Product details
Overview
AD9215BRU-65 from Analog Devices is a monolithic, single-supply 10-bit analog-to-digital converter (ADC) with 65 MSPS sampling rate, 300 MHz analog input bandwidth, and integrated sample-and-hold amplifier and voltage reference. It operates from a 2.7 V to 3.3 V analog supply and delivers 58 dBc SNR at Nyquist, supporting IF sampling in communications receivers and ultrasound front-ends.
For engineers reviewing the AD9215BRU-65 datasheet, AD9215BRU-65 pinout, AD9215BRU-65 application, or AD9215BRU-65 equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, and two confirmed alternative parts for signal chain migration paths.
Technical Context
The AD9215BRU-65 implements a multistage differential pipelined ADC architecture with on-chip error correction logic, enabling guaranteed no-missing-codes performance across −40°C to +85°C. Its patented differential SHA supports both ac- and dc-coupled inputs with user-selectable 1 Vp-p or 2 Vp-p full-scale ranges.
A dedicated clock duty cycle stabilizer maintains SNR/SFDR performance over wide input clock duty cycle variation (e.g., 30%–70%), while separate AVDD (3 V) and DRVDD (2.5 V) supplies isolate analog and digital domains. The OR (out-of-range) output flag signals overflow conditions independent of MSB polarity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees 1024 discrete output codes with guaranteed no missing codes over full temperature range. |
| Max Sampling Rate | 65 MSPS - defines maximum sustained data throughput; latency fixed at 5 clock cycles regardless of rate. |
| SNR @ Nyquist | 58 dBc - sets minimum detectable signal floor above noise for baseband or IF digitization up to 32.5 MHz. |
| Analog Bandwidth | 300 MHz - enables accurate sampling of RF/IF signals up to ~100 MHz without external anti-alias filtering. |
| Power @ 65 MSPS | 96 mW (AVDD) + 18 mW (DRVDD) - total 114 mW; enables battery-powered instrumentation with thermal headroom. |
| Differential Nonlinearity | ±0.25 LSB (typ) - ensures monotonic transfer function critical for closed-loop control and precision measurement. |
| Input Voltage Range | 1 Vp-p or 2 Vp-p differential - selectable via REFT/REFB pins; simplifies interface to mixers, amplifiers, or transformers. |
Pinout & Package
AD9215BRU-65 is housed in a 28-lead TSSOP (RU-28) package with exposed pad not present; thermal resistance θJA = 67.7°C/W. All pins are surface-mount compatible and require standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input | Accepts 300 MHz bandwidth signal; supports ac/dc coupling and single-ended configuration via common-mode bias. |
| CLK | Asynchronous sampling clock input | Rising-edge triggered; internal duty cycle stabilizer tolerates 30%–70% pulse width without SNR degradation. |
| D0–D9 | Parallel CMOS digital outputs | 10-bit straight binary or twos complement; driven by separate DRVDD (2.5 V) for mixed-voltage system interfacing. |
| OR | Out-of-range indicator | Active-high flag signaling input overload beyond ±FSR/2; used with MSB to distinguish high/low saturation. |
| MODE | Data format & DCS enable control | Logic level selects offset binary/twos complement and enables/disables clock duty cycle stabilizer. |
| SENSE, VREF, REFT, REFB | Reference configuration terminals | Configure internal 1.0 V or 0.5 V reference; support external reference injection or differential reference termination. |
| PDWN | Power-down control | Active-high signal reduces power to 1.0 mW standby; wake-up time ≤7 ms with recommended decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3 V analog supply | Eliminates dual-rail design complexity; AVDD (2.7–3.3 V) powers analog core and reference, reducing BOM count. |
| On-chip reference & SHA | Removes need for external reference IC and op-amp buffer; enables compact layout in space-constrained medical or portable gear. |
| Flexible input range selection | 1 Vp-p or 2 Vp-p differential span configurable via SENSE pin; matches output swing of common RF mixers and VGA stages. |
| Separate digital driver supply | DRVDD (2.25–3.6 V) allows direct interface to 2.5 V or 3.3 V logic without level shifters in FPGA or ASIC data capture paths. |
| 5-cycle pipeline latency | Predictable, fixed delay simplifies timing closure in real-time DSP systems; enables deterministic synchronization with DACs or FPGAs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9226ARZ-65 | 12-bit resolution, same 65 MSPS rate, higher 75 mW power, no integrated reference. | Higher dynamic range required for spectral analysis; external reference needed for calibration stability. | Choose when ENOB >9.5 bits is mandatory and board area permits external reference circuitry. |
| ADS5271IPFP | Texas Instruments 10-bit, 65 MSPS, 1.8 V digital I/O, lower 65 mW total power, no DCS. | Lower voltage logic interface required; reduced jitter sensitivity but less robust to clock asymmetry. | Prefer for ultra-low-power portable designs where clock source has stable 50% duty cycle. |
Compared with AD9215BRU-65, AD9226ARZ-65 trades power and integration for 2-bit resolution gain, while ADS5271IPFP reduces power and logic voltage at the cost of clock flexibility and reference integration-making AD9215BRU-65 optimal for mixed-signal systems needing self-contained, robust IF digitization.

FAQ
What is the maximum analog input frequency supported by AD9215BRU-65?
The AD9215BRU-65 features a 300 MHz analog input bandwidth, allowing accurate digitization of signals up to ~100 MHz without significant amplitude roll-off. This supports undersampling of IF signals in communications and high-frequency echo returns in ultrasound, provided the Nyquist criterion is met for the selected sampling rate of 65 MSPS.
Does AD9215BRU-65 require an external voltage reference?
No, AD9215BRU-65 integrates a precision 1.0 V (or 0.5 V) voltage reference and supports internal reference operation by default. External reference can be applied via the VREF pin if tighter drift or custom scaling is required, but it is not necessary for standard operation.
How does the clock duty cycle stabilizer in AD9215BRU-65 improve system robustness?
The clock duty cycle stabilizer in AD9215BRU-65 actively corrects sampling aperture timing errors caused by non-50% clock duty cycles, maintaining 58 dBc SNR even with 30%–70% pulse width variation. This eliminates the need for external clock conditioning circuits in systems using crystal oscillators or PLLs with asymmetric outputs.
What is the purpose of the OR (out-of-range) output on AD9215BRU-65?
The OR output on AD9215BRU-65 is an active-high flag indicating analog input has exceeded the selected full-scale range (±0.5 V or ±1.0 V). Used alongside the MSB, it distinguishes high-side saturation from low-side saturation-enabling real-time signal clipping detection and automatic gain control in adaptive receivers.
Can AD9215BRU-65 operate with a 2.5 V digital supply?
Yes, AD9215BRU-65 accepts DRVDD from 2.25 V to 3.6 V, making 2.5 V fully supported. Its digital outputs are designed for 2.5 V CMOS logic levels (VOH ≥2.45 V, VOL ≤0.05 V), enabling direct connection to FPGAs or ASICs without level-shifting circuitry.
