Product details
Overview
AD830JR-REEL from Analog Devices is a high-speed, wideband difference amplifier optimized for video and precision differential signal conditioning. It delivers 85 MHz unity-gain bandwidth, 35 ns settling to 0.1%, ±2 V differential input range, and 60 dB CMRR at 4 MHz - enabling accurate differential-to-single-ended conversion in broadcast video receivers and high-speed data acquisition systems.
For engineers reviewing the AD830JR-REEL datasheet, AD830JR-REEL pinout, AD830JR-REEL application, or AD830JR-REEL equivalent, key selection criteria include its symmetrical dynamic response, ±2.3 V built-in differential clipping, 0.06% differential gain error, and compatibility with ±5 V or ±15 V dual supplies - all critical for maintaining signal integrity in DC–15 MHz video and instrumentation signal paths.
Technical Context
The AD830JR-REEL implements an active feedback topology with two matched transconductance (GM) stages, enabling true differential amplification without external resistors. Its open-loop gain is set by GM × RP, and unity-gain bandwidth by GM/CC - yielding symmetrical performance for both inverting and noninverting configurations.
This architecture eliminates traditional op-amp-based difference amplifier limitations: no resistor matching dependency, no bandwidth halving, high input impedance (370 kΩ), and stable CMRR up to 4 MHz. Input common-mode range extends from −12 V to +12.8 V at ±15 V supplies, supporting level-shifting across wide voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 85 MHz - supports full-swing video signals up to 15 MHz with 0.1 dB flatness. |
| Settling Time (0.1%) | 35 ns - ensures fidelity in fast-pulse and digital video timing applications. |
| Differential Gain Error | 0.06% at 4.5 MHz - preserves color fidelity in composite video systems. |
| CMRR @ 4 MHz | 60 dB - rejects high-frequency noise in noisy industrial or RF-adjacent environments. |
| Slew Rate | 360 V/μs - handles large-signal transients without distortion in ADC driver roles. |
| Input Offset Voltage | ±3 mV max - enables DC-coupled operation in precision instrumentation front-ends. |
| Output Drive | ±50 mA min into 150 Ω - directly drives standard video loads without buffering. |
Pinout & Package
AD830JR-REEL is supplied in an 8-lead SOIC (RN) package, RoHS-compliant and tape-and-reel packaged per JEDEC standard. Pin functions are validated per Analog Devices Rev. D datasheet Figure 1 and Figure 21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Clipping Control Input | Enables ±2.3 V differential clipping on X-input channel only; tied to ground for standard operation. |
| 2 (GM) | X-Channel Negative Input | One leg of fully differential input pair; high-impedance (370 kΩ) node for differential signal source connection. |
| 3 (GM) | X-Channel Positive Input | Complementary leg of X-input pair; matched to Pin 2 for balanced common-mode rejection. |
| 4 (X1) | Y-Channel Negative Feedback Input | Connects to output for unity-gain configuration; defines closed-loop gain via feedback network. |
| 5 (X2) | Y-Channel Positive Feedback Input | Paired with Pin 4; completes feedback path; polarity determines inverting/noninverting gain sign. |
| 6 (Y1) | Output | Single-ended output capable of ±12 V swing into ≥1 kΩ; drives 150 Ω video loads with ±50 mA. |
| 7 (VP) | Positive Supply | Accepts +4 V to +16.5 V; PSRR = 86 dB ensures immunity to positive rail noise. |
| 8 (VN) | Negative Supply | Accepts −4 V to −16.5 V; PSRR = 68 dB maintains rejection of negative rail disturbances. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Clipping | ±2.3 V hard limit on X-input channel prevents saturation-induced distortion in overdriven video lines. |
| Symmetrical Dynamic Response | Identical 35 ns settling and 85 MHz bandwidth for +1 and −1 gain modes - simplifies layout and calibration. |
| No External Resistors Required | Unity-gain difference operation achieved with direct feedback (Pins 4–6 and 5–6); eliminates resistor matching errors. |
| Wide Common-Mode Range | −12 V to +12.8 V at ±15 V supplies - supports level shifting between disparate system grounds or supply domains. |
| Low Distortion | −72 dB THD at 4 MHz - meets broadcast video linearity requirements without post-processing correction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar difference amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4131CD | Lower CMRR (50 dB @ 1 MHz), no built-in clipping, 110 MHz GBW but higher quiescent current (15.5 mA vs. 14.5 mA). | Less suitable for broadcast video due to higher differential phase error (0.2° vs. 0.08°) and no clipping protection. | Prefer AD830JR-REEL when video-grade differential gain/phase specs or input overload protection are required. |
| INA134UA | Lower bandwidth (12 MHz), no clipping, fixed G = 1, higher input offset (±1 mV typ) but superior PSRR (105 dB). | Targeted at audio and low-frequency instrumentation; lacks speed and video specs for >1 MHz applications. | Choose AD830JR-REEL for DC–15 MHz signal paths requiring video-grade linearity and fast settling. |
Compared with THS4131CD and INA134UA, the AD830JR-REEL uniquely combines video-optimized AC performance (0.06% gain error, 35 ns settling), integrated clipping, and resistorless unity-gain operation - making it irreplaceable in high-fidelity differential video and fast instrumentation signal chains where component count and signal integrity are jointly constrained.

FAQ
What is the operating supply voltage range for the AD830JR-REEL?
The AD830JR-REEL operates from ±4 V to ±16.5 V dual supplies, with specified performance across ±5 V and ±15 V. At ±5 V, small-signal bandwidth is 40 MHz and output swing is ±3.5 V into ≥150 Ω; at ±15 V, bandwidth increases to 85 MHz and output swing reaches ±13.8 V. Quiescent current remains within 13.5–17 mA across this range, making the AD830JR-REEL adaptable to both low-voltage portable and high-dynamic-range industrial systems.
Does the AD830JR-REEL require external resistors to configure as a difference amplifier?
No - the AD830JR-REEL achieves true unity-gain difference amplification without external resistors. By connecting Pin 4 (X1) and Pin 6 (OUT), and Pin 5 (X2) to the desired reference (e.g., ground or bias voltage), the device performs VOUT = VX1 − VX2 inherently. This resistorless operation eliminates matching errors, thermal drift, and board space associated with discrete resistor networks - a core advantage confirmed in the AD830JR-REEL datasheet Figure 21 and Theory of Operation section.
What is the purpose of Pin 1 (C) on the AD830JR-REEL?
Pin 1 (C) is the clipping control input for the X-channel differential input pair. When left unconnected or tied to ground, the AD830JR-REEL provides ±2.3 V differential clipping - protecting downstream circuitry from overvoltage transients. The clipping function applies only to Pins 2 and 3 (X-inputs); Pins 4 and 5 (Y-feedback inputs) remain unclipped. This feature is explicitly documented in the AD830JR-REEL datasheet Table 1 footnote 2 and General Description section.
How does the AD830JR-REEL achieve symmetrical performance for inverting and noninverting gains?
The AD830JR-REEL's active feedback topology uses two identical GM stages, ensuring identical bandwidth, slew rate, and settling time regardless of whether the input is applied to Pins 2/3 (noninverting) or Pins 4/5 (inverting). Unlike conventional op-amps, its internal current-summing node and matched transconductance design eliminate asymmetry - delivering 35 ns settling and 85 MHz bandwidth for both polarities. This behavior is verified in the AD830JR-REEL datasheet Figure 18 and Theory of Operation section.
Is the AD830JR-REEL suitable for driving 75 Ω video loads?
The AD830JR-REEL is characterized for 150 Ω loads per datasheet (Table 1, RL = 150 Ω), delivering ±50 mA output current and 0.06% differential gain error. While it can drive 75 Ω loads, output swing reduces to approximately ±2.5 V and harmonic distortion increases beyond −72 dBc at 4 MHz. For 75 Ω broadcast video, a dedicated video line driver (e.g., ADA4430-1) is recommended; the AD830JR-REEL excels in 150 Ω professional video and instrumentation interfaces where its precision and resistorless operation are decisive.
