Frequently Asked Questions
What is the input bias current specification of the LM7322MM?
The LM7322MM has a maximum input bias current (IIB) of 1µA at 25°C and 1.5µA maximum over the full operating temperature range. This low bias current makes it suitable for high-impedance source applications such as photodiode amplifiers and pH sensor interfaces where source loading must be minimized.
What is the common-mode rejection ratio (CMRR) of the LM7322MM?
The LM7322MM specifies a minimum CMRR of 65dB and a typical CMRR of 80dB. This high common-mode rejection makes it effective at suppressing power-supply noise and ground-referenced interference in differential signal amplification, sensor bridges, and instrumentation applications.
Does the LM7322MM require external frequency compensation?
No, the LM7322MM includes internal frequency compensation as indicated by the Frequency Compensation: YES specification. This eliminates the need for external compensation capacitors, reducing component count and simplifying PCB layout while ensuring stable closed-loop operation across a wide range of gain settings.
What package does the LM7322MM come in and where can I buy it?
The LM7322MM is available in an 8-pin Small Outline Package (SOIC, S-PDSO-G8), which offers a compact footprint for surface-mount assembly. It is priced from approximately $1.30 per unit and is available in stock through FindMyChip with worldwide shipping, making it easy to source for both prototyping and production quantities.
What are typical applications for the LM7322MM op-amp?
The LM7322MM is commonly used in precision signal conditioning, active filter design, sensor amplification (thermocouples, strain gauges, photodiodes), data acquisition input stages, audio processing circuits, and medical monitoring equipment. Its dual-channel architecture, low offset voltage of 6mV max, and high CMRR make it versatile for both AC and DC precision analog designs.
