ET358

Instrumentation, Op Amps, Buffer Amps Overview

The ET358 is a low-cost, voltage feedback operational amplifier manufactured by ETEK Microelectronics. It features rail-to-rail input and output (RRIO) capabilities, allowing it to operate from a single supply voltage ranging from 2.1V to 5.5V. The device consumes only 60μA of quiescent current per channel, making it suitable for battery-powered applications. It is housed in an 8-SOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific pinout and electrical characteristics against the official ETEK Microelectronics datasheet before integration. Confirm that the 8-SOP package dimensions match your PCB footprint requirements. Ensure the operating voltage range of 2.1V to 5.5V aligns with your system power rails to guarantee proper functionality.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail signal swing is required at low supply voltages. It is appropriate for designs prioritizing low power consumption over high-speed performance. Compare its 60μA quiescent current and 1MHz bandwidth against other CMOS amplifiers to ensure it meets the specific gain-bandwidth product needs of the application.

Instrumentation, Op Amps, Buffer Amps Part Context

ETEK Microelectronics specializes in high-performance analog integrated circuits. The ET358 belongs to their portfolio of low-cost, general-purpose operational amplifiers designed for mobile and portable devices. This part serves as a modern alternative to traditional bipolar op-amps, offering improved efficiency in low-voltage environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consider the LM358ST for higher voltage tolerance up to 30V, though it lacks rail-to-rail output. For lower power single-supply applications, verify compatibility with other RRIO CMOS amplifiers such as the TLV2372 or MCP6002, ensuring pinout and bandwidth specifications are compatible.
