ISL28268FUZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28268FUZ is a dual-channel, low-voltage operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. The device operates within a supply voltage range of 2.7 V to 5.5 V, with an input offset voltage of 3 mV maximum. It draws a typical supply current of 40 µA per channel and provides an output short-circuit current of 40 mA. The component is housed in an 8-MSOP package and supports operation from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel or tube packaging configuration, as this affects handling procedures. Ensure the requested quantity aligns with the manufacturer's standard packing unit to avoid partial reel issues. Confirm RoHS compliance status matches project requirements. Check for any recent product change notifications regarding marking or assembly updates before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail performance is required at supply voltages below 5.5 V. The low power consumption makes it suitable for battery-operated devices where extended life is critical. Compare the 1 MHz bandwidth against application signal frequencies to ensure adequate phase margin. Consider the 8-MSOP footprint constraints during PCB layout design to maintain thermal performance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL282xx series of low-power operational amplifiers from Renesas. It shares architectural similarities with single-channel variants like the ISL28168 and quad-channel versions such as the ISL28468. The series emphasizes precision and low power for portable electronics. It complements higher-speed op-amps in Renesas portfolios by focusing on ultra-low current draw rather than high-frequency response.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes include the ISL28268FUZ-T7 for reel-packaged needs. Verify that alternative dual-channel op-amps match the 2.7V minimum supply voltage and rail-to-rail output specifications. Ensure replacement parts maintain the same 8-MSOP package dimensions for board compatibility.
