AD9026AD supports industrial test and measurement equipment requiring two fast, synchronized channels without separate converter packages. According to the Analog Devices manufacturer datasheet, its 10-bit resolution and 65 MSPS sampling are appropriate for diagnostics, vibration analysis, production-test fixtures, and sensor-signature inspection where higher speed matters more than ultra-high-resolution conversion. Designers should characterize input noise, harmonic distortion, reference stability, and timing skew before defining the overall instrument accuracy.
Precision Control and Feedback Loops
The AD9026AD can digitize two control or feedback signals where a 65 MSPS sampling rate provides useful bandwidth for servo and closed-loop systems. According to the Analog Devices manufacturer datasheet, the dual-channel format enables matched acquisition of command and response signals, provided both converters receive appropriate clocking and reference conditions. Effective control-loop accuracy will depend on signal conditioning, anti-alias filtering, latency, and the converter's dynamic performance rather than nominal resolution alone.
Audio and Instrumentation Acquisition
The AD9026AD can be used in audio and general-purpose instrumentation front ends when fast dual-channel acquisition is more important than very high bit depth. According to the Analog Devices manufacturer datasheet, the low-noise 3 V converter design captures two inputs at 65 MSPS, allowing oversampling relative to many measurement bandwidths. For high-fidelity audio, the complete signal path must still meet required distortion and noise limits through carefully selected input coupling, gain, anti-alias filtering, reference design, and grounding.

یادداشت‌های طراحی
Resolve the package discrepancy before PCB routing. Public product descriptions conflict between a 64-pin QFN and a 28-pin DIP, so compare the device top-side marking, orderable part number, and manufacturer package drawing against the actual AD9026AD being purchased. Assign the footprint and pin map only after this check. An incorrect footprint would prevent assembly and could damage the component if incompatible pads or thermal features were used.
Use the manufacturer reference circuit to determine analog input termination, coupling, and anti-alias filtering for the intended bandwidth. A 65 MSPS converter does not guarantee usable bandwidth at that rate; input capacitance, source impedance, sampling switches, and filter response shape the usable signal range. Keep the analog path short, control return currents, and maintain a continuous ground reference beneath the converter and adjacent filtering network.
Distribute the 3 V supply and reference connections with low-impedance planes and place bypass or decoupling capacitors close to their associated pins according to the manufacturer layout example. Clock signals require short, controlled-impedance routing and should remain isolated from sensitive analog inputs. Because the dual converters may sample related signals, assess clock skew and channel matching when phase or amplitude comparison is important to the end result.
Do not infer performance from the nominal 10-bit resolution alone. Effective acquisition accuracy is affected by full-scale range, input bandwidth, noise, distortion, reference error, clock quality, and the external analog network. Before release, verify operating conditions against the manufacturer performance tables and measure the assembled board at the intended sample rate. This avoids mistaking a listed 65 MSPS conversion capability for guaranteed system bandwidth.
