Product details
Overview
OPA2830IDR 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 ultrasound and CCD imaging channels.
For engineers reviewing the OPA2830IDR datasheet, OPA2830IDR pinout, OPA2830IDR application, or OPA2830IDR equivalent, this page provides verified electrical specifications, VSSOP-8 package layout, real-world use cases in single-supply ADC interfaces and video drivers, and validated alternative parts with documented functional trade-offs.
Technical Context
The OPA2830IDR employs complementary common-emitter output stages to achieve ±75mA sourcing/sinking capability and output swing to within 25mV of VS+ or VS− while driving 150Ω loads. Its voltage-feedback architecture supports stable operation at gains ≥ +1 with minimal peaking (4dB at G = +1).
Designed for single-supply systems, it features input common-mode range extending to ground and up to 1.8V below VS+, enabling direct interfacing with 3V/5V CMOS ADCs without level-shifting. Distortion performance improves at lower signal swings - a key differentiator versus competing low-power op amps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2832IDR | Fixed-gain (G = +2) configuration; higher 1.8GHz GBW but no user-selectable gain | Optimized for line driver applications only; lacks flexibility for variable-gain ADC buffering | Select when fixed gain and maximum bandwidth outweigh programmability needs |
| LMH6629MA/NOPB | Higher 1.5GHz GBW and 900V/μs slew rate, but 12.5mA IQ and SOIC-8 only | Better suited for >200MHz RF/IF signal chains; less optimal for battery-powered portable systems | Choose for ultra-high-speed applications where power and package size are secondary |
Compared with OPA2832IDR and LMH6629MA/NOPB, the OPA2830IDR uniquely balances 230MHz bandwidth, 8.8mA quiescent current, and user-configurable gain in a 3mm × 3mm VSSOP package - making it the optimal selection for space- and power-sensitive ADC interface and video driver designs requiring design flexibility.

FAQ
What supply voltage ranges does the OPA2830IDR support?
The OPA2830IDR operates from 3V to 11V on single supply or ±1.5V to ±5.5V on dual supply. At 5V single supply, it draws 8.8mA quiescent current and delivers ±4.6V output swing into 150Ω. Its input common-mode range extends to ground and within 1.8V of VS+, enabling direct interfacing with 0–2.5V sensor outputs without external biasing - a key advantage in portable systems using OPA2830IDR.
Does the OPA2830IDR support rail-to-rail input and output operation?
The OPA2830IDR supports rail-to-rail output swing - delivering within 25mV of either supply rail under 150Ω load - but does not feature rail-to-rail input. Its input common-mode range extends to ground and up to VS+ − 1.8V, allowing true ground-referenced inputs on single supply. This makes OPA2830IDR ideal for ADC front-ends where input signals start at 0V, unlike full rail-to-rail input op amps which sacrifice bandwidth or noise performance.
What is the small-signal bandwidth of the OPA2830IDR at G = +2?
The OPA2830IDR achieves 100MHz small-signal bandwidth at noninverting gain of +2 with VO ≤ 0.2VPP, as specified in the datasheet under VS = 5V conditions. This bandwidth supports high-fidelity amplification of baseband video signals and fast-settling ADC input waveforms. Bandwidth scales inversely with gain: 230MHz at G = +1, 70MHz at G = +5, and 10MHz at G = +10 - all verified in OPA2830IDR's electrical characteristics tables.
How does distortion performance vary with output signal amplitude in the OPA2830IDR?
Unlike most op amps, the OPA2830IDR exhibits improved harmonic distortion at lower output amplitudes: 2nd-harmonic distortion improves from –52dBc to –58dBc when VO drops from 2VPP to 0.5VPP at 5MHz (RL = 150Ω). This behavior - confirmed in Figure 6-30 of the OPA2830IDR datasheet - results from its optimized output stage and makes it especially valuable in variable-gain ADC front-ends where signal levels dynamically change.
Is the OPA2830IDR pin-compatible with other TI dual op amps in VSSOP-8?
The OPA2830IDR uses standard VSSOP-8 pinout (DGK package) with VS+ on pin 8, VS− on pin 4, VOUT1 on pin 1, VOUT2 on pin 7, and differential inputs on pins 2/3 and 5/6 - matching TI's industry-standard dual op amp layout. It is pin-compatible with OPA2832IDR and OPA2822IDR in the same package, enabling drop-in substitution where bandwidth, noise, and supply current requirements align. Always verify gain configuration and stability compensation when replacing OPA2830IDR in existing designs.
