For engineers reviewing the AD876JR-REEL datasheet, AD876JR-REEL pinout, AD876JR-REEL application, or AD876JR-REEL equivalent, this page delivers verified technical context, real-world timing and accuracy specs, SOIC-28 package mapping, and validated alternative options for video-speed ADC selection.
Technical Context
The AD876JR-REEL implements a multistage pipelined architecture with output error correction logic to achieve 10-bit accuracy at 20 MSPS while maintaining guaranteed no missing codes across 0°C to +70°C. Its internal sample-and-hold amplifier supports differential nonlinearity of ±0.5 LSB and full-power bandwidth of 150 MHz.
It features force-sense reference inputs (REFTF/REFTS/REFBF/REFBS) to minimize voltage drop errors, three-state digital outputs compatible with +3.3 V or +5 V logic, and a standby mode reducing power below 50 mW. The pipeline latency is 3.5 clock cycles with aperture jitter of 22 ps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size of ~1.95 mV for 2 Vp-p input range. |
| Sampling Rate | 20 MSPS - supports real-time digitization of baseband video signals up to ~10 MHz Nyquist frequency. |
| Power Dissipation | 160 mW at 20 MSPS - enables thermal management in dense PCB layouts without forced cooling. |
| Differential Nonlinearity | ±0.5 LSB - ensures monotonic transfer function and eliminates code ambiguity in closed-loop control. |
| Input Range | 2 Vp-p - matches standard video signal swing and simplifies interface with op-amp drivers like AD817. |
| Reference Interface | Force-sense (REFTF/REFTS/REFBF/REFBS) - compensates for PCB trace resistance to maintain <0.1% gain error. |
| Aperture Jitter | 22 ps - limits SNR degradation to ≤56 dB at 1 MHz input, critical for high-fidelity signal capture. |
Pinout & Package
AD876JR-REEL is packaged in a 28-lead SOIC (R-28) with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint. Thermal pad not present; body dimensions 17.9 × 7.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D9 | Digital output (LSB to MSB) | Straight binary coding; three-state controlled by THREE-STATE pin; interfaces directly to FPGA or ASIC data bus. |
| THREE-STATE | Digital input | Active-low control: pulls outputs to high-Z when HIGH, enabling shared bus operation without external buffers. |
| STBY | Digital input | Active-high entry into standby mode; reduces power to <50 mW for intermittent acquisition duty cycles. |
| CLK | Digital input | Single-ended CMOS clock; accepts +3.3 V or +5 V logic; internal buffer referenced to DRVDD; 50 ns period minimum. |
| AIN | Analog input | Differential-capable single-ended node; requires drive source capable of settling 5 pF within 25 ns for 10-bit accuracy. |
| REFTF / REFBF | Analog input (force) | Supply terminals for reference ladder; nominal 4.0 V / 2.0 V; must deliver ~8 mA total current. |
| REFTS / REFBS | Analog input (sense) | High-impedance Kelvin connections; must remain unconnected if force-sense not used to avoid reference error. |
| AVDD / AVSS | Analog power | +5 V analog supply and ground; must be decoupled locally with 0.1 µF ceramic + 10 µF tantalum per supply pin. |
| DVDD / DVSS | Digital power | +5 V digital core supply and ground; separate from analog ground to prevent noise coupling into conversion path. |
| DRVDD / DRVSS | I/O power | +3.3 V or +5 V supply for digital I/O buffers; sets CLK input threshold at DRVDD/2; enables mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Pipelined multistage architecture | Enables 20 MSPS throughput with only ~100 comparators vs. 1023 in flash ADCs-reducing die area and dynamic power. |
| Guaranteed no missing codes | Validated over full commercial temperature range (0°C to +70°C); eliminates data gaps in real-time streaming applications. |
| Adjustable reference input | Supports REFT/REFB settings from 1.6 V/3.5 V to 2.5 V/4.5 V-enabling flexible input span tuning for varying sensor outputs. |
| Three-state digital outputs | Allows direct connection to multiplexed data buses without external bus transceivers-reducing BOM count and layout complexity. |
| Standby power-down mode | Reduces current draw to <10 mA total-extending battery life in portable CCD scanners and electronic still cameras. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9203ARUZ | 10-bit, 40 MSPS, 3 V supply only, LVDS outputs, no force-sense reference | Better speed and lower voltage, but requires level-shifting for +5 V systems and lacks reference Kelvin sensing | Select when migrating to 3.3 V/1.8 V systems and higher throughput is required; verify layout compatibility with LVDS routing. |
| MAX1186EEE+ | 10-bit, 20 MSPS, +3.3 V supply, internal reference, no standby mode, 24-pin QSOP | Lower power (110 mW), integrated reference simplifies design, but lacks flexibility in reference scaling and power-down control | Prefer for cost-sensitive, space-constrained designs where fixed 2 Vp-p input and no standby are acceptable trade-offs. |
Compared with AD876JR-REEL, AD9203ARUZ offers double the sampling rate but demands full redesign for LVDS interface and 3 V operation, while MAX1186EEE+ reduces component count via internal reference yet sacrifices reference adjustability and standby functionality critical for portable imaging.

FAQ
What is the operating temperature range for the AD876JR-REEL?
The AD876JR-REEL is specified for the commercial temperature range of 0°C to +70°C. This rating applies to all electrical specifications including INL (±1.0 LSB), DNL (±0.5 LSB), and dynamic performance (SINAD ≥49 dB at 1 MHz). Operation outside this range may result in unguaranteed timing margins or increased missing-code risk.
Does the AD876JR-REEL support differential analog input?
The AD876JR-REEL accepts single-ended analog input on the AIN pin and does not include a dedicated differential input pair. However, its internal sample-and-hold structure and common-mode rejection enable robust operation with externally generated pseudo-differential signals, provided the common-mode voltage remains within the 1.6 V to 4.5 V reference window defined by REFBF and REFTF.
Can the AD876JR-REEL operate with a 3.3 V digital supply on DRVDD?
Yes, the AD876JR-REEL supports DRVDD = +3.3 V, which sets the CLK input threshold to ~1.65 V and configures digital I/Os for +3.3 V logic compatibility. DVDD and AVDD must remain at +5 V. This configuration allows seamless interfacing with 3.3 V FPGAs while preserving analog performance and reference stability.
How is the reference configured for optimal accuracy in the AD876JR-REEL?
For optimal accuracy, use force-sense reference connections: drive REFTF and REFBF with stable +4.0 V and +2.0 V sources, then connect REFTS and REFBS directly to those same nodes-without routing current through sense lines. This configuration nulls out voltage drops across internal 5 Ω resistors and maintains <0.1% gain error across temperature.
What is the purpose of the CML pin on the AD876JR-REEL?
The CML pin on the AD876JR-REEL is an analog output providing bypass access to an internal bias point. It must be decoupled to AVSS with a 0.1 µF ceramic capacitor to stabilize internal analog circuitry. Leaving CML floating or connecting it to other nets degrades noise performance and may cause conversion instability.
