ISL28227FBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28227FBZ-T7A is a dual-channel precision operational amplifier manufactured by Renesas Electronics Corporation. It features a gain-bandwidth product of 10 MHz and a slew rate of 3.6 V/µs. The device operates with a supply voltage range from 4.5 V to 40 V and draws 2.2 mA of supply current for both channels. Key electrical specifications include an input offset voltage of 10 µV, input bias current of 1 nA, and output current per channel of 45 mA. It is housed in an 8-SOIC package and supports an operating temperature range of -40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly as Renesas Electronics Corporation is the sole producer. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure compatibility with RoHS3 compliance requirements if mandated by your project standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel precision is required alongside low noise characteristics. Compare against single-channel alternatives if only one amplifier is needed to reduce cost. Consider the 10 MHz bandwidth sufficient for most sensor interfaces but verify against higher speed requirements. Evaluate the 45 mA output drive capability against load requirements to ensure stability.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28227 series of precision amplifiers from Renesas. It is the dual-channel variant of the ISL28127 single-channel amplifier. The family is designed for applications demanding high accuracy and low power consumption. It replaces older Intersil parts under the same naming convention after the company acquisition.
