What are the key features of OPA301AIDRG4?

  • 150 MHz gain-bandwidth product for wideband signal amplification in data acquisition front-ends and active filter designs
  • Ultra-low 5 fA input bias current (IIB) enabling precision high-impedance sensor interfaces without leakage-induced offset
  • 80 dB typical common-mode rejection ratio (CMRR) for robust noise rejection in differential measurement systems

What is OPA301AIDRG4 used for?

OPA301AIDRG4 is suited for precision signal conditioning in data acquisition systems, photodiode transimpedance amplifiers, and medical instrumentation where low input bias current and wide bandwidth must coexist. Its 150 MHz bandwidth supports active anti-aliasing filters ahead of high-speed ADCs in industrial measurement equipment. The 8-pin SOIC package in Green packaging (G4 suffix) meets RoHS requirements for modern PCB assembly.

Frequently Asked Questions

For a photodiode transimpedance amplifier design, how does OPA301AIDRG4's 5 fA bias current affect measurement accuracy?

OPA301AIDRG4's maximum input bias current (IIB) of 5 fA (0.000005 µA) is extremely low. In a transimpedance amplifier with a 1 MΩ feedback resistor, this bias current contributes only 5 nV of output offset — negligible compared to the 7000 µV input offset voltage. This makes OPA301AIDRG4 excellent for high-impedance photodiode circuits where picoampere-level leakage is unacceptable.

Can OPA301AIDRG4's 150 MHz bandwidth support active anti-aliasing filters for 10 MSPS ADCs?

Yes. With a 150 MHz gain-bandwidth product, OPA301AIDRG4 can implement active low-pass filters with cutoff frequencies up to several MHz at unity gain, well above the Nyquist frequency of a 10 MSPS ADC (5 MHz). At a gain of 2, the usable bandwidth is approximately 75 MHz, still more than adequate for anti-aliasing ahead of most high-speed 12-bit to 16-bit converters.

How does OPA301AIDRG4's 80 dB CMRR compare to general-purpose op-amps in an industrial differential measurement scenario?

OPA301AIDRG4 achieves 80 dB typical CMRR (minimum 66 dB), meaning common-mode interference at 60 Hz mains frequency is attenuated by a factor of 10,000. General-purpose voltage-feedback op-amps typically offer 60–70 dB CMRR. In industrial 4–20 mA loop measurements or strain gauge bridges, the extra 10–20 dB of OPA301AIDRG4 translates to significantly better rejection of power-line noise.

What are the procurement details for OPA301AIDRG4 including package type and RoHS compliance status?

OPA301AIDRG4 comes in an 8-pin SOIC (R-PDSO-G8) package — the 'G4' suffix denotes Green (lead-free, halogen-free) packaging per Texas Instruments' naming convention, meeting RoHS and REACH requirements. It ships on tape and reel for automated SMT assembly. The YTEOL value of 0 indicates it is an actively produced part with no announced end-of-life, making it suitable for long-term production commitments.
