ISL28208FRTZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28208FRTZ-T7A is a dual precision operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail output and input capability extending below the negative supply rail, making it suitable for single-supply applications. The device operates within a voltage range of 3V to 40V and supports a wide operating temperature range from -40°C to +125°C. Packaged in an 8-TDFN (3x3) surface-mount format, it offers low power consumption with a supply current of 850µA for both channels. Key electrical characteristics include a maximum input offset voltage of 40µV, a gain-bandwidth product of 4MHz, and a slew rate of 1.2V/µs.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm package integrity as moisture-sensitive level 2 requires proper handling. Check for obsolescence notices as this part may be subject to production changes. Ensure compatibility with existing PCB footprint and reflow profiles. Validate specifications against latest datasheet revisions before final design approval.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output and sub-ground input are required alongside precision performance. Compare against single-channel variants if only one amplifier is needed. Consider thermal dissipation requirements given the small TDFN package. Evaluate alternative packages like SOIC or MSOP if larger footprints are acceptable for easier assembly. Verify supply voltage constraints match system requirements.
