ISL28488FVZ-T7

Overview

The ISL28488FVZ-T7 is a quad-channel micropower operational amplifier from Renesas Electronics, optimized for single-supply operation. It features rail-to-rail input and output capabilities, allowing signal swing across the entire supply range. The device operates within a voltage range of 2.4 V to 5.5 V, drawing low quiescent current per channel. Key electrical specifications include a gain-bandwidth product of 0.25 MHz, a slew rate of 0.15 V/µs, and an open-loop voltage gain of 109 dB. It offers a common-mode rejection ratio of 100 dB and functions reliably in temperatures from -40°C to +125°C.

Feature Summary

• Quad-channel configuration with micropower consumption optimized for battery-operated systems
• Rail-to-rail input and output stages enable full dynamic range utilization on single supplies
• High open-loop gain and common-mode rejection ratio ensure precise signal amplification

Applications

• Portable instrumentation requiring low power and wide dynamic range
• Battery-powered sensor interfaces and data acquisition systems
• Industrial process control loops with single-supply constraints

Procurement Notes

Verify the specific suffix T7 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Renesas documentation prior to integration. Check for end-of-life notices or obsolescence warnings, as availability may be limited for legacy components. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Selection Notes

Select this component when a quad-channel solution is required with rail-to-rail performance on a single supply. Compare against dual-channel variants like the ISL28288 if fewer channels suffice. Consider the 0.25 MHz bandwidth limit for high-speed applications where faster op-amps might be necessary. Verify that the 2.4 V minimum supply voltage aligns with the system's power budget.

Part Context

This part belongs to the ISL28488 series of micropower operational amplifiers. It serves as a quad-channel version within Renesas' portfolio of general-purpose analog devices. The series is designed to provide cost-effective solutions for consumer and industrial electronics requiring efficient power management without sacrificing signal integrity.

Replacement Considerations

The ISL28288 is a dual-channel variant within the same family, offering similar electrical characteristics but with only two amplifiers. Cross-reference with other quad-channel micropower op-amps if pin compatibility or specific performance metrics differ significantly.
