Texas Instruments OPA2830ID

Overview

OPA2830ID 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, ±75mA output drive, and rail-to-rail output swing within 25mV of either supply on 5V operation.

For engineers reviewing the OPA2830ID datasheet, OPA2830ID pinout, OPA2830ID application, or OPA2830ID equivalent, this page provides verified electrical specifications, VSSOP-8 package layout, dual-channel functional role in signal conditioning chains, and validated alternatives for low-power high-speed analog front-end design.

Technical Context

The OPA2830ID employs complementary common-emitter output stages to achieve fast settling (44ns to 0.1%), low distortion (–58dBc 2nd-harmonic at 5MHz), and robust output drive into 150Ω loads. Its input stage operates down to ground on single supply and extends to within 1.8V of V_S+, enabling direct interfacing with 3V CMOS ADCs and CCD sensors.

Designed for flexible supply operation (3V to 11V single or ±1.5V to ±5.5V dual), it maintains stable AC performance across temperature (–40°C to +85°C) and supply variations, with PSRR >61dB and CMRR >76dB - critical for mixed-signal systems where power rail noise and common-mode interference must be rejected.

FAQ

What is the maximum recommended supply voltage for OPA2830ID?

The absolute maximum supply voltage for OPA2830ID is ±6.5V for dual supply or 11V for single supply. However, the recommended operating range is 3V to 11V single supply or ±1.5V to ±5.5V dual supply. Operating beyond ±6.5V or 11V risks permanent damage, and performance is not guaranteed outside the recommended conditions specified in the datasheet for OPA2830ID.

Does OPA2830ID support true rail-to-rail input operation?

OPA2830ID does not provide rail-to-rail input - its input common-mode range extends to ground and within 1.8V of the positive supply (e.g., up to 3.2V on a 5V supply). This enables ground-referenced inputs but excludes full V_S+–to–ground coverage. The output, however, swings to within 25mV of both rails under 150Ω load, satisfying rail-to-rail output requirements for OPA2830ID.

Can OPA2830ID drive a 75Ω video load directly?

Yes, OPA2830ID can drive a 75Ω video load directly: it delivers ±75mA output current and sustains rail-to-rail swing into 150Ω, meaning it comfortably meets SMPTE/ITU 1V_PP video drive requirements into 75Ω with appropriate gain-setting resistors. Layout best practices (short traces, local 0.1µF + 10µF decoupling) are essential to maintain stability and low distortion for OPA2830ID in this role.

What is the typical harmonic distortion performance of OPA2830ID at 5MHz?

At 5MHz, 2V_PP output, and 150Ω load, OPA2830ID achieves –52dBc 2nd-harmonic and –50dBc 3rd-harmonic distortion under 5V supply. Performance improves with higher load resistance (e.g., –56dBc HD2 at 500Ω) and degrades slightly at lower supplies (–56dBc HD2 at 3V). These values are measured per standard test conditions defined in the OPA2830ID datasheet and reflect its suitability for high-fidelity signal paths.

Is thermal performance different between SOIC-8 and VSSOP-8 packages for OPA2830ID?

Yes - the VSSOP-8 (DGK) package has higher thermal resistance than SOIC-8 (D): R_θJA is 144.1°C/W vs. 122.6°C/W. This means the VSSOP-8 runs ~21°C hotter at the same power dissipation and ambient condition. For continuous high-output-current operation (>50mA), PCB copper area and thermal vias beneath the exposed pad are strongly recommended to manage junction temperature in OPA2830ID designs using the DGK variant.
