What are the key features of OPA725AIDBVTG4?
- Rail-to-rail output swing on ±6 V or single 12 V supply maximizes dynamic range in low-voltage signal chains
- 0.2 nA maximum bias current (IIB) enables high-impedance sensor interfacing without signal loading errors
- 94 dB typical CMRR and 84 dB minimum ensure high common-mode rejection for differential signal acquisition
- Compact 5-pin SOT-23 package in tape-and-reel format minimizes PCB area in portable and wearable electronics designs
What is OPA725AIDBVTG4 used for?
The OPA725AIDBVTG4 is ideal for battery-powered instrumentation, portable medical devices, and handheld test equipment requiring rail-to-rail output on supplies from ±6 V to 12 V. Its 0.2 nA ultra-low bias current makes it well-suited for interfacing with high-impedance sensors such as pH electrodes and photodiodes where input leakage must remain below 1 nA. The 5-pin SOT-23 package fits easily into space-constrained designs requiring general-purpose amplification with tight CMRR performance.

Frequently Asked Questions
What supply voltage range and output swing capability does the OPA725AIDBVTG4 support for battery-powered applications?
The OPA725AIDBVTG4 operates from dual supplies of ±6 V or a single 12 V supply and features a rail-to-rail output that swings close to both supply rails. This maximizes the usable output voltage range in low-voltage battery-powered systems, making it suitable for portable instrumentation, medical devices, and data acquisition front-ends running from 5 V or lower supply voltages.
How does the 0.2 nA bias current specification of the OPA725AIDBVTG4 affect high-impedance sensor interface designs?
With a maximum bias current (IIB) of only 0.2 nA at 25°C, the OPA725AIDBVTG4 draws negligible input current from high-impedance sources. This makes it ideal for interfacing with sensors like pH electrodes, photodiodes, and electrochemical cells where input currents above 1 nA would cause measurable voltage errors across source impedances exceeding 1 MΩ, corrupting the measurement result.
What CMRR performance does the OPA725AIDBVTG4 deliver and how does it benefit differential signal acquisition?
The OPA725AIDBVTG4 achieves a typical CMRR of 94 dB and a minimum of 84 dB, meaning common-mode noise on both inputs is rejected by a factor of over 10,000:1. This level of common-mode rejection is essential in instrumentation amplifier topologies and differential sensor interfaces where 50/60 Hz mains interference or ground-loop noise must be suppressed without attenuating the small differential signal of interest.
