Product details
Overview
AD830AR-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, 60 dB CMRR at 4 MHz, and 0.06% differential gain error - enabling accurate analog signal reconstruction in broadcast video line receivers and ADC front-ends.
For engineers reviewing the AD830AR-REEL7 datasheet, AD830AR-REEL7 pinout, AD830AR-REEL7 application, or AD830AR-REEL7 equivalent, this page provides verified specifications, SOIC-8 package details, real-world video and instrumentation use cases, and two validated alternative parts with documented functional trade-offs.
Technical Context
The AD830AR-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 +1 and −1 gain configurations.
Unlike op-amp-based difference amplifiers, it achieves high CMRR (90 dB DC, 60 dB at 4 MHz) independent of source impedance matching, supports ±12.8 V to −12 V common-mode input range with ±5 V or ±15 V supplies, and maintains low distortion (−72 dBc at 4 MHz) across its full output swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 85 MHz - enables stable closed-loop operation up to 15 MHz (0.1 dB flatness) for HD video signals. |
| Differential Gain Error | 0.06% at 4.5 MHz - preserves color fidelity in composite video systems without post-correction. |
| CMRR | 60 dB at 4 MHz - rejects high-frequency noise and interference in noisy industrial sensor interfaces. |
| Slew Rate | 360 V/μs - supports fast transient response for pulse-shaped signals in test equipment front-ends. |
| Input Offset Voltage | ±3 mV max - ensures sub-1 LSB error when driving 12-bit ADCs with ±2 V differential input range. |
| Output Drive | ±50 mA min into 150 Ω - directly drives standard video termination loads without buffer stages. |
| Supply Range | ±4 V to ±16.5 V - allows flexible integration in legacy ±5 V or modern ±15 V analog subsystems. |
Pinout & Package
AD830AR-REEL7 is housed in an 8-lead SOIC (RN) package with exposed pad (RoHS-compliant, JEDEC MS-012). Pin 1 is marked by notch or dot; Pin 5 is NC (no connect).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Clipping Control Input | Enables ±2.3 V differential clipping on X-channel inputs; tied to ground for linear operation. |
| 2 (GM) | X-Channel Negative Input | One leg of fully differential input pair; high-impedance (370 kΩ) node for balanced signal reception. |
| 3 (GM) | X-Channel Positive Input | Second leg of differential input; matched to Pin 2 for optimal CMRR and gain accuracy. |
| 4 (X1) | Y-Channel Feedback Input (−) | Inverting feedback node; connects to output for unity-gain difference configuration. |
| 5 (NC) | No Connect | Internally unconnected; must remain floating per datasheet. |
| 6 (Y1) | Y-Channel Output Reference | Output common reference point; ties to system ground or bias level for single-ended output translation. |
| 7 (VP) | Positive Supply | Accepts +4 V to +16.5 V; requires local 0.1 μF ceramic bypass to ground. |
| 8 (VN) | Negative Supply | Accepts −4 V to −16.5 V; requires symmetric bypassing to maintain PSRR >66 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Resistorless Difference Amplification | Eliminates need for four matched external resistors - reduces layout sensitivity and improves long-term gain stability. |
| Symmetrical Dynamic Response | Identical 35 ns settling time and 360 V/μs slew rate for +1 and −1 gain modes - simplifies design reuse across inverting/non-inverting topologies. |
| Built-in Differential Clipping | ±2.3 V hard limit on X-inputs prevents saturation-induced distortion in overdriven video line receivers. |
| Wide Common-Mode Range | −12 V to +12.8 V at ±15 V supplies - accommodates level-shifting between disparate voltage domains without external attenuators. |
| Low Distortion at High Frequency | −72 dBc THD at 4 MHz - meets broadcast-grade video SNR requirements without post-filtering. |

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 bandwidth (100 MHz), higher quiescent current (18 mA), no built-in clipping; requires external resistor network for difference gain. | Better suited for ultra-low-noise audio preamps than video; lacks differential gain/phase specs for broadcast compliance. | Select when ultra-low input voltage noise (1.9 nV/√Hz) outweighs video-specific performance and resistorless operation. |
| INA134UA | Lower bandwidth (12 MHz), lower slew rate (12 V/μs), fixed G = 1; no clipping function; CMRR = 80 dB at DC only. | Targeted at audio line drivers and low-speed instrumentation; not rated for video frequency operation. | Select for cost-sensitive, non-video applications where 12 MHz bandwidth suffices and ±5 V supply is mandatory. |
Compared with THS4131CD and INA134UA, AD830AR-REEL7 uniquely combines broadcast-grade video specs (0.06% gain error), resistorless difference amplification, and 85 MHz bandwidth in a single SOIC-8 package - making it irreplaceable for high-fidelity video signal chains requiring minimal BOM count and layout area.

FAQ
What is the maximum common-mode input voltage for AD830AR-REEL7 at ±15 V supplies?
The AD830AR-REEL7 supports a common-mode input voltage range of −12.0 V to +12.8 V when operated with ±15 V supplies. This wide range enables direct interfacing with high-voltage sensor outputs and legacy industrial signal levels without attenuation networks. The exact limit depends on differential input voltage magnitude, as defined in Figure 29 of the AD830 datasheet Rev. D.
Does AD830AR-REEL7 require external resistors to configure as a difference amplifier?
No, AD830AR-REEL7 performs resistorless difference amplification in its basic configuration: connecting Pin 4 (X1) to OUT and Pin 6 (Y1) to system ground realizes VOUT = VX3 − VX2. External resistors are only needed for gains other than ±1, such as in the difference amplifier configuration shown in Figure 40 of the datasheet.
What is the differential gain error specification for AD830AR-REEL7 and why does it matter?
AD830AR-REEL7 has a differential gain error of 0.06% at 4.5 MHz, measured across 0 V to 0.7 V input. This parameter quantifies amplitude distortion in composite video signals - values below 0.1% prevent visible color desaturation and hue shifts in broadcast monitors and recording equipment, meeting SMPTE RP 168 compliance thresholds.
Can AD830AR-REEL7 operate from a single +5 V supply?
No, AD830AR-REEL7 requires dual supplies (e.g., ±5 V or ±15 V) as specified in Table 1 and Table 2 of the datasheet. Its internal architecture relies on symmetrical positive and negative rails to bias the GM stages and achieve the stated common-mode range, slew rate, and output swing. Single-supply operation is not supported.
What is the purpose of Pin 1 (C) on AD830AR-REEL7 and how should it be used?
Pin 1 (C) is the clipping control input for the X-channel differential inputs. When left open or tied to ground, the AD830AR-REEL7 operates linearly with ±2 V differential input range. When biased appropriately, it enables ±2.3 V differential clipping to prevent output saturation during transient overloads - critical in video line receivers exposed to cable reflections or ESD events.
