Product details
Overview
OPA2613IDRG4 from Texas Instruments is a dual, wideband, voltage-feedback operational amplifier optimized for xDSL differential line drivers and precision analog signal conditioning. It delivers 1.8nV/√Hz input voltage noise, 230MHz unity-gain bandwidth, ±350mA output current per channel, ±0.2mV input offset voltage, and operates from single +5V to +12V or dual ±2.5V to ±6V supplies - enabling high-fidelity twisted-pair line driving in DSL modems.
For engineers reviewing the OPA2613IDRG4 datasheet, OPA2613IDRG4 pinout, OPA2613IDRG4 application, or OPA2613IDRG4 equivalent, key selection criteria include low-noise differential gain stability, harmonic distortion ≤ −95dBc at 1MHz (RL ≥ 500Ω), rail-swing capability on +5V supply, and SO-8 package compatibility with thermal resistance of 125°C/W.
Technical Context
The OPA2613IDRG4 employs a unity-gain stable voltage-feedback architecture with a dedicated high-current output stage capable of sourcing/sinking ±350mA linearly. Its internal biasing is supply-voltage independent, supporting stable operation across ±2.5V to ±6V or +5V to +12V rails without performance degradation.
It achieves <5MHz bandwidth for 0.1dB gain flatness at G = +2 and maintains ≤2.6dB peaking at unity gain, ensuring predictable frequency response in active filters and ADC driver loops. Differential configurations deliver >14-bit dynamic range through 5MHz with matched channel noise and distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 1.8nV/√Hz at f > 10kHz - enables low-noise PLL integrators and precision baseband I/Q amplifiers |
| Unity-Gain Bandwidth | 230MHz - supports wideband xDSL line driver applications up to ADSL2+ frequencies |
| Output Current | ±350mA per channel - drives heavy twisted-pair loads (e.g., 100Ω differential) without clipping |
| Input Offset Voltage | ±0.2mV max at +25°C - ensures DC accuracy in transimpedance and active filter designs |
| Supply Range | Single +5V to +12V or dual ±2.5V to ±6V - simplifies power architecture in multi-rail systems |
| Quiescent Current | 6.0mA per channel - enables low-power xDSL CPE designs while maintaining wide bandwidth |
| Harmonic Distortion | ≤ −95dBc (2nd/3rd) at 1MHz, 2VPP, RL ≥ 500Ω - meets stringent spectral purity requirements for DSL upstream channels |
Pinout & Package
OPA2613IDRG4 is housed in an SO-8 (D) surface-mount package with standard 1.27mm pitch, JEDEC MS-012AC compliant, and thermal resistance θJA = 125°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+VS) | Positive Supply | Accepts +5V to +12V (single) or +2.5V to +6V (dual); decoupling required near pin |
| 2 (Out B) | Channel B Output | Delivers ±350mA into 100Ω load; swing within 1.0V of either rail on +5V supply |
| 3 (−In B) | Inverting Input B | Differential pair node for channel B; CMIR extends to ±4.7V at ±6V supply |
| 4 (+In B) | Noninverting Input B | High-impedance input (7MΩ || 1pF); used for single-ended or differential feedback networks |
| 5 (Out A) | Channel A Output | Independent output with identical specs to Out B; supports dual-channel I/Q or stereo paths |
| 6 (−In A) | Inverting Input A | Matches −In B electrically; enables matched differential gain configurations |
| 7 (+In A) | Noninverting Input A | Symmetric to +In B; critical for channel-to-channel crosstalk < −80dBc at 1MHz |
| 8 (−VS) | Negative Supply | Accepts 0V (single-supply ground) or −2.5V to −6V; must be decoupled locally |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband, high-output-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2677IDR | Current-feedback architecture; higher slew rate (1800V/µs) but higher input bias current (±1.2µA) | Better for very high-speed pulse applications; less suitable for precision DC-coupled integrators due to bias current | Select OPA2677IDR when >100MHz large-signal bandwidth is prioritized over DC accuracy and low noise |
| OPA2690IDR | Voltage-feedback like OPA2613IDRG4; lower noise (1.6nV/√Hz) but reduced output current (±190mA) | Preferred for ultra-low-noise ADC drivers where load is light (<50mA); insufficient for twisted-pair line driving | Select OPA2690IDR for low-noise, low-distortion applications with moderate output current demands |
Compared with OPA2613IDRG4, OPA2677IDR trades DC precision and low noise for extreme speed via current-feedback topology, while OPA2690IDR improves noise floor by 0.2nV/√Hz but sacrifices 45% peak output current - making OPA2613IDRG4 optimal for balanced wideband line driving with precision.

FAQ
What is the maximum operating supply voltage for OPA2613IDRG4?
The OPA2613IDRG4 supports a maximum operating supply voltage of ±6.5V over −40°C to +85°C, or ±6.65V over 0°C to +70°C. Absolute maximum ratings specify ±6.5V for industrial temperature range; exceeding this risks permanent damage. The device operates reliably across its specified range of single +5V to +12V or dual ±2.5V to ±6V, with tested performance up to ±6V in characterization.
Does OPA2613IDRG4 support single-supply operation at +5V?
Yes, OPA2613IDRG4 fully supports single +5V operation with verified performance: it delivers 2VPP output swing into 100Ω, 21MHz large-signal bandwidth, and ≤ −82dBc 2nd-harmonic distortion at 1MHz. Input common-mode range extends from 1.2V to 3.8V, and output swings from 1.0V to 4.0V (no load), enabling AC-coupled configurations with mid-supply biasing as shown in Figure 3 of the datasheet.
What is the thermal resistance (θJA) of OPA2613IDRG4 in SO-8 package?
The junction-to-ambient thermal resistance (θJA) for OPA2613IDRG4 in the SO-8 (D) package is 125°C/W under standard JEDEC test conditions. This value assumes a 2-layer PCB with no internal copper planes; actual thermal performance improves with enhanced copper pour and thermal vias. Maximum junction temperature is rated at +150°C, limiting continuous power dissipation to ~320mW at +85°C ambient.
Can OPA2613IDRG4 be used in differential I/Q amplifier configurations?
Yes, OPA2613IDRG4 is explicitly validated for differential I/Q amplifier use: its matched dual channels achieve < −80dBc input-referred crosstalk at 1MHz and deliver >14-bit dynamic range through 5MHz in differential configurations. Application diagrams (Figures 5–7) confirm use in baseband I/Q receivers with GD = +4, RL = 70Ω, and ≤ −95dBc harmonic distortion - meeting LTE and WiMAX front-end requirements.
Is OPA2613IDRG4 pin-compatible with TS613 or other legacy xDSL drivers?
No, OPA2613IDRG4 is not pin-compatible with TS613. While the datasheet notes "TS613 improved replacement" in marketing context, the pinout differs: TS613 uses an 8-pin SOIC but assigns pins differently (e.g., separate shutdown, different supply pin locations). OPA2613IDRG4 follows standard dual-op-amp SO-8 pinout (pin 1 = +VS, pin 8 = −VS), whereas TS613 has non-standard pin mapping requiring PCB redesign for substitution.
