What are the key features of OPA830IDG4?
- Voltage-feedback architecture with 80dB typical CMRR enables precise signal amplification in single-supply systems
- Low-power design with internal frequency compensation reduces external component count and design complexity
- 8-pin SOIC (R-PDSO-G8) package allows straightforward PCB integration with standard 1.27mm pitch footprint
- 10µA maximum bias current at 25°C minimizes input loading on high-impedance signal sources
What is OPA830IDG4 used for?
OPA830IDG4 is suited for low-power, single-supply signal conditioning in battery-operated instruments, portable data acquisition systems, and sensor interface circuits. Its 80dB CMRR makes it effective for amplifying differential signals in the presence of common-mode noise, such as in industrial 4-20mA current loop receivers and strain-gauge bridge amplifiers. The voltage-feedback architecture and internal frequency compensation simplify gain-bandwidth trade-off decisions in active filter and transimpedance amplifier designs.

Frequently Asked Questions
What CMRR performance does OPA830IDG4 provide and why does it matter for differential signal applications?
OPA830IDG4 achieves 80dB typical common-mode rejection ratio (CMRR) and a minimum of 73dB. This 80dB CMRR means the amplifier suppresses common-mode interference by a factor of 10,000:1, which is critical in industrial sensor applications such as thermocouple amplification and bridge measurements where power-line noise is superimposed on the signal.
How does the 10µA bias current of OPA830IDG4 affect signal conditioning circuit design?
With a maximum bias current of 10µA at 25°C (13µA average maximum), OPA830IDG4 introduces minimal input loading on high-impedance sources. Keeping source resistance below 10kΩ limits offset voltage error from bias current to under 130µV, which is manageable alongside the 8600µV maximum input offset voltage for most non-precision applications.
In which single-supply voltage scenarios is OPA830IDG4 appropriate compared to rail-to-rail output alternatives?
OPA830IDG4 suits applications where the signal swing stays within the linear range of a standard op-amp output stage on 3V to 5V single supply, such as AC-coupled audio buffering and medium-bandwidth filtering at frequencies below the gain-bandwidth product. Where output must swing within millivolts of the supply rails, a rail-to-rail output op-amp such as OPA348 would be a better choice.
What package does OPA830IDG4 use and how does the G4 suffix affect ordering?
OPA830IDG4 uses the 8-pin SOIC (R-PDSO-G8) package with a 1.27mm pin pitch and approximately 4.9mm x 3.9mm body. The 'G4' suffix in the MPN indicates a tape-and-reel packaging variant with 2500 units per reel, which is preferred for automated SMT assembly lines handling high-volume production.
