Product details
Overview
OPA2830IDGKR 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 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 OPA2830IDGKR datasheet, OPA2830IDGKR pinout, OPA2830IDGKR application, or OPA2830IDGKR equivalent, key selection criteria include single-supply 3V–11V operation, ground-referenced input range, distortion performance scaling with signal swing, and VSSOP-8 thermal performance (RθJA = 144.1°C/W).
Technical Context
The OPA2830IDGKR employs complementary common-emitter output stages enabling rail-to-rail output swing into 150Ω loads while maintaining low differential gain/phase error-critical for consumer video. Its high GBW (100MHz) and fast settling (44ns to 0.1% at G = +2) support precision sampling in 3V/5V CMOS ADC front-ends.
Input stage design allows operation with input voltages extending below the negative rail and to within 1.8V of the positive rail. Distortion improves at lower signal swings-a distinguishing trait versus competing low-power op amps-and is validated across 5MHz, 10MHz, and 20MHz two-tone intermodulation tests.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2832IDGKR | Fixed-gain (G = +2) configuration; higher PSRR (72dB); same VSSOP-8 package and 230MHz BW | Optimized for line driver use cases only; not configurable for variable-gain ADC buffering | Select OPA2832IDGKR when fixed +2 gain and improved supply rejection are required; not a drop-in replacement for programmable gain stages |
| LMH6629MA/NOPB | Higher bandwidth (1.5GHz), higher supply current (12.5mA), SOIC-8 only; 4.2nV/√Hz noise | Better suited for RF IF amplification or optical receiver TIA feedback; overqualified for 5V ADC buffering | Choose LMH6629MA/NOPB only when >1GHz bandwidth or sub-5nV/√Hz noise is mandatory; adds cost and power overhead for standard video/ADC use |
Compared with OPA2830IDGKR, OPA2832IDGKR trades gain flexibility for enhanced PSRR in fixed-line-driver roles, while LMH6629MA/NOPB provides extreme bandwidth and lower noise at significantly higher power and cost-making OPA2830IDGKR the optimal balance for portable, single-supply, wideband analog signal conditioning.

FAQ
What supply voltage ranges does the OPA2830IDGKR support?
The OPA2830IDGKR operates from 3V to 11V on single supply or ±1.5V to ±5.5V on dual supply. At 5V single supply, it achieves 230MHz small-signal bandwidth and 4.82VPP output swing into 1kΩ. Its input common-mode range extends to ground, making it ideal for direct coupling in 3V–5V systems without level-shifting circuitry.
Does the OPA2830IDGKR support rail-to-rail output swing?
Yes-the OPA2830IDGKR delivers rail-to-rail output swing, reaching within 25mV of either supply rail when driving a 150Ω load. This capability is enabled by its complementary common-emitter output stage and is verified across temperature (–40°C to +85°C) and supply conditions (3V, 5V, ±5V). Output swing remains >4.7VPP on 5V supply even into 150Ω.
How does distortion performance scale with output amplitude in the OPA2830IDGKR?
Unlike most op amps, the OPA2830IDGKR exhibits improving harmonic distortion as output signal amplitude decreases. At 5MHz, 2VPP output yields –52dBc 2nd-harmonic distortion, while 0.5VPP reduces it to –60dBc. This behavior is confirmed in TI's SBOS309E datasheet Figures 6-29 through 6-32 and makes the OPA2830IDGKR especially effective in AGC or variable-gain signal paths.
What is the thermal resistance of the OPA2830IDGKR in its VSSOP-8 package?
The OPA2830IDGKR in DGK (VSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 144.1°C/W, junction-to-board (RθJB) of 77.6°C/W, and junction-to-case (top) (RθJC(top)) of 56.2°C/W. These values are measured per JEDEC JESD51 standards and confirm suitability for thermally dense layouts without heatsinking at 8.8mA quiescent current.
Can the OPA2830IDGKR be used in differential configurations?
Yes-the OPA2830IDGKR supports fully differential operation using external resistors (e.g., RF = 604Ω per channel per Figure 7-1 in SBOS309E). In differential mode at GD = +2, it achieves 100MHz bandwidth, <–65dBc 2nd-harmonic distortion at 5MHz, and <–75dBc 3rd-harmonic distortion-validated in Figures 6-44 through 6-48 of the datasheet.
