EL5223CRZ

Overview

The EL5223CRZ is an octal buffer operational amplifier manufactured by Intersil. It features a bandwidth of 12 MHz and supports rail-to-rail input and output operation. The device operates within a supply voltage range of 4.5 V to 16.5 V, with a maximum dual supply of +/- 8.25 V. It draws a typical operating current of 1.35 mA per channel. The unit is housed in a TSSOP-20 surface-mount package and functions as a low-power voltage feedback amplifier.

Feature Summary

• Octal configuration providing eight independent buffer channels in a single package
• Rail-to-rail input and output capability for extended dynamic range
• Low power consumption design suitable for battery-operated applications

Applications

• Multi-channel signal buffering in data acquisition systems
• Isolation between high-impedance sources and low-impedance loads
• Driving multiple ADC inputs from a single source

Procurement Notes

Verify the specific suffix (CRZ) against the manufacturer's datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status and moisture sensitivity level before procurement. Check for end-of-life notifications or obsolescence warnings from Renesas/Intersil, as availability may be restricted.

Selection Notes

Select this component when multiple buffered outputs are required without increasing board space significantly. Ensure the 12 MHz bandwidth meets the signal frequency requirements. Verify that the rail-to-rail performance aligns with the system's voltage swing needs. Consider the TSSOP-20 package constraints during PCB layout planning.
