AD9226ASTZRL - 12-Bit 65 MSPS ADC | Analog Devices
MPN： AD9226ASTZRL ✓ 啟用中AD9226ASTZRL 概覽
An ADC converts an analog voltage into a digital numeric representation. The AD9226 belongs to the pipeline ADC category, where multistage internal converters operate with a latency between sampling and output availability. Its 12-bit resolution provides 4,096 digital codes, while the 65 MSPS sampling rate supports acquisition of rapidly changing signals. The integrated sample-and-hold amplifier captures the input during the sampling interval, and the internal voltage reference helps reduce the need for external reference circuitry.
Key verified features include 12-bit resolution, 65 MSPS throughput, one analog input, a differential pipeline architecture, a parallel data interface, and a 48-LQFP package. The manufacturer describes the device as a monolithic, single-supply ADC fabricated on an advanced CMOS process. The sample-and-hold amplifier is specifically suited to IF undersampling schemes, including single-channel communication applications where input frequencies can reach or exceed the Nyquist frequency.
The AD9226 is appropriate for communications receivers, RF and IF signal-chain conversion, radar-related instrumentation, industrial measurement systems, and digital signal-processing front ends. Because the converter uses a parallel output, the surrounding system must provide compatible digital voltage levels, sufficient data capture timing, clocking, grounding, and decoupling. The 48-LQFP footprint is suitable for conventional surface-mount assembly but requires careful attention to analog signal integrity and clock jitter.
A key design consideration is ensuring that the analog input, reference, and clock paths have appropriate impedance and return paths. The datasheet should be consulted for the exact pinout, input range, output coding, timing, supply requirements, and recommended application circuit because those details are not fully available in the supplied distributor excerpts. The verified data identifies the industrial package and temperature grade, but it does not provide enough information to fabricate all electrical parameters.
This page combines verified manufacturer and distributor information with package, application, selection, and design guidance. It is intended to help engineers identify the AD9226ASTZRL for high-speed conversion while clearly separating confirmed specifications from parameters that require confirmation in the official datasheet.

典型應用
AD9226ASTZRL 適用於 6 應用s: Communications Receiver Front End, RF and IF Signal-Chain Conversion, Digital Oscilloscope and Instrumentation, Industrial Control and Monitoring, Radar and Pulse-Signal Capture, High-Speed Data Acquisition.
Communications Receiver Front End
The AD9226ASTZRL fits high-speed communications receiver designs that require converting an analog IF or other analog waveform into 12-bit digital data. Its verified 65 MSPS sampling rate and differential pipeline architecture are appropriate for wideband receiver front ends, while the integrated sample-and-hold amplifier supports IF undersampling schemes described by Analog Devices. The parallel interface makes the device suitable for systems that capture each conversion with an FPGA, ASIC, or high-speed digital receiver. Designers should confirm the exact input range, output timing, supply rails, and permissible clock jitter in the AD9226 datasheet.
推薦
RF and IF Signal-Chain Conversion
AD9226ASTZRL is a strong candidate for RF and IF measurement paths where the analog signal must be sampled rapidly and converted into digital data for subsequent demodulation, filtering, or analysis. Analog Devices specifically identifies IF undersampling as an application for the AD9226 sample-and-hold amplifier. The 12-bit resolution provides a practical balance between conversion speed and signal detail, while the 48-LQFP package supports compact surface-mount construction. The receiver designer must establish gain, anti-alias filtering, reference integrity, and clock quality before treating converter performance as usable system performance.
推薦
Digital Oscilloscope and Instrumentation
The AD9226ASTZRL can serve as the ADC in a high-speed digital acquisition instrument when the system requires 65 million samples per second and 12-bit numerical resolution. Its single-channel input and parallel output are useful for feeding a capture buffer, FPGA pipeline, or display-processing engine. The industrial temperature range of -40°C to +85°C supports equipment designed for controlled industrial environments. Practical implementation requires careful analog grounding, controlled clocking, matched input impedance, and a capture architecture that accommodates the converter’s pipeline latency and parallel-output timing.
推薦
Industrial Control and Monitoring
AD9226ASTZRL is applicable to industrial monitoring systems that digitize fast-changing analog quantities for analysis, thresholding, vibration monitoring, or process diagnostics. The 12-bit resolution gives each sample a 4,096-code representation, and the 65 MSPS throughput provides temporal resolution for transients. Its specified -40°C to +85°C industrial temperature range makes it suitable for equipment operating across controlled industrial environments. The analog input path should include conditioning and protection appropriate to the measured signal, while digital outputs require controlled impedance, timing margin, and proper power sequencing.
推薦
Radar and Pulse-Signal Capture
The AD9226ASTZRL may be used in radar, pulse, and transient-signal capture systems where a 65 MSPS sampling rate is sufficient for the target bandwidth and 12-bit resolution preserves useful amplitude detail. Its sample-and-hold amplifier and IF undersampling capability can simplify some analog signal-chain arrangements. A practical radar receiver still requires front-end gain control, filtering, mixer or detector selection, clock synchronization, and a real-time data path. Because the supplied excerpts do not provide input sensitivity, SFDR, SNR, or aperture-jitter figures, system designers should obtain those parameters from the official datasheet before making a sensitivity or dynamic-range decision.
推薦
High-Speed Data Acquisition
AD9226ASTZRL is appropriate for compact high-speed data-acquisition modules that convert an analog waveform into parallel digital words. The 65 MSPS rate can capture short time windows, transient events, or modulated signals, while the 12-bit format maps naturally into common FPGA and DSP processing paths. The 48-LQFP 7 mm × 7 mm package allows a moderate-density layout, but 48-pin routing still demands careful escape routing and controlled return paths. System designers should model propagation delay, output timing, clock skew, and connector/cable losses to ensure that the complete acquisition channel preserves the required bandwidth.

主要差異化特點
- 65 MSPS sampling rate (對比AD9238BSTZ-40)
- Integrated sample-and-hold amplifier and voltage reference (對比AD9226ASTZ)
- Single-channel differential pipeline architecture (對比AD9226ASTRL)
設計說明
Treat the analog input, clock, and reference paths as controlled-impedance RF-like signal paths even though the device is an ADC. Keep the input trace short, minimize discontinuity between the source and AD9226ASTZRL, and return the reference and analog grounds through a quiet path. The 65 MSPS sampling rate makes clock jitter and input-edge timing significant even when the numeric output is only 12 bits.
Place input, reference, and decoupling components close to their associated pins, with the shortest practical connections to the 48-LQFP package. Follow the manufacturer’s recommended layout and pin definitions rather than inferring connections from the distributor excerpts. Provide adequate via access for the LQFP thermal and electrical requirements, and route the parallel digital outputs away from sensitive analog and clock traces.
Confirm the exact supply voltage, current, sequencing, and decoupling requirements from the official AD9226 datasheet before layout release. The verified data confirms single-supply operation but does not provide numerical supply limits or current consumption. Power filtering should prevent switching supplies or digital output activity from coupling into the sample-and-hold amplifier, reference, and input network.
Do not treat a same-family or similar-resolution ADC as a drop-in replacement without checking pin names, output coding, clock polarity, timing, supply levels, and package geometry. The supplied cross-reference results do not establish full equivalence for the alternatives. Also confirm the output latency and data-valid timing in the receiver FPGA or DSP; the verified excerpts describe the pipeline architecture but do not provide complete timing tables.
合規資訊
The supplied search results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for AD9226ASTZRL. These values must be verified from the current Analog Devices product documentation or authorized distributor records before procurement.
