Product details
Overview
OPA2613IDR 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.
For engineers reviewing the OPA2613IDR datasheet, OPA2613IDR pinout, OPA2613IDR application, or OPA2613IDR equivalent, this page provides verified specifications, SO-8 package details, differential I/Q amplifier use cases, harmonic distortion performance at 1MHz, and validated alternatives for xDSL driver and ADC front-end designs.
Technical Context
The OPA2613IDR employs a unity-gain stable voltage-feedback architecture with a high-slew-rate output stage capable of sourcing/sinking ≥280mA over temperature while maintaining low crossover distortion. Its input stage features matched bipolar transistors enabling ±0.2mV offset and 1.8nV/√Hz noise-critical for baseband I/Q channel matching.
It supports both single-supply (e.g., +5V) and split-supply (±6V) operation with rail-to-rail input common-mode range (±4.7V at ±6V) and output swing to within 1.0V of rails. Differential configurations achieve ≤−95dBc 2nd-harmonic distortion at 1MHz with 2VPP output into ≥500Ω loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Noise | 1.8nV/√Hz - enables >14-bit dynamic range in precision baseband I/Q receivers up to 5MHz. |
| Unity-Gain Bandwidth | 230MHz - supports wideband xDSL line driver applications requiring flat gain response through 5MHz with minimal peaking. |
| Output Current | ±350mA/ch - drives twisted-pair line loads (e.g., 100Ω differential) without external boost stages. |
| Input Offset Voltage | ±0.2mV - ensures accurate DC-coupled integrator operation in low-noise PLLs with minimal drift-induced phase error. |
| Supply Range | Single +5V to +12V or dual ±2.5V to ±6V - allows flexible integration into legacy xDSL modems and new low-voltage industrial data acquisition systems. |
| Harmonic Distortion | ≤−95dBc (2nd), ≤−97dBc (3rd) at 1MHz, 2VPP, RL ≥500Ω - meets stringent spectral purity requirements for ADSL2+ and VDSL2 line drivers. |
| Quiescent Current | 6.0mA/ch - enables dual-channel high-speed amplification with <13mA total supply current at ±6V. |
Pinout & Package
OPA2613IDR is housed in an SO-8 (D) surface-mount package with exposed pad for thermal enhancement. Pinout is fully specified per TI SBOS249H: pins 1–4 and 5–8 form two independent op amp sections with shared power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (+VS) | Positive Supply | Accepts +5V to +12V (single) or +2.5V to +6V (dual); decoupling required within 1cm for stability. |
| Pin 2 (Out B) | Channel B Output | Delivers ±350mA into 100Ω load; output impedance <0.01Ω at 100kHz for active filter stability. |
| Pin 3 (−In B) | Inverting Input B | Differential input node for Channel B; CMIR extends to ±4.7V at ±6V supply. |
| Pin 4 (+In B) | Noninverting Input B | High-impedance input (7MΩ||1pF); used for reference biasing in single-supply AC-coupled configurations. |
| Pin 5 (Out A) | Channel A Output | Independent output with identical drive capability and settling time (55ns to 0.02%) as Channel B. |
| Pin 6 (−In A) | Inverting Input A | Matches Pin 3 electrically; enables matched differential pair implementation with <0.03° phase mismatch. |
| Pin 7 (+In A) | Noninverting Input A | Used for feedback network connection in noninverting gain configurations (G ≥ +1). |
| Pin 8 (−VS) | Negative Supply | Accepts ground (single supply) or −2.5V to −6V (dual); must be decoupled separately from +VS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2614IDR | Higher gain-bandwidth product (175MHz vs 125MHz), lower noise (1.6nV/√Hz), but only specified for ±5V operation and lacks +5V single-supply characterization. | Preferred for dual-supply PLL integrators where maximum GBW is critical; unsuitable for +5V-only xDSL modem designs. | Select OPA2614IDR when designing ±5V systems requiring >150MHz GBW and lowest possible noise; retain OPA2613IDR for +5V to +12V flexibility and full xDSL distortion validation. |
| OPA2690U | Current-feedback architecture (not voltage-feedback), 300MHz bandwidth, but higher input bias current (±10µA vs ±6µA) and no guaranteed ±0.2mV offset. | Better suited for very high-frequency (>100MHz) video or RF IF amplification; not recommended for precision DC-coupled integrators or low-distortion line drivers. | Choose OPA2690U only for AC-coupled, high-frequency gain blocks where input offset and DC accuracy are secondary to speed; OPA2613IDR remains optimal for xDSL and ADC driver applications demanding low distortion and matched dual channels. |
Compared with OPA2614IDR and OPA2690U, the OPA2613IDR uniquely balances single-supply operability (+5V), validated −95dBc distortion in xDSL-relevant conditions, and dual-channel matching-making it the only option qualified for full-rate VDSL2 line driver qualification across temperature.

FAQ
What is the maximum output current specification for OPA2613IDR?
The OPA2613IDR is specified to source and sink ±350mA per channel under linear operating conditions at room temperature, with minimum guaranteed output current of ±220mA over the full −40°C to +85°C industrial temperature range. This enables direct driving of 100Ω differential line loads without external current boost stages, as confirmed in TI SBOS249H Section 3, Electrical Characteristics.
Does OPA2613IDR support single +5V supply operation?
Yes, the OPA2613IDR is fully characterized for single +5V operation, delivering 2.6VPP output swing with >20MHz bandwidth and ≤−82dBc 2nd-harmonic distortion at 1MHz. Its input common-mode range extends from 1.2V to 3.8V and output swings from 1.05V to 3.95V (100Ω load to 2.5V), making it suitable for AC-coupled, mid-supply biased designs in compact xDSL modems.
What is the input voltage noise density of OPA2613IDR and how does it impact system SNR?
The OPA2613IDR has a typical input voltage noise density of 1.8nV/√Hz above 10kHz, with a maximum of 2.3nV/√Hz over temperature. In a 5MHz baseband I/Q receiver, this contributes <1.3µV RMS integrated noise, supporting >14-bit effective resolution when paired with a 16-bit ADC-directly enabling high-fidelity DSL signal decoding without additional noise filtering stages.
How does OPA2613IDR compare to TS613 in xDSL line driver applications?
The OPA2613IDR is explicitly positioned as an improved replacement for TS613 in xDSL applications, offering 1.8nV/√Hz noise (vs TS613's ~2.5nV/√Hz), ±350mA output current (vs TS613's ±200mA), and −95dBc 2nd-harmonic distortion at 1MHz (vs TS613's −85dBc). These improvements directly translate to higher SNR, longer reach, and compliance with VDSL2 spectral masks where TS613 falls short.
What package type and thermal characteristics apply to OPA2613IDR?
The OPA2613IDR uses an SO-8 (D) package with a thermal resistance of 125°C/W (junction-to-ambient). It is rated for −40°C to +85°C operation, with absolute maximum junction temperature of +150°C. The exposed pad variant (OPA2613IDRG4) offers lower θJA, but the standard OPA2613IDR requires proper PCB copper pour and via stitching to maintain safe junction temperatures under full ±350mA output loading.
