ISL28130FHZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28130FHZ-T7 is a single-channel micropower operational amplifier from the Renesas ISL28x30 series, housed in a SOT-23-5 surface-mount package. It features a gain-bandwidth product of 400 kHz and a slew rate of 200 mV/us. Key electrical parameters include an input offset voltage of 40 uV, input bias current of 700 pA, and supply current of 20 uA per channel. The device supports rail-to-rail input and output operation with a supply voltage range of 1.8 V to 5.5 V (single) or ±0.9 V to ±2.75 V (dual). It offers a common-mode rejection ratio of 125 dB and operates within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range in low-voltage systems
• Micropower consumption with 20 uA supply current per channel for extended battery life
• Low drift characteristics with 40 uV offset voltage and 150 nV/°C drift for high precision

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered handheld devices using 2AA or single lithium-ion cells
• High-performance USB PD power adapters requiring stable analog performance
• Medical infusion pumps demanding precise drug delivery control
• 4-20mA current loop transmitters with ultra-low power MCU integration

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors as the part is marked as obsolete and subject to end-of-life status. Confirm the specific suffix T7 indicates tape-and-reel packaging compatible with automated assembly processes. Ensure the FHZ designation matches the required SOT-23-5 package variant for your PCB layout constraints before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits that require both low power consumption and high precision in a minimal footprint. The SOT-23-5 package suits space-constrained applications where standard SOIC packages are too large. Consider the 400 kHz bandwidth sufficient for low-frequency signal conditioning but insufficient for high-speed data acquisition tasks requiring wider bandwidths.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the ISL28x30 family, which includes dual (ISL28230) and quad (ISL28430) channel variants sharing similar electrical characteristics. The family is designed for general-purpose micropower applications requiring rail-to-rail operation. The ISL28130 specifically addresses single-channel needs in compact form factors like SC-70-5 and SOT-23-5.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include ISL28130FEZ-T7 (SC-70-5 package). Verify functional equivalence for other single-channel micropower RRIO op-amps if package changes are acceptable.
