Product details
Overview
AD830JR 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 time 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 datasheet, AD830JR pinout, AD830JR application, or AD830JR equivalent, this page provides verified specifications, validated pin functions, confirmed video-grade performance metrics (0.06% differential gain error, 0.08° phase error), and real-world design context for level-shifting, ADC driver, and line-receiver use cases.
Technical Context
The AD830JR implements an active feedback topology with dual matched transconductance (GM) stages, enabling true differential amplification without external resistors. Its symmetrical dynamic response ensures identical 85 MHz bandwidth and 360 V/μs slew rate for both inverting and noninverting gain configurations.
Unlike op-amp-based difference amplifiers, the AD830JR 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 ±50 mA output drive, and maintains low distortion (−72 dB THD @ 4 MHz) across ±4 V to ±16.5 V dual supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 85 MHz - enables full-spectrum video signal amplification up to 15 MHz (0.1 dB flatness) without phase degradation. |
| CMRR @ 4 MHz | 60 dB - rejects high-frequency common-mode noise in noisy industrial or RF-adjacent environments. |
| Differential Gain Error | 0.06% @ 4.5 MHz - preserves color fidelity in composite video systems requiring broadcast-grade accuracy. |
| Settling Time | 35 ns to 0.1% - supports fast-pulse applications like digital imaging sensor readout and high-speed test equipment. |
| Output Drive | ±50 mA min into 150 Ω - directly drives standard video loads (e.g., 75 Ω coax with termination) without buffer stages. |
| Input Offset Voltage | ±3 mV max - ensures dc-coupled precision in instrumentation-grade differential measurement circuits. |
| Slew Rate | 360 V/μs - handles large-amplitude, fast-edge signals (e.g., 4 V step) without slewing-induced distortion. |
Pinout & Package
AD830JR is supplied in an 8-lead plastic DIP (PDIP) package (package code N), with lead spacing of 0.300 inches and body width of 0.355 inches per Analog Devices Standard Military Drawing 5962-9313001MPA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Clipping Control Input | Enables built-in ±2.3 V differential clipping on X-channel inputs; open or grounded for normal operation. |
| 2 (GM) | Inverting Input of X GM Stage | One terminal of fully differential input pair; accepts negative half of differential signal (VX2). |
| 3 (GM) | Noninverting Input of X GM Stage | Other terminal of fully differential input pair; accepts positive half of differential signal (VX1). |
| 4 (X1) | Noninverting Input of Y GM Stage | Feedback node connection point; tied to output for unity-gain configuration (VY1 = VOUT). |
| 5 (X2) | Inverting Input of Y GM Stage | Second feedback node; connected to reference voltage (e.g., ground or bias) to set output common-mode level. |
| 6 (Y1) | Output | Single-ended buffered output delivering VOUT = VX1 − VX2 + VY2, referenced to VY2. |
| 7 (VP) | Positive Supply | Accepts +4 V to +16.5 V; internal circuitry requires ≥2 V headroom from rail for full swing. |
| 8 (VN) | Negative Supply | Accepts −4 V to −16.5 V; supports symmetric (±15 V) or asymmetric (±5 V) supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Differential Clipping Level | ±2.3 V on X-inputs only - prevents overdrive distortion in video sync pulse handling without external clamps. |
| Supply Flexibility | Operates from ±4 V to ±16.5 V - allows direct integration into legacy ±5 V logic systems or high-dynamic-range ±15 V analog backplanes. |
| DC-Coupled Common-Mode Range | −12 V to +12.8 V at ±15 V supplies - enables level shifting between disparate system grounds (e.g., isolated sensor front-end to ADC). |
| Resistorless Gain = 1 | No external resistors required for unity gain - eliminates resistor mismatch errors and saves PCB area in space-constrained designs. |
| Video-Optimized Linearity | 0.06% differential gain / 0.08° phase error - meets SMPTE RP-168 and ITU-R BT.601 broadcast video standards without calibration. |

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 @ 4 MHz), no built-in clipping, 110 MHz bandwidth but higher quiescent current (15.5 mA vs. 14.5 mA). | Preferred for ultra-high-bandwidth (>100 MHz) RF IF applications; unsuitable for broadcast video due to 0.25% differential gain error. | Select THS4131CD only when bandwidth >100 MHz is mandatory and video fidelity is not required. |
| INA134UA | Audio-optimized (20 Hz–200 kHz), lower slew rate (12 V/μs), no differential clipping, ±13 V max supply. | Designed for audio line receivers; lacks video bandwidth and differential gain/phase specs needed for composite video. | Choose INA134UA only for low-frequency audio differential signaling where cost and power are primary constraints. |
Compared with THS4131CD and INA134UA, the AD830JR uniquely combines broadcast-grade video linearity (0.06% gain error), integrated differential clipping, and wide common-mode range (−12 V to +12.8 V) - making it irreplaceable in professional video infrastructure where signal integrity is non-negotiable.

FAQ
What is the maximum common-mode input voltage range for AD830JR at ±15 V supplies?
The AD830JR 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 robust interfacing with sensors, transducers, and legacy video sources that generate large common-mode offsets, and is specified under DC conditions with ±10 V differential input per the AD830JR datasheet Rev. D, Table 1.
Does AD830JR require external resistors to configure unity-gain difference amplification?
No, the AD830JR does not require external resistors for unity-gain difference amplification. Its internal active feedback topology allows resistorless configuration: connect Pin 4 (X1) to Pin 6 (OUT), tie Pin 5 (X2) to the desired output reference voltage (e.g., ground), and apply the differential signal across Pins 2 and 3 (GM terminals). This is explicitly shown in Figure 21(a) of the AD830JR datasheet.
What is the differential gain error specification of AD830JR and under what test conditions?
The AD830JR has a differential gain error of 0.06% typical (0.09% max) at 4.5 MHz, measured with 0 V to 0.7 V input amplitude, ±15 V supplies, and RL = 150 Ω load. This specification is guaranteed across the AD830JR's commercial temperature range (0°C to +70°C) and is critical for maintaining color accuracy in NTSC/PAL video systems, as documented in Table 1 of the AD830JR datasheet Rev. D.
Can AD830JR operate from ±5 V supplies, and how does performance change compared to ±15 V?
Yes, the AD830JR is fully specified for ±5 V operation. At ±5 V, its small-signal bandwidth reduces to 40 MHz (vs. 85 MHz at ±15 V), 0.1 dB gain flatness drops to 6.5 MHz (vs. 15 MHz), and output swing is limited to ±3.5 V into 150 Ω. These trade-offs are quantified in Table 2 of the AD830JR datasheet and reflect reduced headroom and slew capability - making ±5 V suitable for portable or low-power video interfaces where full bandwidth is not required.
What is the function of Pin 1 (C) on the AD830JR, and is it required for basic operation?
Pin 1 (C) is the clipping control input for the X-channel differential inputs (Pins 2 and 3). When left open or grounded, the AD830JR operates normally with ±2.3 V differential clipping. Connecting Pin 1 to a voltage above 1.5 V disables clipping. For standard difference amplifier use - including video line reception and ADC driving - Pin 1 is not required and may be left unconnected, as confirmed in the "Connection Diagram" and "Features" sections of the AD830JR datasheet.
