Texas Instruments OPA2830IDRG4

Overview

OPA2830IDRG4 from Texas Instruments is a dual, low-power, single-supply, wideband voltage-feedback operational amplifier optimized for 3V–5V ADC input buffering and video line driving. It delivers 230MHz small-signal bandwidth at G = +1, 500V/μs slew rate, 9.2nV/√Hz input voltage noise, and rail-to-rail output swing within 25mV of either supply on 5V operation - enabling high-fidelity signal conditioning in portable medical imaging and consumer video systems.

For engineers reviewing the OPA2830IDRG4 datasheet, OPA2830IDRG4 pinout, OPA2830IDRG4 application, or OPA2830IDRG4 equivalent, this page provides verified electrical specifications, VSSOP-8 package layout, real-world use cases in CCD imaging and ultrasound front-ends, and validated alternative options for low-power wideband op-amp selection.

Technical Context

The OPA2830IDRG4 employs complementary common-emitter output stages to achieve fast settling (44ns to 0.1%), low distortion (–58dBc 2nd-harmonic at 5MHz), and robust drive capability (±75mA into 150Ω). Its input stage operates down to ground on single supply and extends to within 1.8V of V_S+, supporting DC-coupled 3V ADC interfaces without level-shifting.

Designed for flexible supply operation (3V to 11V single or ±1.5V to ±5.5V dual), it maintains stable performance across temperature (–40°C to +85°C) with <±22μV/°C offset drift and >76dB CMRR - critical for precision analog front-ends in battery-powered instrumentation.

FAQ

What supply voltages does the OPA2830IDRG4 support?

The OPA2830IDRG4 operates from 3V to 11V single supply or ±1.5V to ±5.5V dual supply. At 5V single supply, it draws 8.8mA quiescent current and delivers 4.82V_PP output swing into 1kΩ. Its input common-mode range extends to ground and within 1.8V of V_S+, enabling true single-supply operation without external bias networks. The OPA2830IDRG4 maintains specified AC performance across this full range.

Does the OPA2830IDRG4 support rail-to-rail input and output?

The OPA2830IDRG4 features rail-to-rail output swing - delivering within 25mV of either supply rail into 150Ω - but does not have rail-to-rail input. Its input common-mode range extends to ground and up to V_S+ – 1.8V, allowing full ground-referenced signal handling on single supply. This makes the OPA2830IDRG4 ideal for DC-coupled sensor interfaces where output headroom is critical but input biasing can be managed externally.

What is the typical harmonic distortion performance of the OPA2830IDRG4 at 5MHz?

At 5MHz, 2V_PP output, and 150Ω load, the OPA2830IDRG4 achieves –52dBc 2nd-harmonic and –50dBc 3rd-harmonic distortion under 5V supply. Distortion improves significantly at lower output amplitudes - dropping to –59dBc (2nd) and –68dBc (3rd) at 1V_PP - a key advantage in variable-gain ultrasound receiver channels. The OPA2830IDRG4 maintains this performance across –40°C to +85°C.

Can the OPA2830IDRG4 drive a 75Ω video line directly?

Yes, the OPA2830IDRG4 can drive a 75Ω video line directly: it delivers ±75mA output current and sustains ±4.60V swing into 150Ω (equivalent to 75Ω differential), meeting SMPTE/NTSC requirements. Its low differential gain/phase error (<0.05%) and 100MHz bandwidth at G = +2 ensure minimal color distortion and group delay variation across 0–5MHz. For sustained 75Ω driving, thermal design using the VSSOP-8 exposed pad is recommended.

How does the OPA2830IDRG4 compare to the OPA2830IDR in terms of packaging and performance?

The OPA2830IDRG4 and OPA2830IDR are functionally identical - both are dual wideband op-amps in VSSOP-8 (DGK) packages with identical electrical specifications, pinout, and thermal characteristics. The "G4" suffix denotes TI's green packaging standard (lead-free, RoHS-compliant, halogen-free), while "DR" indicates tape-and-reel packaging. No performance difference exists between OPA2830IDRG4 and OPA2830IDR; the G4 variant ensures compliance with modern environmental regulations without trade-offs.
