Product details
Overview
OPA830IDBVT from Texas Instruments is a low-power, single-supply, wideband voltage-feedback operational amplifier in a 5-pin SOT-23 package. It delivers 250MHz bandwidth at unity gain, 550V/μs slew rate, and 9.2nV/√Hz input voltage noise on a 5V supply, serving as an ADC input buffer or video line driver in portable 3V/5V systems.
For engineers reviewing the OPA830IDBVT datasheet, OPA830IDBVT pinout, OPA830IDBVT application, or OPA830IDBVT equivalent, key selection criteria include its rail-to-rail output swing (±4.88V on 5V), ground-referenced input on single supply, 3.9mA quiescent current, and validated performance in CCD imaging and ultrasound front-ends.
Technical Context
The OPA830IDBVT uses complementary common-emitter output stage enabling output swing within 25mV of either rail into 150Ω. Its voltage-feedback architecture supports stable operation at gains ≥ +1 with peaking < 2dB at G = +1, and achieves 130MHz gain-bandwidth product in DBV package at 5V supply.
It operates across 2.8V to 11V single supply or ±1.4V to ±5.5V dual supply, with input common-mode range extending to ground and up to 1.7V below V+, making it suitable for DC-coupled signal conditioning where level-shifting is impractical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth (G = +1) | 250MHz - enables high-fidelity signal amplification up to UHF frequencies in ADC driver applications |
| Slew rate | 550V/μs - supports fast transient response for 10-bit+ ADC sampling without slewing-induced distortion |
| Input voltage noise | 9.2nV/√Hz - preserves dynamic range in low-amplitude sensor and imaging channel interfaces |
| Quiescent current | 3.9mA at 5V - balances speed and power for battery-powered instrumentation and portable electronics |
| Output swing (RL = 1kΩ) | ±4.88V on 5V supply - delivers near-rail output compliance for maximum signal headroom in single-supply systems |
| Input common-mode range | Extends to ground on single supply - eliminates need for external biasing in DC-coupled sensor interfaces |
| Gain-bandwidth product | 130MHz (DBV, 5V) - ensures stable closed-loop gain accuracy at higher frequencies than competing low-power op-amps |

| 2 (V–) | Negative supply | Connects to ground in single-supply mode; supports dual-supply operation down to –1.4V |
| 3 (+IN) | Noninverting input | High-impedance node (400kΩ || 1.2pF); accepts DC-coupled signals down to ground potential |
| 4 (–IN) | Inverting input | Used for feedback network connection; matched to +IN for optimal CMRR (76–80dB) |
| 5 (V+) | Positive supply | Accepts 2.8V–11V single supply or +5.5V max in dual-supply configuration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA832IDBVT | Fixed-gain +2 configuration; no external feedback required; 200MHz bandwidth; 4.5mA IQ | Optimized for line driver use only; lacks gain flexibility of OPA830IDBVT's configurable feedback | Select when board space and BOM count reduction outweigh need for adjustable gain |
| LMH6629MA/NOPB | Higher 1.5GHz GBW but 12mA IQ; 1.1nV/√Hz noise; SO-8 only; no ground-swing input | Targeted at RF/IF signal chains requiring ultra-low noise and higher frequency response | Choose only if >1GHz bandwidth and sub-2nV/√Hz noise are mandatory and power budget allows |
Compared with OPA830IDBVT, OPA832IDBVT simplifies layout with fixed gain but sacrifices design flexibility, while LMH6629MA/NOPB trades 3× higher power for 5× lower noise and 6× higher bandwidth-making OPA830IDBVT the optimal balance for portable 3V/5V precision analog front-ends.
