What are the key features of OPA341NA/3K?
- Rail-to-rail input and output (RRIO) with 5.5MHz bandwidth enabling full signal swing amplification in single-supply low-voltage systems
- Ultra-low input bias current of 10pA at 25C (IIB max 2nA) for accurate high-impedance sensor signal amplification
- 90dB nominal CMRR (76dB min) with internal frequency compensation for stable, high-precision differential signal conditioning
What is OPA341NA/3K used for?
The OPA341NA/3K is well suited for precision signal conditioning of high-impedance sensors such as photodiodes, pH electrodes, and capacitive transducers in portable and battery-powered instrumentation. Its rail-to-rail input/output capability and 5.5MHz bandwidth make it ideal for active filters, instrumentation amplifiers, and data acquisition front ends operating from 3.3V or 5V single supplies. The small SOT-23 package with 15-year longevity support makes it a reliable choice for medical devices, industrial sensors, and IoT edge nodes.

Frequently Asked Questions
What is the bandwidth of the OPA341NA/3K?
The OPA341NA/3K has a gain-bandwidth product of 5.5MHz, which is suitable for audio-frequency signal conditioning, active filter designs, and general-purpose amplification up to the mid-MHz range in single-supply portable and industrial electronics applications.
What is the input bias current of the OPA341NA/3K?
The OPA341NA/3K features an extremely low input bias current of 10pA typical at 25C, with a maximum average bias current of 2nA. This makes it highly suitable for amplifying signals from high-impedance sources such as pH electrodes, photodiodes, and piezoelectric sensors without loading the signal source.
What does rail-to-rail input/output (RRIO) mean for the OPA341NA/3K?
Rail-to-rail input/output means the OPA341NA/3K can accept input voltages and produce output voltages that swing to within millivolts of the supply rails. This maximizes dynamic range in single-supply systems where the signal needs to span the full supply voltage, which is especially important in 3.3V and 5V portable designs.
What package does the OPA341NA/3K come in?
The OPA341NA/3K is available in a 6-pin SOT-23 surface-mount package, which provides a very small PCB footprint. This compact package is well suited for portable medical devices, wearables, and IoT sensor nodes where board space is at a premium.
What is the CMRR of the OPA341NA/3K and why does it matter?
The OPA341NA/3K has a nominal CMRR of 90dB (minimum 76dB), which quantifies how well the amplifier rejects noise or interference that appears equally on both input terminals. High CMRR is critical in differential measurement applications such as bridge sensor amplification, medical biopotential measurement, and instrumentation where supply-coupled noise must be suppressed.
