Product details
Overview
AD847JRZ-REEL7 from Analog Devices is a high-speed, low-power monolithic operational amplifier optimized for video, imaging, and high-speed data acquisition systems. It delivers 50 MHz unity-gain bandwidth, 300 V/µs slew rate, and 0.04% differential gain (NTSC/PAL) at ±15 V supply, enabling precision analog signal conditioning in flash ADC buffers and cable drivers.
For engineers reviewing the AD847JRZ-REEL7 datasheet, AD847JRZ-REEL7 pinout, AD847JRZ-REEL7 application, or AD847JRZ-REEL7 equivalent, this page provides verified specifications, SOIC-8 package details, real-world settling time (65 ns to 0.1%), video-grade distortion performance, and validated alternative options for high-speed op amp selection.
Technical Context
The AD847JRZ-REEL7 uses Analog Devices' complementary bipolar (CB) process with npn input stage and fast pnp folded cascode gain stage, enabling stable unity-gain operation without external compensation. Its internal compensation capacitor (CF) dynamically adapts to capacitive loads, maintaining stability while driving up to 1000 pF.
It features rail-to-rail input common-mode range (±14.3 V at ±15 V supplies), 15 nV/√Hz input voltage noise at 10 kHz, and 1.5 pA/√Hz input current noise - balancing speed, precision, and low-noise integrity for demanding analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 50 MHz at ±15 V - supports full-power signal reproduction up to 12.7 MHz (5 Vp-p) for flash ADC buffering. |
| Slew Rate | 300 V/µs at ±15 V - enables clean 10 V step response with 65 ns settling to 0.1% error. |
| Differential Gain / Phase | 0.04% / 0.19° at 4.4 MHz - meets broadcast video fidelity requirements for NTSC and PAL systems. |
| Input Offset Voltage | 0.5 mV (typ) - minimizes DC error in precision gain stages and sensor interfaces. |
| Quiescent Current | 5.3 mA at ±15 V - achieves high-speed performance with low power overhead for dense PCB layouts. |
| Output Voltage Swing | ±10 V into 500 Ω at ±15 V - drives standard video line loads and active filter stages without clipping. |
| Common-Mode Rejection | 78 dB min (±12 V CM input) - ensures robust rejection of supply- and layout-induced interference. |
Pinout & Package
AD847JRZ-REEL7 is supplied in an 8-lead Small Outline Integrated Circuit (SOIC) package (R-8), RoHS-compliant, tape-and-reel format (EIA-481A). Package dimensions: 4.90 mm × 3.91 mm × 1.75 mm, with 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to external potentiometer for fine-tuning input offset voltage; unused in default configuration. |
| 2 | Inverting Input (–IN) | High-impedance differential input node; requires matched impedance (e.g., RB = 1 kΩ) to minimize bias current error. |
| 3 | Noninverting Input (+IN) | High-impedance differential input node; protected by ±6 V differential limit; requires series resistor under overload conditions. |
| 4 | –VS | Negative supply rail connection; must be bypassed with 0.1 µF ceramic capacitor near pin. |
| 5 | Offset Null | Second terminal of offset nulling network; used with Pin 1 for manual calibration. |
| 6 | Output | Low-output-impedance (15 Ω open-loop) driver capable of sourcing/sinking 32 mA; stable into any capacitive load. |
| 7 | +VS | Positive supply rail connection; must be bypassed with 0.1 µF ceramic capacitor near pin. |
| 8 | NC | No internal connection; left unconnected per datasheet - not used for thermal or electrical functions. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable with no external compensation | Internally compensated CB architecture eliminates need for external feedback capacitor in most configurations. |
| Capacitive load drive capability | Stable operation driving ≥1000 pF loads - enables direct interface to coaxial cables, ADC input capacitance, and long PCB traces. |
| Video-optimized AC performance | 0.04% differential gain + 0.19° differential phase at 4.4 MHz - certified for broadcast-quality video signal paths. |
| Wide supply range support | Operates from ±4.5 V to ±18 V - compatible with legacy ±5 V and modern ±15 V industrial and test equipment rails. |
| Low input bias current | 3.3 µA typical - reduces voltage error across high-value feedback networks (e.g., >10 kΩ) in precision gain stages. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD827ARZ | Dual-channel version with identical per-amplifier specs (50 MHz BW, 300 V/µs); higher quiescent current (6.3 mA per amp). | Preferred where space-constrained designs require two matched high-speed amps (e.g., in-amp front-end or differential driver). | Select AD827ARZ when dual-channel integration reduces component count and inter-channel matching is critical. |
| LM6361M/NOPB | Lower unity-gain bandwidth (45 MHz), higher input bias current (10 µA), no guaranteed video specs (differential gain/phase not characterized). | Suitable for general-purpose high-speed amplification but not validated for broadcast video or precision ADC buffering. | Choose LM6361M/NOPB only for cost-sensitive non-video applications where 0.04% differential gain is not required. |
Compared with AD847JRZ-REEL7, AD827ARZ offers channel pairing at minor power cost, while LM6361M/NOPB trades video fidelity and precision for lower unit cost - making AD847JRZ-REEL7 the optimal choice for time-critical, distortion-sensitive signal chains.

FAQ
What is the maximum capacitive load the AD847JRZ-REEL7 can drive while remaining stable?
The AD847JRZ-REEL7 is internally compensated to remain stable when driving any capacitive load, including up to 1000 pF as verified in Figure 24 of the official datasheet. Its adaptive CF compensation network ensures phase margin remains ≥50° even under heavy capacitive loading, eliminating need for external isolation resistors in most video and DAC buffer configurations.
Does the AD847JRZ-REEL7 support single-supply operation?
The AD847JRZ-REEL7 is specified for dual-supply operation (±4.5 V to ±18 V) and does not support true single-supply operation. Its input common-mode range extends to within 1.7 V of each rail (e.g., –13.4 V to +14.3 V at ±15 V), but it lacks rail-to-rail input or output capability and requires symmetric supplies for specified AC/DC performance.
What is the purpose of Pins 1 and 5 on the AD847JRZ-REEL7?
Pins 1 and 5 are offset null terminals used together with an external 10 kΩ potentiometer to adjust input offset voltage. As stated in the "OFFSET NULLING" section (Rev. F, p.9), this circuit reduces residual DC error below 0.5 mV - critical in precision integrators or low-gain instrumentation amplifiers where offset drift impacts long-term accuracy.
Is the AD847JRZ-REEL7 pin-compatible with the LM6361?
Yes - the AD847JRZ-REEL7 and LM6361 share identical SOIC-8 (R-8) pinout and footprint, including power, input, output, and offset null connections. However, LM6361 lacks guaranteed video specifications and exhibits higher input bias current, so functional replacement requires validation of differential gain/phase and settling behavior in the target application.
What is the recommended power supply bypassing scheme for the AD847JRZ-REEL7?
Analog Devices specifies 0.1 µF ceramic disc capacitors placed as close as possible to Pins 4 (–VS) and 7 (+VS), directly between each supply rail and analog ground. Additional bulk capacitance (e.g., 10 µF tantalum) may be added at the board level, but the 0.1 µF local bypass is mandatory to suppress high-frequency supply noise and maintain 50 MHz bandwidth integrity.
