Product details
Overview
AD830JR-REEL7 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, ±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-REEL7 datasheet, AD830JR-REEL7 pinout, AD830JR-REEL7 application, or AD830JR-REEL7 equivalent, this page provides verified specifications, SOIC-8 package details, real-world video and level-shifting use cases, and two validated alternative parts with documented functional trade-offs.
Technical Context
The AD830JR-REEL7 implements an active feedback topology with dual matched transconductance (GM) stages, enabling true differential amplification without external resistors. Its symmetrical dynamic response ensures identical 35 ns settling time and 360 V/μs slew rate for both inverting and noninverting gain configurations.
Unlike op-amp-based difference amplifiers, it achieves high CMRR (90 dB DC, 60 dB at 4 MHz) without precision resistor matching and maintains 0.06% differential gain error and 0.08° phase error at 4.5 MHz - critical for NTSC/PAL video fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 85 MHz - supports full-spectrum video signals up to 15 MHz (0.1 dB flatness) with minimal group delay distortion. |
| Differential Gain/Phase Error | 0.06% / 0.08° at 4.5 MHz - meets broadcast-grade video linearity requirements without post-correction circuitry. |
| CMRR | 60 dB @ 4 MHz - rejects high-frequency common-mode noise (e.g., EMI on twisted-pair video lines) while preserving signal integrity. |
| Slew Rate | 360 V/μs - enables clean reproduction of fast transient video sync pulses and digital waveform edges. |
| Input Common-Mode Range | −12 V to +12.8 V (±15 V supplies) - accommodates wide-swing industrial sensor outputs and legacy video signal levels. |
| Output Drive | ±50 mA min into 150 Ω - directly drives standard 75 Ω video loads with 1 V rms output and <0.1% distortion. |
| Supply Range | ±4 V to ±16.5 V - operates from dual ±5 V logic supplies or ±15 V analog rails without level-shifting circuitry. |
Pinout & Package
AD830JR-REEL7 is housed in an 8-lead SOIC (RN) package, RoHS-compliant, tape-and-reel format (REEL7 = 1000-piece reel). Pin 1 marked with dot; pins 3 and 6 are no-connect (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Clipping Level Control | Adjusts differential clipping threshold (±2.3 V); tied to ground for default operation. |
| 2 (GM) | Inverting Input (X2) | One leg of fully differential input pair; high-impedance (370 kΩ), low-capacitance (2 pF) node. |
| 3 (GM) | No Connect | Internally unused; must remain unconnected per datasheet. |
| 4 (X1) | Noninverting Input (X1) | Second leg of differential input; matches Pin 2 in impedance and noise performance. |
| 5 (VP) | Positive Supply | +VS rail connection; requires local 0.1 μF ceramic bypass to ground. |
| 6 (OUT) | Output | Single-ended voltage output referenced to VN; capable of ±50 mA drive into 150 Ω. |
| 7 (VN) | Negative Supply | −VS rail connection; separate ground return path improves PSRR (68 dB to VN). |
| 8 (Y1/Y2) | Feedback Input | Internal Y-GM stage inputs; configured as unity-gain buffer when OUT connected to Y2. |
Key Features
| Feature | Design Value |
|---|---|
| Resistorless Gain = 1 Configuration | Eliminates external resistor matching errors and thermal drift, ensuring stable 0.1% gain accuracy over temperature. |
| Wide Common-Mode Input Range | Supports level-shifting applications where input signals exceed supply rails (e.g., ±10 V sensor outputs into ±5 V system). |
| Low Distortion at High Frequency | −72 dBc THD at 4 MHz preserves signal fidelity in ADC front-ends and RF IF chain buffers. |
| Matched Dynamic Response | Identical 35 ns settling time for +1 and −1 gain modes simplifies design of polarity-switchable instrumentation paths. |
| Built-in Differential Clipping | Hardware-limited ±2.3 V input prevents saturation-induced recovery delays in video clamping circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar difference amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DR | Higher 1.8 GHz bandwidth but lower 45 dB CMRR at 10 MHz; requires external gain-setting resistors. | Better suited for RF IF amplification than video; lacks built-in clipping and DC-coupled CMRR optimization. | Select THS3201DR only when >500 MHz small-signal bandwidth is required and CMRR >55 dB above 1 MHz is not critical. |
| LT1994CS8#PBF | Fixed G = 10 configuration; 70 MHz bandwidth; 80 dB DC CMRR but degrades to 45 dB at 1 MHz. | Optimized for current-sense amplification; limited common-mode range (±2.5 V on ±5 V supplies). | Choose LT1994CS8#PBF for high-side current sensing with integrated gain, not for wide common-mode video or level-shifting. |
Compared with THS3201DR and LT1994CS8#PBF, AD830JR-REEL7 uniquely balances video-grade linearity (0.06%/0.08°), wide common-mode range (−12 V to +12.8 V), and resistorless unity-gain operation - making it irreplaceable in broadcast infrastructure and precision analog signal routing.

FAQ
What is the maximum differential input voltage supported by the AD830JR-REEL7?
The AD830JR-REEL7 supports a maximum differential input voltage of ±2.0 V under typical conditions, with built-in clipping limiting at ±2.3 V on Pins 1 and 2. This range ensures linear operation for standard video signals (0–0.7 V) and industrial sensor outputs without external attenuation, and is explicitly specified in Table 1 of the Rev. D datasheet for both ±5 V and ±15 V supplies.
Does the AD830JR-REEL7 require external resistors to configure unity gain?
No, the AD830JR-REEL7 achieves true unity-gain difference amplification without external resistors. Its internal active feedback topology uses matched GM stages to enforce VOUT = VX1 − VX2 when the output is connected to Pin 8 (Y2), as shown in Figure 21(a) of the datasheet. This eliminates resistor matching errors and thermal drift that degrade gain accuracy in discrete op-amp solutions.
Can the AD830JR-REEL7 operate from a single +5 V supply?
No, the AD830JR-REEL7 requires dual-supply operation (±4 V to ±16.5 V) and does not support single-supply configurations. Its input common-mode range and output swing are defined relative to symmetric positive and negative rails; attempting single-supply use violates absolute maximum ratings and results in undefined behavior or damage, as confirmed by Table 3 (Absolute Maximum Ratings) and Figure 29 (common-mode vs. differential voltage curves).
What is the guaranteed settling time specification for the AD830JR-REEL7?
The AD830JR-REEL7 guarantees 35 ns settling time to 0.1% for a 4 V output step under ±15 V supplies and 150 Ω load, per Table 1 (Dynamic Characteristics). At ±5 V supplies, the settling time is 48 ns for the same step, as specified in Table 2. These values are measured with 4.7 pF load capacitance and reflect actual performance in video pulse and sync signal applications.
Is the AD830JR-REEL7 pin-compatible with other members of the AD830 family?
Yes, the AD830JR-REEL7 shares identical pinout and footprint with all AD830 variants (e.g., AD830JN, AD830ARZ) in SOIC-8 (RN) packaging. Pin functions - including NC on Pins 3 and 6, differential inputs on Pins 2/4, and feedback on Pin 8 - are consistent across the family, enabling direct substitution in existing designs without PCB modification.
