EL8173FSZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL8173FSZ-T7 is a single-channel instrumentation amplifier from the Renesas EL8171 series, housed in an SOIC-8 surface-mount package. It operates on a single supply voltage ranging from 2.4 V to 5.5 V with a typical quiescent current of 95 µA. Key electrical specifications include a 3 dB bandwidth of 450 kHz, a common-mode rejection ratio (CMRR) of 75 dB, and a power supply rejection ratio (PSRR) of 75 dB. The device features low input bias current of 50 pA and an input offset voltage of 1.5 mV. It supports rail-to-rail output and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer part number against official Renesas documentation to ensure authenticity. Confirm that the SOIC-8 package and tape-and-reel packaging match project requirements. Check for RoHS compliance status as indicated in the specific datasheet revision. Ensure availability aligns with production schedules due to potential limited stock situations reported by distributors.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-power, single-supply instrumentation amplifier with rail-to-rail output is required. The 450 kHz bandwidth and 75 dB CMRR make it suitable for precision applications where power efficiency is critical. Compare input offset voltage and bias current specifications against other members of the EL817x family if higher precision or multiple channels are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL817x family of micro-power instrumentation amplifiers designed by Renesas (formerly Intersil). The EL8173 variant specifically provides a single channel configuration. It is often compared with the EL8171 (single channel) and EL8172 (dual channel) models within the same product line, sharing similar electrical characteristics but differing in channel count and package options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The EL8171FSZ-T7 is a single-channel alternative within the same family. Verify pin compatibility and electrical parameter equivalence before substitution. No direct cross-manufacturer substitutes are confirmed in the provided data.
