14285R-100

Overview

The ISL28114 is a single-channel, low-power, rail-to-rail output operational amplifier manufactured by Renesas Electronics Corporation. It features a supply voltage range of 1.8 V to 5.5 V and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a gain bandwidth product of 5 MHz, a slew rate of 2.5 V/µs, an input bias current of 3 pA, and an input offset voltage of 500 µV. The device draws a typical supply current of 300 µA per channel and provides an output current capability of 31 mA. It is available in SOT-23-5 and SC-70-5 packages.

Feature Summary

• Rail-to-rail output capability for maximum dynamic range
• Low power consumption suitable for battery-operated applications
• High input impedance with ultra-low input bias current

Applications

• Portable instrumentation
• Battery-powered sensors
• Data acquisition systems

Procurement Notes

Verify the specific package suffix (FHZ for SOT-23-5 or FEZ for SC-70-5) and tape/reel quantity designation (T7A vs T7) against the manufacturer's official datasheet. Confirm RoHS compliance status and ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a single op-amp with rail-to-rail output and low quiescent current is required. Ensure the design accommodates the 500 µV input offset voltage and 3 pA bias current limits. Verify that the load requirements do not exceed the 31 mA output current specification while maintaining performance within the specified supply voltage range.

Part Context

The ISL28114 belongs to the ISL281xx series of precision operational amplifiers from Renesas. This series is designed for general-purpose analog signal processing tasks requiring low power and high accuracy. It complements other devices in the family such as the ISL28112 and ISL28113, which offer similar characteristics but may differ in channel count or specific performance metrics.

Replacement Considerations

Check for direct pin-compatible alternatives within the ISL281xx series or comparable parts from other manufacturers offering similar GBW, slew rate, and supply voltage ranges. Ensure any substitute maintains the same package type and thermal characteristics.
