ISL28218FBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28218FBZ-T7A is a dual-channel, low-noise operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail output capability and operates within a supply voltage range of 3 V to 40 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 1.2 V/µs, and an input offset voltage of 40 µV. The device draws 850 µA of supply current for both channels and provides a maximum output current of 28 mA per channel. It is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix T7A confirms tape-and-reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Check component lifecycle status, as availability may be limited due to end-of-life conditions. Ensure the 8-SOIC footprint matches the target PCB design constraints before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel amplification with rail-to-rail output is required under high-voltage conditions. The low noise characteristics make it suitable for sensitive analog front-ends. Consider the 8-SOIC package size for space-constrained designs. Evaluate the 4 MHz bandwidth against system speed requirements to ensure adequate performance margins.
