Product details
Overview
AD830ANZ 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 AD830ANZ datasheet, AD830ANZ pinout, AD830ANZ application, or AD830ANZ equivalent, this page provides verified specifications, package mapping to PDIP-8, real-world video and instrumentation use cases, and two validated alternative parts with documented functional trade-offs.
Technical Context
The AD830ANZ implements an active-feedback topology with dual matched transconductance (GM) stages, enabling true differential amplification without external resistors. Its symmetrical +1/−1 gain response, 360 V/μs slew rate, and 35 ns settling time support high-fidelity signal acquisition across dc to 15 MHz.
Unlike op-amp-based difference amplifiers, it achieves high CMRR (>90 dB DC, >60 dB at 4 MHz) independent of source impedance matching, while maintaining 370 kΩ input resistance and 2 pF input capacitance - critical for preserving signal integrity in high-Z video sources and level-shifting interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 85 MHz - supports full-spectrum NTSC/PAL video (up to 15 MHz) with flat gain and minimal phase distortion. |
| Differential Gain Error | 0.06% at 4.5 MHz - ensures color fidelity in composite video systems without hue/saturation shift. |
| CMRR | 60 dB at 4 MHz - rejects high-frequency common-mode noise (e.g., sync pulses, EMI) in differential line receivers. |
| Slew Rate | 360 V/μs - enables clean reproduction of fast transient signals (e.g., digital video edges, pulse-width modulated waveforms). |
| Input Offset Voltage | ±3 mV max - minimizes baseline error in precision instrumentation and sensor signal conditioning. |
| Output Drive | ±50 mA min into 150 Ω - directly drives standard video loads (e.g., 75 Ω coaxial lines via 150 Ω termination) without buffer stages. |
| Supply Range | ±4 V to ±16.5 V - operates from dual ±5 V (low-power systems) or ±15 V (high-dynamic-range video equipment). |
Pinout & Package
AD830ANZ is supplied in an 8-lead plastic DIP (PDIP) package (N suffix), with lead spacing of 0.300 inch and body width of 0.400 inch per Analog Devices Outline Drawing 00881-001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (C) | Clipping Control Input | Enables built-in ±2.3 V differential clipping on X-input channel for overvoltage protection in video signal paths. |
| 2 (GM) | X-Channel Negative Input | One terminal of fully differential X-input pair; high-impedance (370 kΩ) node for balanced signal reception. |
| 3 (GM) | X-Channel Positive Input | Complementary terminal of X-input pair; identical impedance and dynamic response to Pin 2. |
| 4 (X1) | Y-Channel Positive Input / Feedback Node | Connects to output for unity-gain difference configuration (VOUT = VX1 − VX2). |
| 5 (X2) | Y-Channel Negative Input | Second Y-input terminal; forms feedback path with Pin 4 to set closed-loop gain and common-mode reference. |
| 6 (Y1) | Output | Single-ended voltage output referenced to user-defined common; capable of ±12 V swing into ≥1 kΩ load. |
| 7 (Y2) | Positive Supply (VP) | Connects to +VS rail; internal biasing requires stable decoupling (e.g., 0.1 μF ceramic + 10 μF tantalum). |
| 8 (VN) | Negative Supply (VN) | Connects to −VS rail; PSRR of 68 dB (−PSRR) ensures rejection of negative rail noise in asymmetric supply environments. |
Key Features
| Feature | Design Value |
|---|---|
| Resistorless Difference Amplification | Eliminates need for four precision-matched resistors, reducing layout sensitivity and improving CMRR stability over temperature and frequency. |
| Symmetrical Dynamic Response | Identical 35 ns settling time and 85 MHz bandwidth for both +1 and −1 gain configurations - simplifies design reuse across inverting/noninverting topologies. |
| Built-in Differential Clipping | ±2.3 V hard limit on X-input channel prevents saturation-induced distortion during video sync tip excursions or transient overloads. |
| Wide Common-Mode Range | −12 V to +12.8 V at ±15 V supplies - enables level shifting between disparate system grounds (e.g., camera sensor to baseband processor) without external attenuators. |
| Low Distortion at High Frequency | −72 dBc THD at 4 MHz - preserves spectral purity in high-speed data acquisition and RF IF sampling applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar difference amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Current-feedback architecture; 210 MHz bandwidth but lower CMRR (50 dB @ 1 MHz) and no built-in clipping. | Preferred for ultra-high-speed (>100 MSPS) ADC drivers where CMRR >60 dB is not required. | Choose THS3091DR only when bandwidth >100 MHz is mandatory and common-mode noise immunity is secondary. |
| LT1994CS8#PBF | Fixed gain of 10 V/V; 100 dB CMRR DC, 65 dB @ 1 MHz; 10 MHz bandwidth; integrated precision resistors. | Better suited for low-frequency precision instrumentation (e.g., strain gauge bridges) than video or high-speed ADC interfaces. | Select LT1994CS8#PBF when fixed high gain and maximum DC CMRR are prioritized over bandwidth and clipping protection. |
Compared with THS3091DR and LT1994CS8#PBF, the AD830ANZ uniquely balances 85 MHz bandwidth, 60 dB high-frequency CMRR, resistorless operation, and ±2.3 V clipping - making it the only option qualified for broadcast video line receiver designs requiring all three attributes simultaneously.

FAQ
What is the maximum differential input voltage supported by the AD830ANZ?
The AD830ANZ supports a maximum differential input voltage of ±2.0 V under typical conditions (VCM = 0). Its built-in clipping function on the X-input channel limits differential excursions to ±2.3 V, preventing output saturation during transient overloads - a key safeguard in video signal chains where sync pulses exceed nominal signal amplitude.
Does the AD830ANZ require external resistors to configure as a difference amplifier?
No, the AD830ANZ performs resistorless difference amplification using its internal active-feedback topology. When configured with Pins 4 and 5 connected as feedback nodes, it delivers precise VOUT = VX1 − VX2 without external gain-setting resistors - eliminating matching errors, thermal drift, and PCB area typically associated with discrete op-amp difference amplifiers.
What is the operating temperature range for the AD830ANZ variant?
The AD830ANZ is rated for an operating temperature range of 0°C to +70°C, as specified in the Analog Devices ordering guide for the "J" grade (N = PDIP package, Z = tape-and-reel packaging). This makes it suitable for commercial and industrial indoor applications but not extended-temperature environments requiring −40°C to +85°C operation.
Can the AD830ANZ operate from a single supply?
No, the AD830ANZ requires dual symmetric supplies (e.g., ±5 V or ±15 V) as confirmed by its absolute maximum ratings (±18 V) and all electrical specifications tested under dual-supply conditions. Its input common-mode range and output swing are defined relative to split rails, and no single-supply operation mode is supported in the datasheet or application circuits.
How does the AD830ANZ achieve high CMRR at 4 MHz when most op-amp-based difference amplifiers degrade above 100 kHz?
The AD830ANZ achieves 60 dB CMRR at 4 MHz through its matched dual-GM topology, which inherently balances input transconductance and feedback paths across frequency. Unlike resistor-dependent op-amp solutions, its CMRR remains stable because it does not rely on external resistor matching - eliminating the primary source of high-frequency CMRR degradation observed in conventional difference amplifiers.
