What are the key features of LM321AH?
- Ultra-precision voltage-feedback op-amp with 126dB minimum CMRR for exceptional common-mode noise rejection in sensitive analog circuits
- Extremely low max bias current of 0.15µA and input offset current of 0.01µA for accurate low-leakage signal processing
- Internal frequency compensation enabling stable operation across wide gain configurations without external compensation components
What is LM321AH used for?
The LM321AH precision op-amp is ideal for instrumentation amplifiers, medical measurement equipment, and scientific data acquisition systems where ultra-low bias current and high common-mode rejection are critical. Its voltage-feedback architecture with internal compensation makes it well suited for precision signal conditioning circuits, audio preamplifiers, and low-noise sensor interfaces. The metal can package provides excellent shielding for EMI-sensitive applications in test and measurement equipment.

Frequently Asked Questions
What is the common-mode rejection ratio (CMRR) of the LM321AH?
The LM321AH has a minimum common-mode rejection ratio of 126dB, which is excellent for precision analog applications. This high CMRR ensures that common-mode interference signals are strongly attenuated, making it ideal for differential measurement in noisy industrial or medical environments.
What is the input bias current specification of the LM321AH?
The LM321AH has a maximum input bias current (IIB) of 0.15µA at 25°C and a maximum input offset current (IIO) of 0.01µA. These extremely low values make it suitable for high-impedance source signal conditioning, pH electrode buffers, and precision charge amplifiers.
What package is the LM321AH available in?
The LM321AH is housed in a metal can package, which provides superior electromagnetic shielding compared to plastic packages. This construction makes it preferred for precision RF signal processing, medical instrumentation, and test equipment applications where external EMI must be minimized.
Is the LM321AH a lead-free or RoHS compliant component?
The LM321AH has a Pbfree code of No, meaning it is not a lead-free component. Users should verify environmental compliance requirements before using it in designs targeting EU RoHS-compliant or other lead-restricted markets.
