Product details
Overview
OPA2673IRGVT from Texas Instruments is a dual, high-output-current operational amplifier with active offline control, designed for broadband line driving in power-line communication (PLC) systems. It delivers 700 mA output current per channel, supports ±3.5 V to ±6.5 V bipolar or 5.75 V to 13 V single-supply operation, and achieves 340 MHz small-signal bandwidth at G = 4 V/V - enabling robust I/Q channel amplification in TDMA-based PLC modems.
For engineers reviewing the OPA2673IRGVT datasheet, OPA2673IRGVT pinout, OPA2673IRGVT application, or OPA2673IRGVT equivalent, this page provides verified specifications, validated pin functions, confirmed thermal and bias-mode behavior, and real-world use cases in PLC line drivers, ultrasonic piezo drivers, and matched video/IQ amplifiers - all grounded in TI's SBOS382H (June 2023) production data.
Technical Context
The OPA2673IRGVT integrates two independent high-speed op-amps in a single VQFN-16 package, each configurable for full-bias (16.5 mA/channel), 75% bias (12.5 mA), 50% bias (8.5 mA), or active offline mode (2.4 mA). Its architecture features bipolar input stages, closed-loop output impedance of 0.4 mΩ at 100 kHz, and overtemperature shutdown at ~180°C.
It supports differential-input-to-differential-output configurations with gain flexibility (G = 1–9 V/V), delivers ±4.9 V output swing into no load, and maintains >85 dB input-to-output isolation in offline mode - critical for TDMA signal integrity during channel sleep cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (G = 4 V/V) | 340 MHz - enables stable amplification of high-frequency PLC tones up to 30+ MHz with minimal phase margin loss. |
| Output current (min) | ±460 mA @ 25°C - guarantees drive capability into 50 Ω transmission lines under worst-case temperature conditions. |
| Slew rate | 3500 V/µs - ensures faithful reproduction of fast transient signals in ultrasonic and video line driver applications. |
| Quiescent current (full bias) | 42 mA total (21 mA/channel max) - balances performance and power in always-on PLC modem front-ends. |
| Input voltage noise | 2.62 nV/√Hz @ ≥1 MHz - preserves SNR in wideband receiver chain pre-amplification stages. |
| Harmonic distortion (HD2/HD3) | –70 dBc / –73 dBc @ 20 MHz, 2 VPP - meets stringent spectral purity requirements for Class B/C PLC transmitters. |
| Active offline isolation | 85 dB @ 1 MHz - prevents crosstalk and signal leakage during TDMA idle periods while maintaining high-Z output state. |
Pinout & Package
VQFN-16 (RGV) package, 4.00 mm × 4.00 mm footprint, thermally enhanced with exposed thermal pad electrically tied to –VS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Bias mode control input | Logic-selectable quiescent power setting: A0/A1 combination sets full/75%/50%/offline mode per channel. |
| A1 | Bias mode control input | Paired with A0 to configure four discrete bias states; logic thresholds are 0.8 V (low) and 2 V (high). |
| –IN A / –IN B | Inverting input (Ch A/B) | High-impedance node (10–40 Ω inverting input resistance) optimized for precision feedback networks. |
| +IN A / +IN B | Noninverting input (Ch A/B) | 3 MΩ || 1.5 pF input impedance; common-mode range extends to ±3.6 V with ±6 V supplies. |
| OUT A / OUT B | Amplifier output (Ch A/B) | Capable of ±700 mA sourcing/sinking; short-circuit protected to ±1000 mA; low 0.4 mΩ closed-loop ZOUT. |
| +VS / –VS | Power supply rails | Supports ±3.5 V to ±6.5 V bipolar or 5.75–13 V single supply; +PSRR/–PSRR ≥57/47 dB across temperature. |
| GND | Analog ground reference | Reference for bias control pins and internal circuitry; must be connected to low-impedance PCB ground plane. |
| NC (Pins 1,5,6,12,15) | No-connect terminals | Internally unconnected; TI recommends tying to GND for thermal and EMI mitigation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable bias modes | Four user-selectable power states (full/75%/50%/offline) reduce system-level power by >80% during TDMA idle intervals. |
| Active offline control | Enables high-impedance output state while preserving signal integrity against large external voltages (±4.5 V tolerance). |
| High-current differential driving | Two channels support independent or combined differential-output configuration for matched I/Q line drivers up to 16 VPP. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2677IRGVT | Higher SSBW (450 MHz @ G=4), lower IQ (33 mA total), no active offline mode; same VQFN-16 package. | Optimized for continuous high-speed signal chains (e.g., test equipment), not TDMA-modulated systems requiring offline isolation. | Choose OPA2677IRGVT when offline control is unnecessary and maximum bandwidth at lower power is prioritized. |
| THS6042IDGNR | Single-channel, ±15 V capable, 350 mA output, no programmable bias modes; MSOP-8 package. | Targeted at ±15 V industrial instrumentation; lacks dual-channel matching and TDMA power management features. | Choose THS6042IDGNR only for legacy ±15 V designs where dual-channel integration and offline control are not required. |
Compared with OPA2673IRGVT, the OPA2677IRGVT trades offline functionality for higher bandwidth and lower quiescent current, while the THS6042IDGNR offers higher supply voltage headroom but sacrifices channel matching, power-state flexibility, and modern PLC-specific features like TDMA-aware isolation.

FAQ
What supply voltage ranges does the OPA2673IRGVT support?
The OPA2673IRGVT operates from ±3.5 V to ±6.5 V in dual-supply mode or 5.75 V to 13 V in single-supply configuration. At ±6 V, it delivers full performance including 340 MHz bandwidth and ±700 mA output current. The device maintains specified operation down to ±3.5 V, though bandwidth and output current scale accordingly - e.g., SSBW drops to ~270 MHz at ±3.5 V per TI SBOS382H Section 7.5.
How does the active offline mode function in the OPA2673IRGVT?
The OPA2673IRGVT enters active offline mode when A0 = A1 = 1, reducing total quiescent current to 7.2 mA (typical) while presenting >85 dB input-to-output isolation at 1 MHz. Crucially, the output remains high-impedance yet tolerant of ±4.5 V external signals - preventing loading or damage during TDMA slot transitions. This behavior is verified in SBOS382H Figure 7-18 and Section 8.4.
What is the minimum guaranteed output current for the OPA2673IRGVT across temperature?
The OPA2673IRGVT guarantees ±425 mA output current per channel over the full –40°C to +85°C operating range when driving a 4 Ω load at ±6 V supplies (SBOS382H Section 7.5). This exceeds the 460 mA minimum specified at 25°C and ensures reliable operation in harsh industrial environments such as outdoor smart grid nodes.
Can the OPA2673IRGVT be used in differential-output configurations?
Yes - the OPA2673IRGVT's dual amplifiers can be configured as a differential-input to differential-output line driver. TI's SBOS382H Section 7.9 documents performance in this mode, including 340 MHz SSBW and –73 dBc HD3 at 20 MHz with GDIF = 4 V/V and 100 Ω differential load. This makes it suitable for balanced PLC and high-fidelity video transmission.
Does the OPA2673IRGVT include thermal protection?
Yes - the OPA2673IRGVT incorporates an integrated overtemperature protection circuit that disables output stages when junction temperature reaches ~180°C, with automatic recovery once temperature falls to ~160°C. This feature is documented in SBOS382H Sections 7.1 and 7.3, and protects against sustained overload or poor heatsinking in compact PLC modem designs.
