ISL28134IBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28134IBZ-T7A is a single-channel, zero-drift, rail-to-rail precision operational amplifier manufactured by Renesas. Designed for 5V systems, it features an ultra-low input offset voltage of 2.5μV maximum and a drift of 15nV/℃ maximum. The device delivers exceptional low-frequency noise performance with only 0.25μVp-p in the 0.1Hz to 10Hz range. It operates on a single supply from 2.7V to 5.5V or dual supplies, consuming just 675μA per channel while providing a common-mode rejection ratio of 135dB.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T7A' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 'IBZ' designation aligns with the SOIC-8 package type and commercial temperature specifications. Ensure compatibility with the target system's power supply rails and signal requirements before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing precision analog front-ends requiring minimal calibration due to low offset voltage and drift. It is suitable for battery-powered devices where low quiescent current is critical. Choose this part over standard amplifiers when high common-mode rejection and low 1/f noise are necessary for accurate measurement of small differential signals from transducers.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the ISL2813x family of micro-power, zero-drift operational amplifiers. The ISL28134 variant specifically provides a single amplifier configuration, distinguishing it from dual (ISL28133) or quad (ISL28132) channel counterparts. The family is engineered for high-accuracy applications requiring stability across wide temperature ranges without external trimming.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official Renesas documentation for qualified pin-compatible alternatives within the ISL2813x series. Verify electrical parameter equivalence for any cross-reference to ensure maintained precision and low-noise performance characteristics.
