2N6231

Overview

The MCP6231T-E/OT is a single-channel, low-power operational amplifier manufactured by Microchip Technology. It operates within a supply voltage range of 1.8 V to 5.5 V and features a gain-bandwidth product of 300 kHz with a slew rate of 150 mV/us. Key electrical parameters include an input offset voltage of 5 mV, input bias current of 1 pA, and quiescent current of 20 uA per channel. The device delivers an output current of 23 mA and offers a common-mode rejection ratio of 61 dB with an input voltage noise density of 52 nV/sqrt Hz. It is housed in a SOT-23-5 surface-mount package and supports operating temperatures from -40 C to +125 C.

Procurement Notes

Verify the complete part number including suffixes such as -E/OT to ensure correct packaging and temperature grade. Confirm RoHS compliance status through official datasheets or manufacturer declarations before integration. Cross-reference ordering codes with authorized distributors to avoid counterfeit components. Ensure storage conditions align with moisture sensitivity levels specified in the manufacturing documentation.

Selection Notes

Select this component when a single op-amp solution is required with minimal power draw and moderate bandwidth. Evaluate the 300 kHz gain-bandwidth product against signal frequency requirements to ensure adequate performance. Consider the SOT-23-5 package constraints for PCB layout and thermal management. Compare input offset voltage and bias current specifications against precision needs of the target application.

Part Context

This device belongs to the MCP6231 family of operational amplifiers produced by Microchip Technology. The family focuses on providing cost-effective, low-power solutions for general-purpose analog signal processing. Variants within the series may differ in packaging options or temperature ranges while maintaining core electrical characteristics.

Replacement Considerations

Consult official Microchip documentation for verified equivalent part numbers. Do not assume pin-compatible substitutes without verifying electrical parameter alignment and functional compatibility across the entire operating temperature range.
