Product details
Overview
AD9071BR-REEL from Analog Devices is a monolithic 10-bit, 100 MSPS analog-to-digital converter with on-chip track-and-hold, 280 MHz analog bandwidth, and single 5 V supply operation. It delivers SINAD = 54 dB at 41 MHz input and supports differential or single-ended analog inputs for digital communications, spectrum analysis, and medical imaging systems.
For engineers reviewing the AD9071BR-REEL datasheet, AD9071BR-REEL pinout, AD9071BR-REEL application, or AD9071BR-REEL equivalent, key selection considerations include its 100 MSPS sampling rate, offset binary output coding, out-of-range (OR) flag, TTL/CMOS-compatible digital outputs, and SOIC-28 package with separate VCC/VDD supplies.
Technical Context
The AD9071BR-REEL employs a two-step subranging architecture with digital error correction, initiating conversion on each rising edge of the ENCODE signal. Its analog input stage features high-speed differential amplification and supports ±512 mV p-p input range referenced to common-mode voltage of –2.5 V ± 0.2 V.
Digital outputs are latched with three-pipeline latency (data N appears after ENCODE edge N+3), and timing parameters include aperture uncertainty of 3.0 ps rms and output valid time of 2.0–4.0 ns. The device integrates an internal 2.5 V reference (VCC – 2.5 V) with 130 ppm/°C tempco and supports external reference via VREF IN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size and dynamic range for digitizing analog signals |
| Sampling Rate | 100 MSPS - maximum sustained conversion throughput for real-time high-frequency signal capture |
| Analog Bandwidth | 280 MHz - usable frequency range before –3 dB roll-off, enabling wideband RF and IF sampling |
| SINAD @ 41 MHz | 53 dB typical - signal integrity metric indicating effective resolution under high-frequency input conditions |
| Power Dissipation | 450 mW at 100 MSPS - total system power budget impact with VCC = 5 V and VDD = 3.3 V |
| Input Range | ±512 mV p-p - full-scale differential input swing compatible with transformer-coupled or op-amp-driven sources |
| Output Coding | Offset binary - simplifies interface with FPGA/ASIC logic by eliminating sign-bit inversion in data path |
| Aperture Uncertainty | 3.0 ps rms - timing jitter contribution directly limiting SNR at high input frequencies |
Pinout & Package
AD9071BR-REEL is housed in a 28-lead wide-body SOIC (R-28) package, specified for industrial temperature range (–40°C to +85°C), with θJA = 71°C/W thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 12, 21, 23 | GND | Ground return for analog and digital sections; requires low-inductance connection to minimize noise coupling |
| 2, 8, 11 | VCC | Analog power supply (5 V); must be bypassed locally with 0.1 µF ceramic capacitor per pin |
| 3 | VREF OUT | Internal 2.5 V reference output; used to drive external circuitry or strap to VREF IN for internal reference mode |
| 4 | VREF IN | Reference input pin; accepts external 2.5 V source for improved accuracy or gain adjustment |
| 5, 6 | DNC | Do not connect; no internal connection - must remain unconnected and unstubbed |
| 9, 10 | AIN / AIN | Differential analog input pair; supports true/complementary configuration with 15 kΩ input resistance and 3 pF capacitance |
| 13 | ENCODE | Sampling clock input; rising-edge triggered, TTL/CMOS compatible, with 4.5–13 ns pulsewidth requirement |
| 14 | OR | Out-of-range flag; asserts HIGH when input exceeds ±512 mV p-p, locking outputs at saturation codes |
| 15–19, 24–28 | D9–D0 | 10-bit parallel digital outputs (D9 MSB); driven at VDD level (3.3 V or 5 V) with 1.4 ns rise time |
| 20, 22 | VDD | Digital output supply; user-selectable 3–5 V range to match interfacing logic family voltage levels |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold | Eliminates need for external T/H amplifier, reducing board area and signal path complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9051BR-REEL | 8-bit, 65 MSPS; lower resolution and speed; 300 mW power | Suitable for cost-sensitive, lower-bandwidth instrumentation where 10-bit resolution is unnecessary | Select when system SNR requirements are ≤48 dB and sampling rate < 70 MSPS |
| ADS5271IPFP | 12-bit, 65 MSPS; higher resolution but slower; 1.8 V/3.3 V dual-supply; serial LVDS output | Better for high-precision, lower-speed applications with space-constrained PCB layouts and noise-sensitive environments | Select when 12-bit accuracy is required and serial interface reduces routing complexity |
Compared with AD9071BR-REEL, AD9051BR-REEL trades resolution and speed for lower cost and power, while ADS5271IPFP offers higher resolution and differential LVDS outputs at reduced sampling rate - neither is pin-compatible, requiring layout and firmware adaptation.

FAQ
What is the absolute maximum analog input voltage for the AD9071BR-REEL?
The AD9071BR-REEL specifies absolute maximum analog input voltage as VCC to 0.0 V (i.e., 0 V to 5 V). However, the functional full-scale range is ±512 mV p-p differential. Exceeding ±512 mV p-p triggers the OR output and saturates digital outputs at 3FFH or 000H. Input voltages beyond 1 V to 5 V may cause invalid codes or damage.
Does the AD9071BR-REEL require external decoupling capacitors, and if so, what values?
Yes, the AD9071BR-REEL requires local 0.1 µF ceramic chip capacitors (0603 size) placed flush against each VCC and VDD pin, as specified in the evaluation board layout and application notes. Additional 10 µF tantalum capacitors are recommended on bulk supply lines. Placing bypass caps on the bottom side degrades performance due to increased parasitic inductance.
Can the AD9071BR-REEL operate with a 3.3 V digital supply only, or does it require both 5 V and 3.3 V?
The AD9071BR-REEL requires both supplies: VCC = 5 V for analog core operation and VDD = 3.3 V (or 5 V) for digital outputs. VCC powers the ADC, T/H, and reference circuits; VDD sets logic-high level for D9–D0 and OR outputs. Operating VCC below 5 V violates specifications and degrades dynamic performance.
What is the meaning of "offset binary" coding in the AD9071BR-REEL, and how does it affect data interpretation?
Offset binary coding maps analog input zero (0 V differential) to code 512 (10 0000 0000), positive full scale (+512 mV p-p) to 1023 (11 1111 1111), and negative full scale (–512 mV p-p) to 0 (00 0000 0000). This eliminates sign-bit inversion needed in two's complement, simplifying FPGA-based data capture and real-time processing in the AD9071BR-REEL.
Is the AD9071BR-REEL RoHS compliant and lead-free?
Yes, the AD9071BR-REEL is RoHS compliant and lead-free, as confirmed by Analog Devices' official product change notices and packaging documentation for the R-28 SOIC package. The "BR" suffix denotes the RoHS-compliant, Pb-free plastic SOIC variant, and "-REEL" indicates tape-and-reel packaging for automated assembly.
