ISL28230FUZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28230FUZ-T7A is a dual-channel micro-power, zero-drift operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, optimized for single-supply voltages from 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/µs, an input offset voltage of 40 µV, and an input bias current of 250 pA. The device operates within a temperature range of -40°C to +125°C and is housed in an MSOP-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift architecture ensures low input offset voltage and minimal drift over temperature variations.
• Rail-to-rail input and output stages maximize dynamic signal range in low-voltage applications.
• Micro-power consumption with a typical supply current of 20 µA per channel supports battery-operated systems.

Instrumentation, Op Amps, Buffer Amps Applications

• Precision sensor signal conditioning
• Medical instrumentation such as infusion pumps
• Portable handheld devices powered by AA batteries or lithium cells

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging and any distinct marking codes. Confirm that the MSOP-8 package variant matches the required thermal and mechanical specifications for the target PCB layout. Check for obsolescence notices as this component family has faced discontinuation events.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high precision and low power are critical constraints. The zero-drift technology eliminates the need for external chopper stabilization circuits. Ensure the application voltage stays within the 1.8V to 5.5V range to maintain specified performance metrics. Compare against the ISL28230CRZ series if industrial temperature ranges or different packaging formats are required.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x30 family of micro-power, zero-drift amplifiers, which includes single (ISL28130) and quad (ISL28430) channel variants. The family is designed for high-accuracy analog signal processing in portable and battery-powered equipment. Renesas acquired Intersil, the original developer of this line, integrating these components into their broader analog portfolio.
