ADA4528-2TCPZ-EP

Overview

The ADA4528-2TCPZ-EP is a dual-channel, zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of 2.2 V to 5.5 V (single) or ±1.1 V to ±2.75 V (dual). Key electrical specifications include a maximum offset voltage of 2.5 µV, an offset drift of 0.015 µV/°C, and a typical noise density of 5.9 nV/√Hz at 1 kHz. The device provides a gain bandwidth product of 3.4 MHz, a slew rate of 0.5 V/µs, and supports up to 40 mA output current per channel.

Feature Summary

• Zero-drift architecture ensures ultralow offset voltage and minimal temperature drift for high precision.
• Rail-to-rail input and output swing maximizes dynamic range across the full supply voltage.
• Ultralow noise performance with low flicker noise suitable for sensitive signal conditioning.

Applications

• Thermocouples and thermopiles
• Load cell and bridge transducers
• Precision instrumentation
• Electronic scales
• Medical instrumentation

Procurement Notes

Verify that the specific part number includes the EP suffix to confirm it meets Enhanced Product standards. Ensure the ordering suffix matches the required packaging format, such as tube or reel. Confirm RoHS compliance status and check for any restricted substance declarations relevant to your manufacturing process before finalizing procurement.

Selection Notes

Select this component when applications require both high precision and low noise in a compact package. The extended industrial temperature range makes it suitable for harsh environments. Verify that the supply voltage requirements align with the 2.2 V to 5.5 V operating range and that the load capacitance does not exceed stability limits for unity-gain configurations.
