Overview
The ISL28534FVZ-T7A is a single-channel zero-drift programmable gain instrumentation amplifier manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device features a typical gain bandwidth product of 3MHz and a maximum supply current of 3.5mA. It provides rail-to-rail input and output capabilities with a maximum input offset voltage of 10µV. The unit is housed in a 14-pin TSSOP package measuring 5mm x 4.4mm x 0.9mm, suitable for surface mount installation.
Feature Summary
- Zero-drift architecture ensures high precision with minimal offset voltage drift over temperature.
- Rail-to-rail input and output capability maximizes dynamic range within the supply voltage limits.
- Programmable gain functionality allows flexible signal conditioning for various sensor interfaces.
Applications
- Precision industrial sensor signal conditioning
- Medical instrumentation front-ends
- Strain gauge and load cell measurements
Procurement Notes
Verify component authenticity through authorized distributors due to potential availability constraints. Confirm package integrity upon receipt as the TSSOP form factor requires careful handling. Check manufacturing date codes against project timelines since this specific part number may have limited stock or end-of-life status implications. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.
Selection Notes
Select this component when ultra-low offset voltage and drift are critical for measurement accuracy. The single-channel configuration suits applications requiring one isolated high-precision amplification stage. Consider the 14-pin TSSOP footprint for PCB layout compatibility. Evaluate the 3.5mA supply current against power budget constraints compared to standard op-amp alternatives.
Part Context
This part belongs to the ISL2853x series of programmable gain instrumentation amplifiers from Renesas. It complements other variants like the ISL28533 and ISL28535 which offer different channel counts or gain configurations. The series targets high-accuracy analog signal processing needs in industrial and medical sectors where stability and low noise are paramount.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if the ISL28534EV2Z evaluation board can assist in validating alternative components during design transitions.
