MCP618-I/SN

Instrumentation, Op Amps, Buffer Amps Overview

The MCP618-I/SN is a single-channel precision operational amplifier from Microchip Technology, housed in an 8-lead SOIC package. It operates on a single power supply ranging from 2.3V to 5.5V and features rail-to-rail output capability. Key electrical parameters include a maximum input offset voltage of ±150 µV, a gain-bandwidth product of 190 kHz, and a typical quiescent current of 25 µA per amplifier. The device supports an industrial temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'I/SN' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-lead SOIC package type. Confirm that the Chip Select pin requirement aligns with system logic levels before integration. Ensure datasheet revision DS20001613D is referenced for accurate electrical specifications during design validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op amp with integrated shutdown control is required. It is suitable for applications needing low noise and high DC precision under single-supply conditions. Consider alternative packages like MSOP or PDIP if physical footprint constraints differ, while maintaining the same electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MCP616/7/8/9 family of micropower Bi-CMOS operational amplifiers. The MCP618 specifically denotes the single-channel variant equipped with the Chip Select feature. Other family members include the dual MCP617 and quad MCP619, offering similar performance profiles across different channel counts.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MCP616-I/SN (single channel, no CS) and MCP617-I/SN (dual channel). Cross-family replacements require matching GBWP, offset voltage, and package dimensions.
