ISL28430FVZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28430FVZ-T7A is a quad-channel, micropower operational amplifier manufactured by Renesas Electronics. It features rail-to-rail input and output capabilities, optimized for single-supply (1.8V to 5.5V) and dual-supply operation. The device offers low quiescent current of 20µA per amplifier, ensuring extended battery life in portable applications. Key electrical characteristics include a gain-bandwidth product of 0.4 MHz, a slew rate of 0.2 V/µs, and an input offset voltage maximum of 40 µV. It operates within temperature ranges of -40°C to +125°C or 0°C to +70°C depending on the grade.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the order includes the correct temperature grade (commercial or industrial) as performance parameters vary between grades. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple channels are needed in a compact footprint without sacrificing precision. It is ideal for designs transitioning from older op-amps due to its standard pinout compatibility. Consider the 0.4 MHz bandwidth limit; it is not suitable for high-speed signal processing but excels in low-frequency, high-accuracy applications. Evaluate the 20µA supply current against system power budgets to ensure optimal efficiency.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28430 belongs to the ISL28x30 family of micropower, low-offset amplifiers, which also includes single-channel (ISL28130) and dual-channel (ISL28230) variants. This family is designed to replace higher-power general-purpose op-amps in portable applications. The T7A suffix typically denotes a specific reel quantity and packaging format for automated assembly.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements include ISL28230 for dual-channel needs or ISL28130 for single-channel requirements within the same package families. Verify pinout compatibility before substituting. Other micropower RRIO op-amps may require schematic adjustments due to differing pin configurations or electrical characteristics.
