Product details
Overview
OPA2613IDTJ from Texas Instruments is a dual, wideband, voltage-feedback operational amplifier optimized for xDSL differential line driving and high-fidelity 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 robust twisted-pair line driving in broadband access equipment.
For engineers reviewing the OPA2613IDTJ datasheet, OPA2613IDTJ pinout, OPA2613IDTJ application, or OPA2613IDTJ equivalent, this page provides verified specifications, SO-8 package terminal mapping, differential I/Q amplifier use cases, harmonic distortion performance at 1MHz, and validated alternatives for xDSL driver and precision ADC front-end designs.
Technical Context
The OPA2613IDTJ employs a unity-gain stable voltage-feedback architecture with a low-noise, high-slew-rate output stage capable of sourcing/sinking ±350mA while maintaining ≤ −95dBc 2nd-harmonic distortion into ≥500Ω loads at 1MHz. Its input stage features matched bipolar transistors enabling <±1.2mV offset over −40°C to +85°C and CMRR ≥86dB.
Designed for differential configurations, it supports gain-of-4 differential amplification with <−95dBc distortion up to 2VPP output swing into 70Ω, and achieves >20MHz large-signal bandwidth on +5V supply driving 100Ω loads - critical for baseband I/Q channel matching and 16-bit ADC driver applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 1.8nV/√Hz at f >10kHz - enables ultra-low-noise signal amplification in PLL integrators and precision receivers. |
| Unity-Gain Bandwidth | 230MHz - supports wideband AC-coupled line drivers and video-frequency active filters without stability compensation. |
| Output Current (per channel) | ±350mA linear sourcing/sinking - drives heavy twisted-pair loads (e.g., 100Ω differential) without clipping or thermal shutdown. |
| Input Offset Voltage | ±0.2mV (max at +25°C) - ensures DC accuracy in precision integrators and low-drift baseband amplifiers. |
| Supply Range | Single +5V to +12V or dual ±2.5V to ±6V - allows flexible integration in legacy xDSL modems and new low-voltage embedded systems. |
| Harmonic Distortion (2nd) | ≤ −95dBc at 1MHz, 2VPP, RL ≥500Ω - meets stringent spectral purity requirements for ADSL2+ and VDSL2 line drivers. |
| Quiescent Current | 6.0mA per channel - enables dual-channel operation at <12.8mA total, reducing thermal load in space-constrained DSLAM cards. |
Pinout & Package
OPA2613IDTJ is housed in an SO-8 (D) surface-mount package with exposed pad for thermal enhancement, rated for −40°C to +85°C operation and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+VS) | Positive Supply Rail | Accepts +5V to +12V (single) or +6V max (dual); internal biasing remains stable across full range. |
| 2 (Out B) | Channel B Output | Delivers ±350mA into 100Ω; output swing reaches within 1.0V of rails on +5V supply. |
| 3 (−In B) | Inverting Input B | Differential pair input node; common-mode range extends to ±4.4V at temperature extremes. |
| 4 (+In B) | Noninverting Input B | Matches −In B offset and drift; used for single-ended or differential feedback configurations. |
| 5 (Out A) | Channel A Output | Independent output with identical drive capability and distortion performance as Out B. |
| 6 (−In A) | Inverting Input A | Electrically isolated from Channel B; crosstalk ≤−80dBc at 1MHz supports matched I/Q channels. |
| 7 (+In A) | Noninverting Input A | Enables independent gain-setting for each channel in dual-path receiver or transmitter circuits. |
| 8 (−VS) | Negative Supply Rail | Accepts 0V (single-supply ground) or −6V max (dual); PSRR ≥87dB rejects supply ripple. |

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 |
|---|---|---|---|
| OPA2677ID | Current-feedback architecture; 1.6GHz gain-bandwidth, lower 1.6nV/√Hz noise, but requires careful feedback resistor selection and lacks rail-swing output stage. | Better for >100MHz closed-loop designs with fixed gain; unsuitable for low-distortion differential line driving below 20MHz due to higher harmonic content. | Select OPA2677ID only when bandwidth >500MHz is required and layout supports strict CFB stability rules. |
| OPA2690ID | Voltage-feedback like OPA2613IDTJ; 1.3GHz GBW, 2.1nV/√Hz noise, ±250mA output, no integrated current limiting, higher quiescent current (11mA/ch). | Higher bandwidth suits wideband test equipment; lower output current and missing current-limit protection reduce suitability for DSL line fault conditions. | Choose OPA2690ID for instrumentation-grade AC coupling where peak slew rate >1000V/µs is critical and fault tolerance is secondary. |
Compared with OPA2613IDTJ, OPA2677ID offers higher bandwidth but demands more complex layout and lacks built-in current limiting, while OPA2690ID trades output drive strength and fault protection for raw speed - making OPA2613IDTJ the optimal choice for xDSL line drivers requiring robustness, low distortion, and supply flexibility.

FAQ
What is the maximum output current capability of the OPA2613IDTJ per channel?
The OPA2613IDTJ delivers ±350mA linear output current per channel into resistive loads, with short-circuit current reaching ±500mA. This is verified under ±6V supply conditions with junction temperature ≤+150°C. The device includes internal current limiting to protect against sustained overload, making OPA2613IDTJ suitable for driving twisted-pair lines subject to fault conditions in xDSL applications.
Does the OPA2613IDTJ support single +5V supply operation?
Yes, the OPA2613IDTJ is fully specified for single +5V operation, delivering 2.6VPP output swing with >20MHz bandwidth into 100Ω loads. Its input common-mode range extends from 1.2V to 3.5V and output swings from 1.05V to 3.7V (100Ω to 2.5V), enabling AC-coupled configurations with mid-supply biasing - a key feature confirmed in the +5V Electrical Characteristics table of the SBOS249H datasheet.
What is the harmonic distortion performance of the OPA2613IDTJ at 1MHz?
At 1MHz, 2VPP differential output, and RL ≥500Ω, the OPA2613IDTJ achieves ≤−95dBc 2nd-harmonic distortion and ≤−97dBc 3rd-harmonic distortion under ±6V supply. On +5V supply, it maintains ≤−82dBc 2nd-harmonic and ≤−94dBc 3rd-harmonic under identical conditions - performance directly supporting ITU-T G.992.x compliance for ADSL/VDSL line drivers.
Is the OPA2613IDTJ pin-compatible with the TS613?
Yes, the OPA2613IDTJ is explicitly documented as an improved replacement for the TS613 in the datasheet's "TS613 IMPROVED REPLACEMENT" section. Both devices share identical SO-8 (D) pinout, supply voltage ranges, and functional block diagram - allowing drop-in substitution with enhanced noise (1.8nV/√Hz vs. ~2.5nV/√Hz), bandwidth (230MHz vs. ~150MHz), and output current (±350mA vs. ±200mA) performance.
What thermal considerations apply to the OPA2613IDTJ in SO-8 package?
The OPA2613IDTJ in SO-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 125°C/W. At maximum quiescent current (13mA total) and worst-case power dissipation, board-level copper area and airflow must limit ambient temperature to ≤+85°C to keep junction temperature below +150°C. The exposed pad variant (IDTJ) improves thermal performance versus standard ID/IDR variants, enabling higher continuous output current in compact DSLAM card layouts.
